Abstract

The invention discloses a cooling test assembly unit and aging cooling equipment, and relates to the technical field of chip test.The test assembly unit comprises a box body, a cover plate, a cooling assembly, a protection plate and an electric connection assembly, the box body is a sealed cavity with an opening in one side, and the cover plate is hinged to the opening side of the box body to achieve opening and closing of the opening; the cooling assembly is mounted on the inner side of the sealing cavity; the protection plate is assembled above the cooling assembly, and a gap for assembling a to-be-detected piece is reserved between the bottom surface of the protection plate and the top surface of the cooling assembly; the electric connection assembly is installed on the side surface of the cooling assembly and is connected and conducted with the to-be-detected piece. The aging cooling equipment comprises the cooling test assembly unit. The technical problem that in the prior art, aging equipment cannot meet the aging test requirement of a high-power optical chip is solved.

Description

technical field [0001] The invention relates to the technical field of chip testing, in particular to a cooling test assembly unit and aging cooling equipment. Background technique [0002] Chip aging test is an electrical stress test method that uses voltage, high temperature or low temperature to accelerate the electrical failure of the device. The aging process basically simulates the entire life of the chip, because the electrical excitation applied during the aging process reflects the chip's working state. bad situation. [0003] Burn-in testing can be used as a test of device reliability or as a production window to discover early failures of devices. At present, the aging equipment on the market is usually aimed at the aging test of the high temperature environment, and cannot meet the aging test of the low temperature environment; When testing high-power optical chips, high-power optical chips are prone to light exposure due to long aging time. At the same time, l...
