A cos aging test fixture and a cos aging test device

Abstract

The utility model provides a COS aging test fixture, include: pressure component, it includes pressure piece mounting plate, the front portion of pressure piece mounting plate is installed spring plunger, the rear portion of pressure piece mounting plate top is installed and bears the column, the conductive plate, first electrode block and second electrode block are provided in the front portion below of conductive plate, first electrode needle and second electrode needle are provided in the rear portion of conductive plate, bearing plate, bearing plate sets up in the front portion of conductive plate, and with first electrode block and second electrode block correspond, the lower end of spring plunger abuts against bearing plate, fixture bottom plate, bears the column and presses the rear portion of pressure piece mounting plate and reaches on fixture bottom plate, the middle position of the front portion of fixture bottom plate is used to install COS. Make COS aging test fixture in the stress of temperature rise in aging test process causes and can be buffered release, and the heat sink substrate of COS is not easy to break, and adopts the aging test device structure simple, easy operation of this COS aging test fixture, and the heat dissipation effect is good.
