Use professional tools to assess the appearance of the circuit board. This includes examining the dimensional characteristics of the board, such as size, thickness, aperture and pattern accuracy, wire width and spacing, and ring width. Additionally, check the ink color on the outer layer. A lack of brightness in the color may indicate insufficient ink coverage, potentially compromising the board's quality. It's also important to inspect the pad solder joints, surface defects, under-surface defects, wire defects, hole characteristics, and abnormal identifications.

How to identify a good circuit board?

Evaluate the quality of the PCB board based on its specification requirements. This involves ensuring that the board meets electrical testing requirements after SMT patch installation, passes machine tests without abnormal heating, or open or short circuits, and maintains the integrity of the copper skin and wire surfaces. The board should also exhibit no additional electromagnetic radiation and should withstand high temperatures, humidity, and special environments.

For PCB proofing, customization, and manufacturing, it's crucial to collaborate with a reputable PCB factory. Manufacturers like Benqiang Circuit are equipped with advanced production testing equipment and a comprehensive quality control system to ensure the best board quality.
