Abstract
A method for the assembly of an adhesively sealed tape package having base and cover components is provided. An electronic device is first bonded to the inner leads of a tape leadframe. The chip on tape is then disposed between the base component and the cover component and adhesively sealed to both. The electronic device and a portion of the inner leads are thereby encapsulated. In one embodiment the base and cover components are an aluminum base alloy having an anodization layer over at least those surfaces exposed to the external environment of the adhesive.
