CIRCUIT IMPRIME DIT LED AVEC COUPE EN FORME DE BOL ET PROCEDE DE FABRICATION

摘要

A method for manufacturing an LED circuit board with bowl like reflective cups12 includes the steps of combing a glass fiber layer 20 and a copper foil layer 25 to form a combining layer and attaching it to an upper surface of a copper substrate 10; drilling a plurality of penetrating holes 11 through the combining layer and the copper substrate; etching the copper foil; drilling the combining layer to form a plurality of cups; sandblasting; electroplating gold 30 to the copper foil layer of the combining layer for increasing electric conduction and heat dissipation; printing an insulating ink mask layer (or a paint) 40 on the upper surface of the gold layer; electroplating a plurality of metal joints 50 on the ink layer portions as electric joints; and removing parts of the insulating ink layer so as to expose the gold layer and baking the structure.
