  • Burrless castellation via process and product for plastic chip carrier
    Publication number: 20040141299
    Abstract: This invention incorporates a new process and structure for manufacturing castellation via in plastic chip carrier. It allows the creation of uniform side wall contacts in the shape of half-cylinders, devoid of any burrs and power dust particles, which when present in a plastic chip carrier, would prevent reliable electrical contacts by causing either short or open circuits. Thus the invention enables plastic chip carrier as a practical way of replacing traditional ceramic chip carriers.

  • Process and structure for manufacturing plastic chip carrier
    Patent number: 6675472
    Abstract: A process for forming a burrless castellation for a plastic chip carrier comprising forming one or more through holes in a substrate, plating the through holes with a metal to a thickness ranging from about 2 microns to about 6 microns, routing slots along the line extending through the through holes to produce half cylinder-shaped side-contact surfaces, and plating the half cylinder-shaped side-contact surfaces to a thickness in the range of 15 to 25 microns.
