Abstract
A low-cost, high-performance, reliable micromirror package ( ) that replaces the ceramic substrate in conventional packages with a printed circuit board substrate ( ) and a molded plastic case ( ), and the cover glass with a window ( ), preferably an optically clear plastic window. The printed circuit board substrate ( ) allows for either external bond pads or flex cable connection of the micromirror package to the projector's motherboard. These packages support flexible snap-in, screw-in, ultrasonic plastic welding, or adhesive welding processes to overcome the high cost seam welding process of many conventional packages.
