COPPER BAR WITH ADHESIVE FOR HEAT RADIATING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a copper bar with adhesive for heat radiating plate, which is not deformed (warped) even after its bonding to a lead frame. SOLUTION: A cooper bar with adhesive is bonded to a face that is not a plating face 2 in a lead frame 1 and is used as a heat radiating plate 6. A liquid crystal polymer whose coefficient of thermal expansion is 10 to 20 ppm/ deg.C is used as an adhesive 5.
