Abstract

The invention relates to a high-temperature tester for a lead frame. The high-temperature tester for the lead frame comprises a base. A cover board is disposed on the base. A groove fitting with the lead frame is disposed on the upper end face of the base. Two ends of the groove are provided with a feed inlet and a discharge outlet respectively. An elongated stirring hole is arranged in the cover board, is located right above the groove and corresponds to a small hole of the lead frame. A heating groove is arranged in the middle of the bottom of the base, and a heating bar is arranged in the heating groove. A pressure board is disposed on the lower portion of the heating bar and is connected with the base. A temperature measuring area is arranged on the cover board right above the heating bar, and a temperature tester is disposed in the temperature measuring area. Vent tubes are disposed on two sides of the base and are communicated with the groove. The high-temperature tester for the lead frame is applicable to high-temperature testing of the lead frame.

Description

technical field [0001] The invention relates to a lead frame high temperature testing device. Background technique [0002] During the production process of the lead frame, it must pass a high temperature test. After heating the lead frame to about 450°C, observe under a microscope whether there are oxidation spots on the surface of the lead frame. When heating the lead frame, nitrogen-hydrogen mixed gas needs to be introduced to protect the lead frame. However, it is necessary to meet the continuous test of the lead frame, to heat the lead frame, and to introduce nitrogen-hydrogen mixed gas. These are the difficulties in the design of the lead frame high-temperature test device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lead frame high-temperature testing device, which can not only satisfy the continuous test of the lead frame, but also heat the lead frame and protect the lead frame by injecting nitroge...
