pad board separation | 23 March, 2006

Recently my company (graphic card suppliers) have experenced some pad to board separation under the processor. I have researched and find that a number of papers have been written about this, but they give no solution, Is anyone out there experencing the same defect? Any suggestions?

Lifted pads are almost always caused by pad to substrate adhesion likely degraded significantly after too much heat. Poorly trained operators armed with soldering irons can do this expertly.
