ABSTRACT:
A method of manufacturing a transducer having a leaf spring cantilever beam with a strain gauge bonded to each side thereof by a layer of glass. Either one or both strain gauges and one or both glass layers are bonded simultaneously. The assembly is heated and a voltage applied to complete all bonds without removing it from the oven. The simultaneous bonding without oven removal doubles or quadruples production and unexpectedly has the dual function of increasing yield by over one-third based upon matched gauge resistance and strength requirements.
