PCBBUY Quality Control

· 70-minute electro-plating time to ensure the copper thickness of the drill hole and surface copper.

·Backlight test to ensure the adhesion of through-hole copper.

·The AOI tests ensure the pass rate of conductor trace.

·High-speed Flying Probe Tests ensure the qualified rate of the circuit boards.

·The solder mask is exposed by an LED parallel exposure machine, and the exposure uniformity is more than 90%.

·High precision laser text printing machine, ensure silkscreen clarity and accuracy.

·Use military-grade material to guarantee the quality from the source.
