HEAT SINK AND MODULE STRUCTURE USING THE HEAT SINK

摘要

PROBLEM TO BE SOLVED: To provide a superior reliability and inexpensive module structure having high heat radiation properties. SOLUTION: A heat sink is made of a copper alloy having a Vickers hardness of at least 70 HV after heat treatment for 4 minutes at 630 deg.C. The module structure uses the heat sink and has a structure where a ceramic circuit board is integrated with the heat sink via a brazing material.
