Removable polyurethane encapsulants. I. Formulation and long term considerations

Conference ·
OSTI ID:6193539
A solvent was developed for removable encapsulants and to evaluate their long term properties. These materials were developed to provide a component rework capability so that sophisticated electronic packages can be repaired without discarding the entire and often costly assembly. Encapsulants which are crosslinked such as epoxies and silicones are difficult to remove either by mechanical means or by solvent attack. The newly developed removable encapsulants are linear polyurethanes which can be dissolved in appropriate solvents with minimal damage to components.
