2-layer PCB VS 4-layer PCB: Advantages and Disadvantages Introduction

/em /por

When manufacturing electronic products, the selection of the type of circuit board is a relatively important step. Por exemplo, whether to use single-layer PCB, 2-layer PCB, ou PCB multicamadas. Claro, these issues are in the product design stage . Each type of PCB has unique advantages. We must choose according to the performance of the product.

Now we will discuss the advantages and disadvantages of 2-layer PCBs and 4-layer PCBs. O conteúdo específico é o seguinte:

Introduction to the concept

What is a 2-layer PCB?

A 2-layer circuit board is a circuit board with only two conductive layers and no gaps between the layers. Each layer can be wired for circuits, and the two layers do not lead to each other. This type of circuit board is generally used for simpler circuit designs, such as some small electronic devices, brinquedos, etc.. Its advantages are easy to manufacture, baixo custo, suitable for small-scale production, etc..

What is a 4-layer circuit board?

A 4-layer circuit board is a circuit board that has four conductive layers with vias connecting the layers. This type of board is often used for more complex circuit designs, como equipamento de comunicação, computer networks, etc.. It has the advantage of providing more circuitry. Its advantages include more wiring space, higher signal quality and more stable performance.

4-layer circuit boards are more difficult to design and fabricate, and require a higher level of technology and equipment, so their cost is also relatively high. No entanto, it can provide better signal quality and more stable performance, and is suitable for application scenarios that require higher circuit performance.

2-Layer PCB Advantages and Disadvantages

Vantagens

▶ Lower Cost – double sided PCBs are less expensive than 4-layer designs. This difference can be considerable depending on the number of units you intend to order.

▶ Simpler Design and Production – simpler design and production not only means you get your printed circuit boards faster. The simpler your design is, the less vulnerable it is to costly errors during the design or manufacturing process. In certain applications, the ability to repair your PCB at a later date is also important; when compared to more complex 4-layer PCBs, it is inherently easier to repair double sided printed circuit boards.

▶ High Volume – Whenever projects require mass production, eliminating unnecessary layers is vital. If your project is going to be a high-volume order, 2-layer boards are typically preferred to optimize manufacturing speed, custo, and efficiency.

▶ Short Lead Time – For large and small projects, a shorter lead time is often required to quickly make a prototype. 2-layer PCBs have an advantage over other multilayer printed circuit boards, because they are extremely fast to produce.

Desvantagens

▶ Simplistic Design – Oftentimes opting for a double sided circuit board means sacrificing some bells and whistles. A 4-layer PCB has more room for more components and routing options, while a 2-layer PCB typically has a simple design.

▶ Slower Speed and Lower Operating Capacity – If speed is an issue, the more layers, Quanto melhor. Depending on the application, you may find that 2 layers isn’t enough to give you the necessary speed and capacity for your project. The jump from 2 layers to 4 layers includes considerably more speed and operating capacity.

▶ Larger Size and Higher Weight – Despite 4-layer printed circuit boards having more layers, double sided PCBs are typically quite large and bulky in comparison to make room for components and leads. If you need to fit your printed circuit board into a compact space, adding more layers is often the best design choice.

4-Layer PCB Advantages and Disadvantages

Vantagens

▶ Useful for More Complicated Projects – The more complex your project is, the more useful you will find the additional layers of a 4-layer PCB. Being able to increase your creative design choices including layouts, routing, and additional components, gives you the opportunity to make the best end product possible.

▶ High Quality – For even simple products that demand the highest quality, going from a 2-layer to a 4-layer Design de PCB is an obvious choice. If cost is not an issue, 4-layer boards offer a higher quality result.

▶ Added Power – The ability to handle more power is a considerable advantage for 4-layer PCBs. When you are deciding whether you need a double sided or 4-layer printed circuit board, keep in mind how much power your design will require.

▶ Increased Durability – The more layers your design has, the more durable your PCB will be. UM 4 layer design will be much more substantial than a 2-layer printed circuit board, despite typically being smaller in size.

▶ Smaller Size and Lighter Weight – While many people conflate a larger number layers with a larger sized board, 4-layer boards are actually often much smaller and lighter than 2-layer PCBs. This is because they require less room for components and wiring.

Desvantagens

▶ Higher Costs – Since 4-layer PCBs use more materials and are more difficult to manufacture, they can be quite a lot more than 2-layer printed circuit boards. When costs are an issue, minimizing the number of layers is usually the best option.

▶ More Complicated Design and Production – When you need to quickly design and produce printed circuit boards for a project, the more layers you have, the longer each step of the process is going to take.

▶ Less Availability – You will find that the more complex your design is, the harder it is to find a manufacturer who can accommodate your needs. That being said, 4-layer designs are very common these days, so this becomes more of an issue as your PCB designs begin to get even more complicated.

▶ Longer Lead Times – For projects that are in a time crunch, adding layers to your design isn’t ideal. The smaller your timeframe is, the more important it will be to use as few layers as possible for your project.

▶ More Complex Repairs – Double-sided printed circuit boards have an advantage over 4-layer designs when it comes to ease of repairs. While everything is essentially exposed on 2-layer designs, any necessary repairs for 4-layer PCBs are going to be more difficult. For some applications, this is extremely important and should be taken into consideration.

Análise de projeto do sistema de fonte de alimentação PCB

/em /por

Hoje, it is difficult to successfully design high-speed electronic systems without a thorough understanding of the power supply system characteristics of the chip, package structure and PCB. Na verdade, in order to meet the requirements of lower supply voltages, faster signal flip-flops, higher integration, and many more challenging requirements, many companies at the forefront of electronic design have invested a lot of money, manpower, and resources in the analysis of power supply systems to ensure the integrity of power supplies and signals during the product design process.

Power supply system (PDS) analysis and design is becoming increasingly important in the field of high-speed circuit design, especially in the computer, semicondutor, comunicações, networking and consumer electronics industries. With the inevitable further isotropic shrinkage of ultra-large-scale integrated circuit technology, the supply voltage of integrated circuits will continue to decrease. As more and more manufacturers move from 130nm technology to 90nm technology, it is expected that the supply voltage will drop to 1.2V or even lower, while at the same time the current will increase significantly. From DC IR voltage drop to AC dynamic voltage fluctuation control, this development trend poses a great challenge to the design of power supply systems as the allowable noise range becomes smaller and smaller.

The design of PCB power supply system mainly involves the following aspects:

➤ Circuit design: according to the needs of the equipment, design a reasonable power supply circuit. This requires consideration of factors such as circuit stability, eficiência, safety and cost.

➤ Component selection: According to the circuit design, select appropriate components such as resistors, capacitores, Indutores, etc.. to meet the performance and cost requirements.

➤ Wiring Arrangement: Determine the layout and alignment of components on the circuit board to reduce the internal resistance of the power supply, avoid electromagnetic interference, and improve the reliability of the system.

➤ Heat dissipation design: Considering that the power supply generates heat during operation, it is necessary to design a reasonable heat dissipation scheme to ensure the stability and reliability of the power supply system.

Technical Challenges

In the design of PCB power supply system, the following technical challenges may be encountered:

▲ Circuit stability: The stability of the power supply circuit directly affects the performance of the entire device. Unstable or fluctuating power supply circuits may cause the device to malfunction or not work properly.

▲Component durability: Components in the power supply system may wear out or fail during operation. How to improve the durability and reliability of components is an important issue to be addressed in the design of the power supply system.

▲System anti-interference ability: power supply system in the working process, may be subject to electromagnetic interference from the outside world, how to improve the anti-interference ability of the system in the power supply design, is also an important technical challenge.

Soluções

In response to the above technical challenges, the following are some possible solutions:

〓 Circuit Design Optimisation: Adopt reasonable circuit topology and component layout to improve the stability and efficiency of the power system. Por exemplo, power supply circuits that require high stability, mature and stable power supply topologies such as LDOs (Low Noise Linear Regulators) or switching power supplies can be used.

〓 Component Quality Assurance: Select components with reliable and durable quality, and consider factors such as component tolerance and thermal characteristics in the design process. Por exemplo, grade X and Y resistors and capacitors are selected to meet the needs of high temperature, high humidity and harsh environments.

〓 wiring arrangement is reasonable: in the circuit board layout and alignment design, the power supply internal resistance and electromagnetic interference should be fully considered. Por exemplo, the main power line and ground line should be thickened to reduce internal resistance; ao mesmo tempo, a reasonable signal line layout and filtering design should be adopted to reduce electromagnetic interference.

〓 heat dissipation design: according to the actual working condition, choose the appropriate heat dissipation scheme. Por exemplo, for power modules with large power, active heat dissipation methods such as heat sinks or fans can be used; for power chips with small power, natural heat dissipation can be used.

Conclusão

PCB power supply system design is an important part of electronic equipment. In the actual design, we must give full consideration to technical challenges such as circuit stability, component durability and system anti-interference ability, and improve the performance and reliability of the power supply system by optimizing circuit design, ensuring component quality, and rationally arranging wiring and heat dissipation design. In the future electronic equipment, with the continuous progress of technology and the continuous expansion of application scenarios, the design of PCB power supply systems will face more new challenges. Portanto, we need to constantly update our design concepts and methods to adapt to changing market demand and technology trends.

Custo e preço de PCBs flexíveis

2. Número de camadas: O número de camadas de um PCB flexível também é um dos fatores que afeta o preço. Menos camadas são geralmente mais baratas do que mais camadas.

3. Largura e espaçamento da linha: A largura e o espaçamento flexíveis da linha PCB também afetarão o preço. Linhas e espaçamentos mais estreitos exigem maior precisão e tecnologia de fabricação, então o preço é mais alto.

4. Quantidades de produção: O preço dos PCBs flexíveis geralmente aumenta à medida que o número de PCBs flexíveis diminui, e PCBs flexíveis produzidos em massa são geralmente mais baratos do que pequenas quantidades de PCBs flexíveis.

5. Prazo de entrega: O prazo de entrega do PCB flexível também é um fator no preço. Se um PCB flexível precisar ser entregue rapidamente, o fabricante pode precisar trabalhar horas extras ou usar métodos de fabricação mais caros, então o custo será maior.

6. Complexidade do projeto: A complexidade do design do PCB flexível também é um dos fatores que afetam o preço. Projetos complexos exigem tecnologia mais avançada e mais etapas de fabricação, e portanto custa mais.

7. Largura e tamanho do traço de cobre

A largura do traço de cobre é outro fator chave no custo de PCBs flexíveis. Como os traços de cobre desempenham um papel vital na transmissão de sinais e na condução de corrente, é necessário espaço adequado para melhorar o design flexível e reduzir os custos de PCB flexível. Se o alinhamento estiver muito apertado, o custo do PCB flexível será alto e difícil de projetar; portanto, o alinhamento do cobre deve ser mantido a uma distância adequada um do outro para melhorar o custo e a confiabilidade do PCB flexível.

8. Espessura do traço de cobre

Quanto mais espessos os traços de cobre, quanto maior o custo dos PCBs flexíveis. Como a camada interna do PCB flexível requer uma camada de cobre mais espessa, mais pré-impregnado é necessário para completar a laminação, o que aumenta o custo do PCB flexível. Para controlar o custo de PCBs flexíveis, use alinhamento de cobre fino. É melhor você usar meia onça. Traço de cobre na camada interna e 1 Oz. no traço externo.

How to build a prototype PCB？

/em /por

Before a circuit board is mass produced, it is important to ensure that the entire product functions properly. This requires a complete product test before mass production. If you want to achieve this function, then you need to make a prototype PCB. Próximo, we introduce the Protótipo de PCB information in detail.

What is a prototype PCB

PCB prototypes are models or samples of the appearance and function of the final PCB, and are mainly used in the experimental stage to prove the feasibility of the design and detect any potential problems. With Montagem de protótipo de PCB, manufacturers can get a snapshot of the entire process and eliminate errors before a full production run to ensure everything works as expected when it comes to mass production.

Why do I need to build a PCB prototype?

The main purpose of PCB prototyping is to verify the design idea and test the product function, mainly in the following aspects:

1. Design and functional testing: The prototype PCB board can help engineers in the development process identify defects as early as possible. The more accurate the design, the more ready the defect identification is to minimize the design cost, but also shorten the project time. Through the prototype, engineers can perform functional testing to assess whether the product’s function meets expectations.

2. Conditional testing: Many products need to be applied to special environments, so PCB products must be properly tested to ensure proper operation in the environment. Por exemplo, prototypes are usually subjected to temperature change tests, power change tests, impact resistance tests, etc.. to ensure the reliability and stability of the product.

3. Accelerate overall production: Highly accurate PCB prototypes help minimize iterations and rework that can occur during the production phase.

What is FR4 PCB board ?

/em /por

There are many types of PCB substrate, such as fiberglass board, paper substrate, substrato de metal, PCB de cerâmica, etc., different environments use different materials of the basic. Próximo, I will share with you the details of FR4 PCB board.

What is FR4 PCB board?

FR4 is a PCB substrate that is a glass fiber reinforced epoxy laminate in the form of raw material and substrate for circuit boards. Due to its robust nature and flame retardant properties, FR4 is a common laminate substrate used on printed circuit boards and it is vital to provide the required insulation to circuit boards.

FR4 boards have largely replaced G-10 boards.FR4 materials use bromine, a halogen chemical element that is fire-resistant and therefore valuable in providing flame-retardant properties.It is also unable to absorb water and maintains a high level of mechanical strength in addition to incredible insulation capabilities, especially in wet or dry environments.FR4 materials also have high glass transition temperatures ranging from 115 para 200 degrees Celsius, and its FR-4 flame-resistant material class code, which meets UL94V-0, ensures that it will not spread and extinguish the material as soon as it begins to burn.

Typical single, dupla face, e PCB multicamadas circuit boards are made of FR-4, which is so strong and flame-resistant that most circuit boards choose FR-4 as a substrate. FR in FR-4 stands for flame retardant, and the number 4 distinguishes the material from others in this category.FR-4 is a fiberglass reinforced epoxy laminate, which looks like a thin, woven-cloth sheet. The term FR-4 also stands for the grade used to make these laminates. Fiberglass construction provides structural stability to the material. The fiberglass layer is covered with flame retardant epoxy resin. This brings durability and strong mechanical properties to the material.

What are the advantages of FR4 PCB boards?

1. High insulation: FR-4 material has high insulation performance, which can effectively prevent current leakage, thus ensuring the safety and stability of electronic products.

2. High heat resistance: FR-4 material has high heat resistance and can maintain good performance at high temperatures, thus showing good stability in some high temperature environments.

3. High moisture resistance: FR-4 material has good moisture resistance, can maintain good performance in humid environments, so it has a wide range of applications in some humid environments.

4. Good machinability: FR-4 material has good machinability and can be drilled, cut, ground and other machining operations, thus facilitating the production and processing of PCBs.

5. Low-cost materials

FR-4 printed circuit board materials are widely available and inexpensive. Nevertheless, they provide excellent functionality. No entanto, high glass transition temperatures and high relative leakage trace index materials are somewhat expensive.

Applications of FR4 PCB boards

FR4 PCB boards are used in many electronic products, such as cell phones, TVs, and stereos. Due to its high strength, high rigidity and flame retardancy, FR4 PCB board can be adapted to a variety of circuit board design shapes and sizes, and has excellent dielectric constant and dielectric loss performance, so it is also widely used in the field of radio frequency circuits and high-speed signal transmission.

Além disso, FR4 PCB boards are also used in the field of industrial control systems. Due to their excellent high frequency characteristics in electrical performance, they can be used for high frequency circuit design such as production line control and robot control.

In some specific areas, such as the military field, FR4 material flame retardant performance has also reached strict standards. Both high performance and safety can be used for surveillance systems, missile systems and other military equipment, high frequency routing and control circuit design.

How to choose FR4 thickness

The thickness of the circuit board is easily overlooked when designing, but it has important properties. The thickness of a circuit board affects the proper use of the entire circuit.

When ordering laminates for a PCB project, the designer or electrical engineer must specify the FR4 thickness. This is measured in inches, such as thousandths of an inch, thousandths of an inch, or millimeters, depending on which unit is most suitable for the setup. Depending on the needs of the project, the thickness of FR4 sheet varies widely, but is usually between 10,000 e 3 polegadas.

1. Espaço: The thinner the better

Some electronic devices have less space available, such as Bluetooth accessories, use linkers, etc.. For these products, smaller FR4 PCBs are often preferred to save space inside the device.

2. Impedância Controlada

Some high-frequency/high-speed boards require controlled impedance. We know that a stable dielectric constant (Dk) and a low dielectric constant thermal coefficient help achieve controlled impedance. Maintaining the thickness balance of FR-4 material is critical. Thin PCBs face high heat and an increased thermal coefficient of dielectric constant (TCDK), which leads to fluctuations in dielectric constant (DK). Portanto, manutenção Espessura da PCB is critical to achieving a low dielectric constant (Dk).

3. Connections

Two PCBs need to be connected to each other by an edge connector or another matched socket. Connectors are only available in a limited number of sizes. Therefore they are only suitable for a specific PCB thickness. This can be a limiting factor for PCB thickness. If an existing PCB is being redesigned and is part of an older system, the PCB thickness must be checked twice. This is the fundamental reason why it is important to pay attention to the thickness of the board after the circuit design is completed and before ordering for manufacturing.

4. Impact matching should be good

Each multilayer board acts as a capacitor on an adjacent layer. This is why the thickness of the circuit board is so important. PCB FR4 material thickness determines the thickness of the dielectric, which in turn affects the capacitance value.

This is a particularly critical factor for some high-frequency PCBs, such as RF and microwave designs. High frequency designs focus on inductive quenching as an important component to maintain optimal board functionality, and getting the right capacitance for each layer is critical.

5. Flexibility Options

Flexibility is another important factor to consider when choosing the thickness of FR-4 PCB material. The thinner the board, the more flexible it is. Due to heat, highly flexible and thinner PCBs are often at high risk of soldering due to bending and angle changes during use. Heat management should be a priority in these designs.

Because thinner PCBs show effective performance against conventional stresses on flexible products. They have a wide range of applications in medical and automotive equipment.

6. Design and weight requirements

Thin PCBs are lightweight and small in size, thus facilitating consumer electronics. It is easy to carry out and also reduces the transportation cost of the material. But thin boards are not the answer to large boards. Increasing the size of thin boards can lead to PCB breakage and bending. No entanto, extra thick boards take up a larger surface area and increase the total weight of the module/device, which has its own consequences.

Materials and processes for PCB potting

/em /por

There is a PCB board in all electronic devices, and the service life of these products basically depends on the service life of the PCB. Portanto, protecting the PCB well has become an important item. Aqui, LST introduces a technology that can protect PCB well, it is PCB potting.

What is potting PCB?

Potting is a way of protecting PCBs from heat, environmental hazards, e produtos químicos. This is mainly due to the fact that the outer shell of the PCB is filled with a substance that is used to protect the entire PCB and components.

1.Potting enhances electronic performance and circuit dependability by protecting PCBs from tampering, umidade, and voltage leaks. Potting also shields electronics from the effects of vibration and stress, preventing wiring disconnections and early system failure.

2.Adicionalmente, the PCB and PCB case’s vibration waves may pair, intensifying stress on the PCB and causing early failure. PCBs become stress and vibration resistant through potting.

3.Também, Encapsulation protects PCBs from dirt and dust, which can cause overheating, signal interference, and decreased speed or performance.

4.Lastly, PCB board potting improves the security and privacy of the electronic device. The nature of potting makes accessing your PCB and reverse engineering your device incredibly challenging, thereby enhancing the privacy and security of your PCB board.

5 types Potting Compounds

One option is epoxy, which is a durable material with great chemical resistance and high adhesion strength. No entanto, epoxies require a long time to fully cure and set.

Polyurethane is another choice – it is softer and more pliable than epoxy. This makes polyurethane useful for protecting fragile electronic components that may not work well with rigid potting compounds. No entanto, polyurethane tends to have lower heat and moisture resistance compared to some alternatives.

Silicone can also be used for potting PCBs. It is extremely flexible and can withstand extreme temperatures. The downside is that silicone tends to be more expensive than other potting materials, so it may not be practical depending on the application.

Acrylic adhesives are readily soluble in many organic solvents, making it easy to complete repairs to panels and often providing only selective chemical resistance. Acrylic adhesives offer the advantages of quick drying, good mold and mildew resistance, no shrinkage during curing and good moisture resistance. The disadvantages, no entanto, are low abrasion resistance and susceptibility to scratching, chipping and peeling.

The last species is urethane, which is very protective, hard and highly resistant to solvents, providing excellent abrasion resistance and low moisture permeability. It also has good low-temperature adaptability, but does not work well in high-temperature environments and most cannot be repaired or reworked.

Various materials have different pros and cons that should be considered, choosing the right material is determined by applications. Por exemplo, silicone and epoxy are perfect for the circumstances under high temperatures; no entanto, urethane would have the better protection performance to chemicals. So the key point that we should notice when selecting the material is that we need to have a clear thought about what kind of protection we want to achieve.

How to choose PCB potting materials

The following factors need to be considered when choosing a coating material for circuit boards:

1. Heat resistance: circuit boards usually operate at high temperatures, so the coating material must be able to withstand high-temperature environments.

2. Isolamento: The coating material should have good insulation to prevent the circuit board from short-circuiting or other electrical failures.

3. Chemical resistance: Since the circuit board may come into contact with various chemicals during use, the coating material needs to be chemically resistant.

4. Soldabilidade: The coating material should be solderable to facilitate the soldering and repair of the circuit board.

5. Wear resistance: the circuit board may be subject to wear and tear during use, so the coating material needs to have a certain degree of wear resistance.

6. Custo: The cost of the coating material is also one of the factors to be considered when selecting the material.
