How high are we talking? 1000 Celsius? KIC Thermal Profiling double sided aluminum profiling tape. I have used at an extreme application of 240 to 300 degrees celsius for 18 minutes. With up to 30 passes with no visible degree of deterioration.

Excessive Time above Liquidus will cause a solder joint to become extremely brittle. Any shock or stress to the joint can lead to a failure.

Has anyone had good luck with the reflow on these extremely heavy bga's. This bga has 1517 balls and requires alot of heat because of the thickness of the part. Just wondering if anyone out there can help me.
