FAQ
BOND PLY product testing has been completed on various interface materials. These tests have demonstrated that improper surface wet-out is the single largest variable associated with maximizing bond strength and heat transfer. We have found that reducing the size of the interface pad to roughly 80% of the total interface area actually improves the overall bonding performance while offering significant improvements in total package cooling. Henkel offers three standard thicknesses for BERGQUIST® BOND PLY TBP 850, allowing each application to be optimized in three dimensions.
The answer to this varies from application to application, depending upon surface roughness and flatness. In general, pressure, temperature and time are the primary variables associated with increasing surface contact or wetout. Increasing the application time and/or pressure will significantly increase surface contact. Natural wet-out will continue to occur with BOND PLY materials. This inherent action often increases bond strength by more than two times within the first 24 hours
Adhesive performance on plastic packages is primarily a function of surface contact or wet-out. If surface contaminants such as plastic mold release oils are present, this will prevent contact and/or bonding to the surface. Make sure all surfaces are clean and dry prior to applying BOND PLY materials.
