AI Technical Summary

Technical Problem

In existing air-blowing temperature control devices, the heat of the temperature-controlled airflow is not fully utilized, and the heat of the test socket is quickly dissipated, resulting in poor temperature stability and affecting the accuracy and efficiency of chip testing.

Method used

An insulation cover is installed on the outside of the test seat to form an insulation chamber, allowing part of the temperature-controlled airflow to flow into the insulation chamber, thereby enhancing the temperature stability of the test seat and reusing the heat of the airflow.

Benefits of technology

It improves the temperature stability of the test socket, reduces energy waste, enhances temperature control performance and the accuracy and reliability of chip testing, and is suitable for synchronous temperature control of multiple test sockets.

Abstract

The utility model relates to a blowing temperature control device. The blowing temperature control device comprises a substrate, a test seat, an air inlet piece and a heat preservation cover. The test seat is arranged on the substrate, and an air flow channel is arranged in the test seat. The air inlet piece is arranged on the base plate, an air inlet channel is arranged in the air inlet piece, and the air inlet channel is communicated with the airflow channel so as to convey temperature control airflow into the airflow channel. The heat preservation cover is arranged on the outer side of the testing seat in a covering mode, and a heat preservation cavity for containing the testing seat is formed by the heat preservation cover. Wherein the heat preservation chamber is communicated with the airflow channel, so that at least part of the temperature control airflow flowing out of the airflow channel flows into the heat preservation chamber, and the test seat is in a heat preservation environment. According to the blowing temperature control device, the heat utilization rate of the temperature control airflow can be increased, and the temperature control performance can be improved.
