MANUFACTURING METHOD OF METAL COPPER CLAD LAMINATE FOR VOLTAGE TEST AND THE METAL CCL THEREOF

摘要

PURPOSE: A manufacturing method of a metal copper foil laminate plate for a voltage withstand test and a metal copper foil laminate plate manufactured by the same are provided to improve the accuracy and reliability of a voltage withstand test. CONSTITUTION: Metal copper foil laminate plates are consecutively inputted. An edge part of a copper foil layer(12) is removed at a specific width by a pair of cutting tools(20) or grinding tools installed on both sides of a feeding direction of metal copper foil laminate plates, and a copper foil eliminator(14) is formed. Metal copper foil laminates are rotated at 90 degrees or converted in a right angle direction. The edge part of the both sides copper foil layer of the metal copper foil laminate plates is removed at a specific width by a pair of cutting tools or grinding tools, and a copper foil eliminator is formed. The copper foil layer of four sides edge part of the metal copper foil laminate plates is all removed and a voltage withstand test is performed.
