Web5.3 The test specimen shall be placed between the con-tacts of the HiPot test equipment (see Figure 1). Start the HiPot sequence. 5.4 Upon completion of the test, the HiPot sequence should include the discharge of the test specimen. (Safety note: Larger test specimens, with high capacitance density, may take more time than expected to discharge.) WebHigh potential (HiPOT) testing is an electrostatic stress test that detects potential dielectric failures. It can be conducted as an AC voltage test or DC voltage test depending upon the type of power on which the PCB works. Quality PCB design begins with the selection of appropriate PCB materials
