FDC-biscuit straight welding connection structure

Abstract

The utility model relates to a kind of FDC-plate direct welding connection structure, comprising: the FDC body that is formed by die cutting process processing, including circuit layer, the upper insulating layer that is covered and connected on the upper surface of the circuit layer and the lower insulating layer that is covered and connected on the lower surface of the circuit layer, the side of the circuit layer is formed with the connecting portion extending outward;Plate, with the connecting portion is directly welded by laser welding mode;Wherein, one of the upper insulating layer and the lower insulating layer is provided with the welding window for partially exposing the connecting portion for the plate welding, another of the upper insulating layer and the lower insulating layer is provided with the heat dissipation window for partially exposing the connecting portion for welding heat dissipation.The utility model is formed by die cutting integrated FDC body and cooperates laser welding process, can realize direct welding with plate, avoids using more complex etching process, and does not need to be bridged by nickel sheet, greatly simplifies production difficulty, and saves process and material cost.
