The copper roots narrow the line spacing, resulting in the printed board does not meet the requirements of Party A, and may even be rejected. Because the rejection will make the production cost of PCB greatly increased.
Laser marking can be a variety of characters, symbols and patterns, character size can be from millimeter to micron magnitude, which has a special significance for the anti-counterfeiting products.
The formation of residual film slagging indicates that the previous film removal process is not thorough. Poor film removal is often the result of the combination of edge film and electroplating.
The more links there are, the more likely there will be problems. This can be regarded as a very special aspect of the printed circuit production process.

The initial wiring phase uses a large 0.050 inch hole spacing in the SMD outlet and takes into account the type of package used. The subsequent wiring phase allows the holes to be positioned close to each other so that all tools achieve the highest spread
the growth rate is the passive components and PCB as the representative of the component plate. 5G substrates, such as soft boards, high-end high-speed materials and PCB, are comprehensively distributed, benefiting from the strong flexibility of 5G and th
The shortest and widest printed line permitted by the assembly process shall be used. For high frequency devices, the printed line of the power supply is equivalent to a small inductance, which will worsen the power supply noise and cause undesired coupli
Avoid running digital clock lines and high frequency analog signal lines near the power layer; otherwise, the noise from the power signal will be coupled to the sensitive analog signal.
PCB customization, BOM, material selection and other electronic industry supply chain solutions, one-stop to meet the comprehensive needs of small and medium-sized customers in the electronics industry.
Some customers have designed contour lines for Keep layer, Board layer, Top over layer and so on, and these contour lines do not coincide, which makes it difficult for PCB manufacturers to judge which contour line shall prevail.
