Method for manufacturing insulating sheet and method for manufacturing laminated plate clad with metal foil and printed circuit board thereof using the same

摘要

Insulation sheet production method and a metal-clad laminate and printed circuit board manufacturing method using the same are disclosed. Insulation sheet comprising the step of heating and pressing a thermoplastic resin layer on the step and the reinforcing base material to laminate the thermoplastic resin layer in the reinforcing base material is, it is possible to create near the insulating substrate to the thermal expansion coefficient of the semiconductor chip on the printed circuit board using the same it is possible to prevent bending or twisting, does not generate a stress to the connection member with the semiconductor chip and the printed circuit board, may have no cracks or peeling-off of the connection member, such as a lead-free solder. ; The reinforcing base material, the thermoplastic resin layer, heating and pressing, the organic fiber, the liquid crystal polyester resin
