Problems solved by technology

However, in the conventional technology, since the printed circuit board 110 in a stable state is bent upwards, the needle mark width d2 may be less than 25 μm, thus causing the problem that the probe 171 is not easily inserted into the needle mark 113

Embodiment Construction

[0040] refer to Figure 4 , which shows the semiconductor tool of the present invention, which has a test head 100 and a wafer base 160 . The test head 100 has a test head body 130 , a first restraint 121 , a second restraint 122 , a printed circuit board 110 , a clamp 140 , a probe holder 170 and an adjustment device 180 . The first restraining member 121 and the second restraining member 122 clamp the printed circuit board 110 to limit the degree of deformation of the printed circuit board 110, and the connecting part 131 and the printed circuit board 110 pass through the positioning part 124 (this embodiment adopts ZIF zero plug-in force socket connection) to provide mutual fixation. The test head body 130 is connected to the printed circuit board 110 through the connecting portion 131 . The regulating device 180 protrudes into the test head body 130 , and guides the airflow into the first constraining part 121 through the heat dissipation part 123 to regulate the surface...

Abstract

The semiconductor machine bench comprises a printed circuit board with first and second surfaces, a heat source to stable provide heat for the first liquid near circuit board to heat the board, and a regulating device to control the temperature of first surface to under the second surface and make the board deformation achieve rapidly stable state.

Description

Technical field: [0001] The invention relates to a semiconductor machine, in particular to a wafer testing machine. Background technique: [0002] refer to Figure 1A It shows a test head 100 of a conventional wafer testing machine, which has a test head body 130 , a first constraint 121 , a second constraint 122 , a printed circuit board 110 , a clamp 140 and a probe holder 170 . The first restraining member 121 and the second restraining member 122 clamp the printed circuit board 110 to limit the degree of deformation of the printed circuit board 110, and the connecting part 131 and the printed circuit board 110 pass through the positioning part 124 (this embodiment adopts ZIF Connected by zero insertion force socket) to provide mutual fixation. The test head body 130 is connected to the printed circuit board 110 through the connecting portion 131 . The clamping part 140 clamps the printed circuit board 110 . The crystal base 160 is disposed under the test head 100 . T...
