PREHEATING APPARATUS FOR METAL CORE PCB SUBSTRATE AND SOLDERING METHOD ON THE SUBSTRATE USING IT

摘要

PURPOSE: A preheating device for a metal core PCB and a method for soldering the metal core PCB using the same are provided to efficiently solder the metal core PCB by preheating the metal core PCB before a soldering process. CONSTITUTION: A metal core(110) is inserted into a PCB. A preheating unit directly preheats the metal core by applying a current to the metal core. An insulation layer is formed on both sides of the metal core. A circuit layer(130) is formed on the outer side of the insulation layer.
