Splet25. avg. 2024 · Process monitoring During the PCB manufacturing process, there will usually be 2~3 100% tests, and then the defective PCBs will be repaired. By counting the percentage of broken, short circuit, and other insulation problems, analyzing the causes after heavy work, sorting out these data, and using quality control techniques to find out … SpletAfter environmental stress testing, microsection samples with press-fit pins fully inserted into the PCB are prepared and then visually analyzed and measured at key transverse and longitudinal locations in order to determine if any deformation has occurred. The drawing below illustrates specific locations for conducting measurements.
Overview of PCB/PCBA Reliability Testing and Failure Analysis
http://esmat.esa.int/ecss-q-st-70-11c.pdf SpletTo check the quality of PTH after the galvanic process we measure the Cu plating thickness of several holes on every production panel. On every production panel we include test coupons. From every production batch we select some coupons and make micro sections of the PTH to check the quality of the PTH in the final PCB. spectrum behavioral health virtual
