Abstract
A quad flat package integrated circuit (IC) device has alternating inner and outer leads that protrude from a package body. The inner leads are j-shaped leads and the outer leads are gull-wing shaped leads. The package body is formed such that it includes plastic lead webbings between adjacent leads, which help prevent metal particles from getting lodged between the leads and causing electrical shorts. The webbings are made of the same molding compound as the package body and are formed together with the package body.
