Abstract: The present invention provides an assembly for protecting automotive electronics. The assembly includes a circuit board, a cover, and a metal housing. The metal housing is disposed over and around the circuit board. The cover and metal housing are crimped together to create a seal that protects the circuit board inside the metal housing and attaches the cover to the metal housing.

Abstract: The present invention involves a device for detecting a condition of a flowing fluid within a vehicle having reduced sulfur ingress. The device includes a base plate having a receiving surface and a circumferential edge and a printed circuit board disposed on the receiving surface of the base plate. The device further includes a housing having peripheral side walls attaching to the receiving surface adjacent the circumferential edge to define a peripheral interface enclosing the printed circuit board within the housing. The device further includes an adhesive material disposed at the interface to adhere the housing to the base plate. The adhesive material has a predetermined thermal expansion coefficient and a predetermined elastic modulus to reduce fluid ingress through the interface and to accommodate thermal expansions of the base plate and the housing.

Abstract: A method 10 for making multi-layer electronic circuit boards having metallized apertures 34, 36 which may be selectively and electrically grounded or isolated from an electrical ground plane.

Abstract: Disclosed are improved laminates useful in the manufacture of multi-layer printed wiring boards (MLPWB) and laminates. Such improved composites contain at least one layer which is formed from a liquid crystal polymer selected from the group consisting of poly(para-phenylene benzobisthiazole), poly(paraphenylene benzobisoxazole), poly(2,5-benzothiazole), poly(2,5-benzoxazole), and mixtures thereof. The presently preferred liquid crystal polymer comprises poly(para-phenylene benzobisthiazole). The negative coefficient of thermal expansion and high modulus of elasticity of the liquid crystal polymers enable a laminate and MLPWB to be manufactured therefrom having a tailored coefficient of thermal expansion, broadly ranging from about 0 to 15 ppm/.degree. C. MLPWBs constructed of polymeric core layers also are possible utilizing the preferred liquid crystal polymers of the present invention.
