2.2 Testing the reliability of PCBs (1) Conduct solvent resistance testing to evaluate the acid and alkali resistance of the green oil. (2) Conduct ion contamination testing to assess the level of contamination on the board surface. Ion residues, which are often polar, may cause electrochemical effects on the PCB. (3) Conduct thermal stress testing to evaluate the heat resistance of the substrate and copper layers. (4) Conduct high voltage testing to check the PCB's ability to withstand voltage. (5) Conduct delamination testing to assess the heat resistance of the PCB substrate. (6) Conduct solderability testing to inspect the soldering performance of the surface conductors and through-holes on the printed board. (7) Conduct Tg value testing (glass transition temperature) to test the PCB's glass transition temperature (Tg) using a differential scanning calorimeter (DSC)
