Abstract

An electronic package which includes a flexible substrate, stiffener and chip. The chip is bonded to the substrate, which was secured to the stiffener. Strain relief means are utilized at various locations in the package to prevent problems (e.g., tape "wrinkling") associated with relatively large differences in coefficients of thermal expansion between the package's various elements.
