A Printed Circuit Board (PCB) acts as the foundation of any electronic device. It is a slim, flat plate of insulating material that has thin metal tracks on it, interconnecting various electrical components. PCB boards can be produced using different techniques and materials. The quality of the PCB board can have a significant impact on the performance and durability of the final product.
To ensure a high-quality PCB board for your electronic device, it's important to consider several factors. These include the material quality, surface finish, thickness of the board, SMT patch processing, circuit design, and PCB assembly. By working with a reliable and professional PCB manufacturer that takes these factors into account, you can be confident that your PCB board will meet the required standards of quality. In conclusion, careful consideration of these factors is key to ensuring that you receive a top-notch PCB board for your electronic device.
1. The size and thickness of PCB board must be consistent with the specified size and thickness without deviation.There shall be no defect, deformation, fall off, scratch, open circuit, short circuit, oxidation white, yellow, etching unclean or excessive marks, and there shall be no stains, copper particles and other impurities on the surface.
2. Ink cover uniform gloss, no shedding, scratching, dew copper, offset, hanging plate and other phenomena.
3. Silk-screen printing symbols and letters are clear, without omissions and blurring, reverse printing, offset and other bad phenomena.
4. The carbon film shall not have defects, printing deviation, short circuit, open circuit, printing and other phenomena.
5. PCB bottom plate forming, there shall be no leakage, deviation, hole collapse, edge, plug hole, beer burst, beer reaction, crushing and other phenomena.
A reputable circuit board manufacturing facility will choose reliable ink brands and give significant attention to the printing and baking process. The ink is a permanent protective film that covers the PCB and shields the lines from being easily wiped or damaged. It also acts as an insulator, making sure there is no short circuit, and is heat-resistant and moisture-proof, thereby preventing solder from sticking to the lines and providing salt spray prevention.
For a dependable circuit board, the ink must be relatively thick, with a thickness of not less than 20μm, in line with the IPC standard. If the solder ink is too thin, it can expose the copper line. Facilities with a low-quality process may experience issues such as IC bridge shedding, ink foaming, oil shedding, and plug holes not being full and transparent.
