Abstract:
A method and structure are provided for implementing enhanced reworkable strain relief packaging for electronic component interconnects. A plurality of custom strain relief pads is provided with a component footprint wiring layout on a component carrier or a component. The custom strain relief pads are disposed at component body perimeter locations. A solder mask is applied around these pad locations to provide a constrained area for a fusible surface coating. A fusible surface coating material is applied in the to the custom strain relief pads in the constrained area and then soldering of components is performed. Then a structural adhesive material is applied to the custom strain relief pad locations.
