  • Patent number: 6242281
    Abstract: Leadless plastic chip carriers are formed from a matrix of lead frames provided in a section of a metal strip. Each lead frame in the matrix includes a die-attach pad and multiple leads disposed in close proximity to the die-attach pad. After a semiconductor die is attached to each of the die-attach pad and wire-bonded, the leadless plastic chip carriers are formed by providing a plastic encapsulation which exposes the bottom sides of the die-attach pad and the leads. The bottom sides of the leads serve as solder pads to be used for attaching the leadless plastic chip carrier to a printed circuit board.
