Soldering die to heatsinks

2017/2/2 6:06:09

Currently I am in the buisness of soldering bare die to the top surface of a copper heat sink. Is any one else have some exprience in this process that can help. We heat a copper slug through a contolled atmosphere, place a preform then a bare die. Problems: voiding, poor wetting, TCE mismatch.
