  • Patent number: 6655017
    Abstract: An electronic controller unit is formed of first and second base plates parallel to one another and spaced apart having a flexible substrate circuit board thereon with an intermediate portion of the circuit board extending between the two base plates. A connector is joined to the intermediate portion of the circuit board between the two base plates and is sealed to an edge of each base plate to form one side of the unit housing. A three-sided frame is joined to the other three sides of the two base plates to completely enclose the circuit board. The two major sides of the unit are formed by separate base plate pieces that are severed from an integral frame after the flexible circuit is bonded thereto. This allows the unit to be manufactured without bending of a rigid plate having the flexible circuit mounted thereto.
