PCBA Flying Probe Testing

PCBA Flying Probe Testing

PCBA Flying Probe Testing is a flexible, fixtureless electrical inspection method for Printed Circuit Board Assemblies that uses movable "flying" probes (instead of a fixed bed-of-nails fixture) to contact test points on the PCB and measure electrical parameters. Unlike ICT (which requires a custom

Two Causes of Electroplating Imperfections and How to Improve Them

　　With the rapid development of the PCB industry, PCBs are gradually moving towards high-precision fine lines, small hole diameters, and high aspect ratios (6:1-10:1), requiring 20-25µm of copper penetration at the holes. For boards with a line spacing of ≤4µm, electroplating imperfections are a com
