CSP product side test fixture

Abstract

The utility model relates to test fixture technical field especially, more particularly to a CSP product side test fixture, including base, be equipped with the step groove on the base, and the lateral wall of step groove is solid equipped with the circuit board, the surface solid of circuit board is equipped with the positive and negative pole, and is equipped with a plurality of equidistance distribution's negative pressure hole between positive and negative pole, and negative pressure hole opens in the circuit board, and the position of step groove bottom is close to the circuit board and is installed two symmetrical setting's positioning assembly, the inside of base is equipped with negative pressure chamber, and one end of negative pressure chamber is equipped with the communicating groove, this CSP product side test fixture has solved the problem that traditional front test fixture cannot carry out side light emitting test to 0603 side light emitting LED, and when testing, can through vacuum adsorption effect firmly adsorb 0603 side light emitting LED on the circuit board, ensure that the positive and negative pole can be in stable contact with it, can avoid the test interruption problem caused by product movement or slide in the test process.
