I have seen this problem and identified the root cause as foreign material
or contamination.  Some common sources:  excessive mold release on molded
component packages, machining or plating chemicals on heatsinks, and the
worst news, self-inflicted fun from residual assembly process materials.

Subject:        [TN] Adhesives for Attaching Heat SInks to IC's

Does anyone have a specific adhesive for attaching aluminum heatsinks to
IC's? We're using Loctite 315, but are having dismal results (the heatsinks
keep falling off).
