Abstract
An electronic panel assembly (EPA) includes one or more electronic devices with primary faces having electrical contacts, opposed rear faces and edges therebetween. The devices are mounted primary faces down in openings in a warp control sheet (WCS). Cured plastic encapsulation is formed at least between lateral edges of the devices and WCS openings. Undesirable panel warping during encapsulation is mitigated by choosing the WCS coefficient of thermal expansion (CTE) to be less than the encapsulation CTE. Thin film insulators and conductors couple electrical contacts on various devices to each other and to external terminals, thereby forming an integrated multi-device EPA.
