Supplier Quality Engineering audit enables identification of printed circuit boards coated with Entek organic solderability preservatives. Includes OSP verification, process line optimization, and consultation on other PCB final finish options based on application requirements. A composition analysis of the OSP-coated PCB is employed to confirm Entek OSP is being used by OEM. Review of PCB fabricator’s OSP process line, including chemistry (cleaning, topography enhancement, pre-coat, OSP), equipment, and operating parameters, is undertaken.
