How to test bare PCB board？
Test bare PCBs with flying probe, AOI, and impedance meters to catch hidden flaws early. Balance materials, tolerances, and layer count to control costs and prevent assembly failures.
What is PCB via stitching?
PCB via stitching creates parallel return paths to suppress EMI and boost signal integrity in high-speed designs, but overuse risks PCB fractures during manufacturing—balance is key.
