  • Publication number: 20070109758
    Abstract: Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.

  • Patent number: 6630247
    Abstract: A ceramic-metal composite that is tough and stiff has been prepared and is comprised of an inert ceramic (e.g., alumina) embedded and dispersed in a matrix comprised of a metal (e.g., aluminum), a reactive ceramic (e.g., boron carbide) and a reactive ceramic-metal reaction product (e.g., AlB2, Al4BC, Al3B48C2, AlB12, Al4C3, AlB24C4 or mixtures thereof) wherein grains of the inert ceramic have an average grain size greater than or equal to the average grain size of grains of the reactive ceramic. The ceramic-metal composite may be prepared by forming a mixture comprised of an inert ceramic powder (e.g., alumina) and a reactive ceramic powder (e.g., boron carbide), the inert ceramic powder having an average particle size equal to or greater than the average particle size of the reactive ceramic powder, forming the mixture into a porous body and consolidating the porous body in the presence of a metal (e.g., aluminum) to form the ceramic-metal composite.
