The rapid technical development of ultrashort laser systems is creating exciting possibilities for very precise localization of laser energy in time and space. These achievements have triggered novel laser applications based on nonlinear interaction processes. A promising three-dimensional microfabrication method that has recently attracted considerable attention is based on two-photon polymerization with ultrashort laser pulses.

Cost-effective assembly of custom-designed microelectromechanical systems (MEMS) for medium-caliber fuzes is challenging. In particular, the environment must have a setback acceleration exceeding 60,000g and centripetal acceleration of 9000g/mm out of center in a 30mm#2;173 projectile. In addition, the space available is very limited. The traditional approach is to mount the MEMS chip in a package that is then soldered to the printed circuit board (PCB). However, by mounting the MEMS chip directly to the PCB using conductive adhesive, we can increase the packaging density while reducing manufacturing cost.
