Abstract

A transfer molded high lead count plastic semiconductor package is described. The packaged IC chip is mounted upon a suitable leadframe and the bonding pads wire bonded to the leadframe fingers. To avoid wire shorting, due to wire sweep during transfer molding, the wires are first coated with an insulative material.
