The characteristics and application introduction of purple PCB

/在： /通过：

The color of the printing circuit board is determined by the color of the group welding layer. Our common PCB boards are black, blue, green, and purple. What we want to discuss today is the detailed information about the purple circuit board. The specific content is as follows:

What is purple PCB?

Purple PCB, a circuit board with a purple welded layer, is determined by the welding layer of the circuit. Purple welded layer not only provides the color of the circuit board, but also may improve the performance of the circuit board. However, because purple is not a standard color, it may need to place orders to the circuit board manufacturer alone to provide, which may increase the manufacturing cost.

Purple PCB material

The materials of the purple circuit board mainly include the following:

1.FR4 board: This is a commonly used material that makes the circuit board strong and waterproof, and provides good insulation, thereby improving signal integrity. FR4 plate is a material made of epoxy resin and glass fiber cloth. It has the characteristics of medium mechanical strength, good dielectric performance, heat resistance, moisture, and chemical corrosion.

2.CEM-1 and CEM-2: These composite boards are also commonly used circuit board materials, which have good electrical and processing performance.

3. Special boards: such as ceramic boards and metal plates, these materials have special performance and use, which can meet certain special application needs.

In addition, according to the manufacturing process and use of the circuit board, other types of materials may be used, such as cardboard (such as FR-1, FR-2, FR-3), HDI boards, etc.

It should be noted that the color of the purple circuit board is determined by the welding layer of the circuit, not determined by the material itself. Therefore, no matter which material is used, as long as the welding layer is used to use purple ink, a purple circuit board can be made.

Benefits and Limitations of Purple PCB

 

The Benefits of Purple PCBs

Visual Appeal and Branding
In a market where differentiation can be a key factor in success, the unique color of a purple circuit board can make a significant impact. This is particularly true for consumer electronics, where the internal design of a device, including its circuit board, can be a point of aesthetic distinction.

Enhanced Inspectability
The contrast between the vibrant purple solder mask and the metallic sheen of the silver traces can make it easier for engineers and technicians to spot issues or defects during the manufacturing process or in quality control checks.

Material Advantages
The use of polyimide or other specialized materials for achieving the purple color can also offer functional benefits. These materials often exhibit superior heat resistance and flexibility compared to the standard materials used in green PCBs.

The Limitations of Purple PCBs

Availability and Lead Times
The specialized materials and dyes required for purple solder masks are not as commonly used as those for green PCBs, leading to potential issues with sourcing and longer lead times. For projects on a tight schedule or for manufacturers accustomed to rapid production cycles, this can pose a logistical challenge.

Higher Costs
The lower demand for purple solder masks, combined with the specialized processes required to produce them, often results in higher prices compared to standard green PCBs. For large-scale projects or for companies with strict budget constraints, the additional cost of purple circuit boards might be a prohibitive factor.

Purple PCB Applications

Purple PCBs have found a place in a wide range of applications, including:

Electronics and Gadgets
Many innovative companies and startups are choosing purple PCBs to give their products a unique and captivating appearance. The vibrant color helps create an emotional connection with customers, making their devices more memorable and enticing.

DIY Projects and Makerspaces
In the realm of DIY enthusiasts and makerspaces, purple PCBs have become a symbol of creativity and self-expression. The color’s emotional allure inspires hobbyists to push the boundaries of their projects, fueling their passion for electronics.

Wearable Technology
With the rise of wearable technology, purple PCBs are increasingly being used in devices like smartwatches, fitness trackers, and VR headsets. The distinctive color adds a touch of flair and personal style, making the technology feel like an extension of the wearer’s personality.

The characteristics of purple PCB

The characteristics of purple PCB mainly include the following aspects:

1. Recognition: The appearance of purple makes the circuit board more conspicuous among many electronic devices, which helps improve the recognition and brand image of the product.

2. Thin -type: The amount of copper used in conventional purple PCB circuit boards is small, which makes the size of the circuit board very thin and helps to achieve lightweight and portability of the equipment.

3. Circuit isolation: By adding the purple box, different functional modules of the circuit board can be separated to reduce signal interference and improve the reliability and stability of the circuit board.

4. Signal processing: The purple box can also be used to define the boundary of the signal processing circuit to ensure the accuracy and accuracy of the signal transmission. At the same time, it also helps the guidance and transmission of managing signals on multi -layer circuit boards.

5. Power distribution: By adding purple boxes to the PCB layout, the area of the power distribution network can be determined to improve the traceability of the power cord and help solve the problem of power jump lines.

FAQs About Purple PCBs:

Why are green PCBs more common than purple PCBs?
Green PCBs have been the industry standard for decades due to their lower production costs and ease of sourcing materials. However, as technology has advanced, colored PCBs like purple have become more accessible and affordable.

Can purple PCBs be used in high-frequency applications?
Yes, purple PCBs can be used in high-frequency applications, just like any other PCB. The color of the solder mask does not impact the PCB’s performance or functionality.

Are purple PCBs suitable for all types of electronic projects?

Absolutely! Purple PCBs can be used in a wide range of applications, from consumer electronics to DIY projects and wearable technology.

Do purple PCBs have any disadvantages compared to other colors?
The primary disadvantage of purple PCBs is their relative rarity compared to more common colors like green. This may make sourcing purple PCBs slightly more challenging. However, their unique appearance and the emotional impact they create can outweigh this minor inconvenience for many electronics enthusiasts.

How can I ensure the quality of my purple PCB?
To ensure the quality of your purple PCB, work with a reputable manufacturer like MorePCB that has a proven track record of producing high-quality PCBs. Make sure to follow their design guidelines and properly care for your PCB to maintain its performance and appearance.
