Description

Sliding burner socket and its operation method

The present invention relates to a burn-in socket and its operating method, in particular to a burn-in socket which can be opened and closed by a sliding mechanism and its opening and closing operation method.

In the current burn-in test, the performance of the chip is getting stronger and stronger, and the heat generated at high power is also higher. In order to meet the heat dissipation requirements of the burn-in socket, the usual method is to increase heat dissipation, such as configuring heat-dissipating fins, vapor chambers or heat pipes with good thermal conductivity in the cover of the burn-in socket, or even installing additional cooling fans or water cooling device. Since most of these heat dissipation methods are made of heavy metal structures and are usually arranged on the cover of the burn-in socket, the weight of the cover of the burn-in socket is usually greater than that of the burn-in base fixed to the burn-in carrier plate a lot of. When the cover of the burn-in socket is operated to move relative to the base of the burn-in socket, such as pivoting or sliding (horizontally sliding), especially when the overall center of gravity of the cover of the burn-in socket exceeds the base of the burn-in socket At this time, the cover of the burn-in socket will generate a large moment due to gravity, resulting in damage to the connection structure between the cover of the burn-in socket and the base of the burn-in socket. A damaged connection structure can increase additional friction, making it difficult for the user to operate the cover.
