摘要:
A film adhesive uses a hydrophobic polymer carrier instead of the conventional polyimide carrier to achieve high moisture resistance while maintaining other adhesive properties. For use in electronic packaging.
摘要:
A method for making an electronic component mechanically and electrically adhered to a substrate with a reworkable adhesive comprises applying the adhesive to either the electronic component or the substrate, contacting the electronic component and the substrate and curing the reworkable adhesive in situ.

This invention provides a process for applying a wafer level underfill comprising: providing a solvent-free hot-melt underfill composition; melting the underfill; applying the underfill in a uniform layer to the active side of a semiconductor wafer; returning the underfill to a solid state; optionally B-staging the underfill; optionally removing any excess underfill from the bumps on the wafer; and dicing the wafer into individual dies.

摘要:
An adhesive paste comprising liquid adhesive resin is partially curable to a tacky state at a temperature below the final cure temperature, and fully curable to a solid state at a temperature higher than used to reach the tacky state. In its tacky state, the adhesive paste will have sufficient strength to bond a silicon chip to a substrate with less than one kg force at room temperature. This ability is critical for thinner dies that may break with the use of greater force.
