Design analysis of PCB power supply system

10/09/2023 в /от

Сегодня, 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. Фактически, 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, полупроводник, коммуникации, 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, efficiency, safety and cost.

➤ Component selection: According to the circuit design, select appropriate components such as resistors, конденсаторы, индукторы, и т. д.. 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.

Solutions

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. Например, 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. Например, 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. Например, the main power line and ground line should be thickened to reduce internal resistance; в то же время, 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. Например, 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.

Заключение

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. Поэтому, we need to constantly update our design concepts and methods to adapt to changing market demand and technology trends.

Это основная причина, почему важно обращать внимание на толщину платы после завершения проектирования схемы и перед заказом на производство..

4. Согласование воздействия должно быть хорошим

Каждая многослойная плата действует как конденсатор на соседнем слое.. Вот почему толщина печатной платы так важна.. Толщина материала печатной платы FR4 определяет толщину диэлектрика., что в свою очередь влияет на значение емкости.

Это особенно критический фактор для некоторых высокочастотных печатных плат., такие как радиочастотные и микроволновые конструкции. В высокочастотных конструкциях основное внимание уделяется индуктивному гашению как важному компоненту для поддержания оптимальной функциональности платы., и получение правильной емкости для каждого слоя имеет решающее значение.

5. Гибкие возможности

Гибкость — еще один важный фактор, который следует учитывать при выборе толщины материала печатной платы FR-4.. Чем тоньше доска, тем он более гибкий. Из-за жары, очень гибкие и тонкие печатные платы часто подвергаются высокому риску пайки из-за изгиба и изменения угла во время использования.. Управление теплом должно быть приоритетом в этих проектах..

Потому что более тонкие печатные платы демонстрируют эффективную работу при обычных нагрузках на гибкие продукты.. Они имеют широкий спектр применения в медицинском и автомобильном оборудовании..

6. Требования к конструкции и весу

Тонкие печатные платы легкие и небольшие по размеру., тем самым облегчая бытовую электронику. Это легко осуществить, а также снижает затраты на транспортировку материала.. Но тонкие доски не являются ответом на большие доски.. Увеличение размера тонких плат может привести к поломке и изгибу печатной платы.. Однако, слишком толстые платы занимают большую площадь поверхности и увеличивают общий вес модуля/устройства., что имеет свои последствия.

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. Поэтому, protecting the PCB well has become an important item. Здесь, 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, и химикаты. 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, влага, and voltage leaks. Potting also shields electronics from the effects of vibration and stress, preventing wiring disconnections and early system failure.

2.Кроме того, 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.Также, Encapsulation protects PCBs from dirt and dust, which can cause overheating, signal interference, and decreased speed or performance.

4.Наконец, 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. Однако, 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. Однако, 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, однако, 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. Например, silicone and epoxy are perfect for the circumstances under high temperatures; однако, 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. Insulation: 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. Припаяность: 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. Расходы: The cost of the coating material is also one of the factors to be considered when selecting the material.

Process flow of PCB potting board

PCBA function test guide

09/11/2023 в /от

печатная плата Functional testing, which is performed to ensure that the product meets the design requirements both in terms of product description, user plans and operating programs, is performed according to the characteristics of the product description, user plans and operating programs. Functional testing ensures that the program works properly, tests the software against functional requirements, and tests all features and functions of the system to ensure that it meets the requirements and specifications.

Functional testing is also known as black box testing or data driven testing because only the various functions need to be tested one by one from the software product interface, the test case architecture based on written requirements, and the evaluation of the input data between the expected results and the actual results one by one, not the internal structure and code of the software.

PCBA functional testing will cover both hardware and software. The customer must send the test plan to the manufacturer to guide the test engineers. You need to list the behaviors and results (НАПРИМЕР., if you press, например, button one, the green light comes on).

Why need Functional Testing

The purpose of PCBA functional testing is to ensure the quality of the product, improve the product qualification rate, improve the production process and get a better user experience. Functional testing can gain these following benefits:

·By simulating the operating environment for the Сборка печатной платы under test, functional testing minimizes the cost for the customer. It is not necessary to provide the real and expensive testing equipment.

·It helps to avoid expensive system tests that often save the customer time and financial resources.

·It is possible to test 50-100% of the product before shipping, thereby minimizing the customer’s time and effort to test and debug the PCB assembly.

·It is possible for skilled professionals to extract the maximum productivity with a functional test, making this the most effective testing apart from a full system test.

·Along with ICT and flying probe tests, functional testing can make the PCB assembly error free and more robust.

PCBA function test method

1. Manual Test Fixture

Manual test fixtures use baking paint and acrylic pinboard output PCB input/output and power supply, and manually simulate input/output. The results are confirmed by the tester.

Due to high labor costs and low efficiency, manual testing is gradually replaced by manual test fixtures, which are only part of the test, but less demanding and less costly for manual participation.

2.MCU control function test

Make the fixture lock or pneumatic fixture and pull out the probe. Then connect the input/output power supply to the microcontroller circuit so that the microcontroller can run the test program and automatically measure the analog input/output.

This method is characterized by moderate price, high test efficiency, guaranteed test quality and less human intervention. Однако, this method lacks versatility is generally only applicable to machines equipped with fixtures.

3.PCBA Universal Automated Test System

PCBA universal automated test system designed for most manual testing and design. Because the test system is powerful, you can test a variety of PCBA and become a universal test system.

Humanized test principle: By sampling the model parameters, setting the error range, and comparing with the test board to determine whether it is qualified or not.

Simplicity test: Press the needle bar manually and the system automatically handles it. Product quality can be judged by the system, excluding the influence of human judgment factors. Более того, its speed is incomparable to manual testing.

The system consists of acquisition, control board and test software. It is connected to a programmable AC/DC power supply and DC load. High sample rate products can be equipped with an external oscilloscope.

The system can test PCBA synchronization signals, user interfaces, modular programming environment models and conversions.

This method is costly, but testing is fast and requires no human intervention. It is versatile in its application and provides more comprehensive testing.

PCBA function test content
