  • Rotary clip for solder pallet
    Patent number: 5593040
    Abstract: A pallet holds one or more circuit boards for processing. A pallet opening for receiving the circuit board has grooves at one side to retain an edge of the circuit board and rotary clips at the other side to receive and hold the opposite edge of the board. Each clip is a disk which is mounted for rotation about a central axis and is constrained to two angular positions by a detent. A notch in the disk receives the circuit board when in one position and clamps the board against a seat when in the other position. The notch is deep enough to allow the board to be shifted laterally for alignment with test apparatus.

  • Circuit assembly encapsulated with polybutadiene urethane
    Patent number: 5185498
    Abstract: An acceleration sensor is packaged in an open can and encapsulated in an elastomeric polybutadiene compound which maintains its mechanical properties over a range of -40.degree. C. to 105.degree. C. and transmits acceleration to the sensor with a unity transfer function. The encapsulation material comprises about 90 to 100 pbw of polyol and about 20 pbw of isocyanate, the polyol consisting of at least 70% of hydroxy-polybutadiene. For enhanced adhesion a foaming agent and/or an epoxy is added to the mixture.
