1. PCB patch processing has become increasingly popular and prevalent in the electronics industry.
2. PCB boards come in various colors, which are primarily attributed to the solder mask.
3. The solder mask plays a crucial role in PCB patch processing by preventing component damage.
4. Incorrect soldering can shorten the device’s lifespan and increase susceptibility to oxidation or corrosion.
5. Generally, the predominant color of PCB boards is green.
6. Why is green the most common choice, and what benefits does it offer?
7. This is mainly due to the fact that the green solder mask process is the most developed and straightforward.
8. Additionally, green boards are more environmentally friendly.
9. Beyond green, PCB boards are also available in white, yellow, red, blue, matte finishes, and even shades like chrysanthemum, purple, black, and bright green.
1. White exists as a color primarily used for lamps and lanterns, while other colors are mostly utilized to differentiate product samples.
2. Throughout the company’s journey from R&D to product implementation, the PCB’s color varies based on its application; for instance, experiment boards might be purple, key boards red, and internal computer boards black, all distinguished by their color coding.
3. The green solder mask ink has a long-standing history, being inexpensive and widely used due to several advantages:
4. In PCB processing, electronic product production includes board fabrication and subsequent filming. During this process, there are multiple stages that require a yellow light room, where the visual appeal of green PCBs is enhanced.
5. Moreover, during SMT assembly, the tinning, placement, and AOI verification steps necessitate optical positioning calibration, and the green substrate is more instrument-friendly for recognition.
6. A portion of the inspection relies on human observation (though most now use flying probe testing instead), and when viewed under bright light, green is easier on the eyes.
7. Additionally, green PCBs are relatively eco-friendly; when waste boards undergo high-temperature recycling, they emit no toxic gases.
8. In contrast, other colors, like blue and black, contain cobalt and carbon, respectively, which may have low electrical conductivity and pose short circuit risks.
9. Furthermore, darker colors like black, purple, and blue complicate the inspection and maintenance of motherboards, making process control more challenging.
10. Taking black boards as an example, their production is often hindered by raw material ratios; a small error can lead to significant color discrepancies, increasing the PCB defect rate.
11. The traces on black circuit boards are harder to distinguish, complicating post-maintenance and debugging efforts. Many PCB manufacturers tend to avoid using black PCBs.
12. Even in military and industrial control sectors, where quality is paramount, green PCB substrates remain the preferred choice.
13. The PCB board’s color does not influence its performance in any way.
14. While the green color of PCBs does offer numerous benefits, it has no direct impact on performance; its preference stems from its visibility in yellow light during processing.
15. Additionally, green’s compatibility with optical calibration enhances instrument recognition, while being gentle on the eyes and environmentally friendly.
16. Over time, green PCBs have dominated the market, becoming the standard color due to these advantages.
