Expert has worked with process and material development that led to the Zontar process patent, a procedure for manufacturing high-performance, high-yield rigid-flex circuitry using adhesiveless flexible materials and rigid prepregs.

rigid-flex circuit board

Expert has developed several strip-line flexible circuits, working with design, materials choice, manufacturing technologies, tests, and test fixture design. He is the inventor of the "quilted" configuration for improved flexibility. He also worked on the development and tests for special connectors that control impedance in flexible circuits.

flexible circuit impedance control

Expert is the inventor, developer, and tester of printed circuit snap-action switches. The process is based on etching a single plane of spring metal, then forming it to create arrays of switches.
