Questions tagged [production-testing]

Production Testing is sometimes called in-line testing. That is the PCB or assembly is completed but is only a sub-assembly. There can be many sub-assemblies to get to the final product. In-line testing is used to make sure sub-assemblies are fully functional per engineering standards, then sent to the stock room to be issued for the next assembly level. This procedure assures but does NOT guarantee that the final product will pass final testing.
