Description
Technical Field
[0001] The present invention relates to the field of chip detection, and in particular to a lifting type chip detection device and method. Background Art
[0002] In the field of chip detection, in the existing chip detection equipment, the chip is generally turned on by a probe module during chip detection. Specifically, after the chip reaches the preset position, the probe module needs to drop a certain distance to contact the electrode of the chip. During the entire chip detection process, the probe module needs to be lifted and lowered back and forth. This type of chip detection prevents the structure of the probe module from being complex and occupying a large space. Due to the limited internal space of the detection equipment and the chip size and other conditions, the existing chip detection equipment can only use a small number of probe modules, which leads to a limited number of chips that can be detected at the same time, seriously affecting the chip detection efficiency; and the overly complex structure will lead to high equipment costs, difficulties in equipment installation and debugging, and other problems.
