ALGOR THERMAL, VIBRATION, AND SHOCK ANALYSES

Thermal, vibration, and shock analyses are performed with the aid of an Algor software program on all hi-reliability designs. Thermal analysis identifies hot spots and overall thermal performance, insuring that the thermal stress on the components is well within the intended limits. Mechanical shock and vibration analyses, performed early in the design phase, insures mechanical integrity for the intended application.
