Abstract

The invention relates to a chip temperature testing device and a testing method. The chip temperature testing device comprises a high-low temperature host machine, a high-low temperature box which is communicated with the high-low temperature host machine through an air inlet pipe and an air return pipe, and a drying tower which is communicated with the high-low temperature box through a drying air pipe. Therefore, the chip temperature testing device has the following advantages: 1, the device is reasonable in design, simple in structure and totally practical; 2, the device can realize ideal testing conditions which are the same as that of a laboratory high-low temperature box, so that the device is enabled to be applied to batch production; and 3, the device is low in cost and energy consumption.

Description

technical field [0001] The invention relates to a testing device and a testing method, in particular to a chip temperature testing device and a testing method. Background technique [0002] The application of integrated circuit chips is becoming more and more extensive, and the test and production of some integrated circuit chips with special applications need to be carried out in a high and low temperature environment. At present, several large foreign test and sorting machine equipment companies have the manufacturing capacity of high and low temperature, especially low temperature -40 degree test and sorting, but most of them use liquid nitrogen refrigeration, which is expensive to use. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art; it provides a device for chip temperature test which can reach the same ideal test conditions as the laboratory high and low temperature box, so that it can be applied...
