  • Compliancy tolerant pattern for circuit carrying substrate
    Patent number: 5166865
    Abstract: A circuit carrying substrate (108) accommodates circuit components (102) with different coefficients of expansion and contraction from that of the circuit carrying substrate (108). Beneath the components (102) a plurality of slots (104) are formed so as to minimize the effects of the differing coefficients of expansion and contraction.
    Type: Grant

  • Method and apparatus for EMI/RFI shielding an infrared energy reflow soldered device
    Patent number: 4838475
    Abstract: An EMI/RFI shield (10) comprises a box like structure formed of a metal integral member having a plurality of apertures (16) formed therethrough. The apertures (16) are of a size appropriate to substantially pass infrared energy (22) and to substantially block EMI/RFI energy (26). When placed on a substrate (18), infrared energy (22) can be utilized to reflow solder a device (19) encapsulated by the shield (10) to the substrate (18).

  • Housing for vibration sensitive circuits
    Patent number: 4736069
    Abstract: Disclosed is an improved housing being comprised of a substrate and a cover that is plated to provide RF shielding. The substrate and cover are constructed of a like material to keep the coefficients of vibration approximately identical. Preferably, the substrate and cover material are ceramic thereby providing a rigid structure that minimizes vibration degradation.
