Abstract

The invention discloses a chip testing machine, a substrate, a test platform installed on the upper surface of the substrate, a drive bracket installed on the outside of the substrate, and a test probe assembly installed on the drive bracket and located above the test platform, the test probe assembly It includes: a body connected to the drive bracket, a support plate, a probe for contacting the chip to be tested, and a moving point contact probe. A cantilever is installed on one end of the support plate, and the moving point contact probe is installed on the other end. One side of the lower end surface of the body is provided with a static point contact probe located on the upper part of the dynamic point contact probe and corresponding to the static point contact probe. The end of the cantilever far away from the support plate is fixed with a probe seat on which the probe is installed; on the right side of the first pin shaft The center-of-mass moment of the support plate part, the cantilever, the probe seat and the probe is greater than the center-of-mass moment of the remaining part of the support plate and the moving point contact probe located on the left side of the first pin axis. The invention improves the stability, repeatability, comparability and consistency of detection data.

Description

technical field [0001] The invention relates to a chip testing machine, which belongs to the technical field of chip testing. Background technique [0002] In the production and testing process of lasers in the optical communication industry, before the COC aging process, it is also necessary to conduct a photoelectric performance test of a single laser chip (Laser Diode, LD), so that the performance of the laser chip (LD) can be screened before aging, and the performance Problematic lasers are picked out in advance, thereby improving the overall yield after COC burn-in. [0003] In the testing process of a single laser chip (LD) in optical communication, the stability of the probe plays a very important role. At least it will push the position or angle of the chip to shift. Once the position and angle of the chip change, it will directly affect the stability of subsequent test indicators and test efficiency, and the pressure stability of the test probe will also be directl...
