MCCL FOR LOT TEST OF WITHSTANDING VOLTAGE, METHOD OF LOT TEST WITHSTANDING VOLTAGE BY USING THE SAME AND MANUFACTURING METHOD OF NORMAL DISCRIMINATED MCCL

摘要

PURPOSE: A metal copper clad laminate(MCCL) for a complete voltage withstanding test, a method for the complete voltage withstanding test of the MCCL using the same, and a method for manufacturing verified copper clad laminate are provided to prevent the occurrence of safety accidents a conductive foreign material is remained in the insulator of the MCCL. CONSTITUTION: An MCCL(100) is laminated structure of a metal plate(110), an insulator(120), and a first copper foil(130). The end of the first copper foil is spaced apart from the end of the insulator. If a conductive foreign material is remained in the insulator, the breakdown of an insulating layer is occurred. If the breakdown of the insulating layer is occurred, the MCCL is verified as a bad unit.
