- the inspection apparatus can be installed in a normal temperature environment and the temperature of the IC package to be inspected can be directly increased to inspect the high-temperature performance. Even if the electrode terminals of the IC package come into contact with the contact probes and heat conduction occurs, the temperature drop of the IC package can be suppressed. Without heating by a heating element, the same socket can be used to test the room temperature performance.
- the heating element may have insertion holes corresponding to the plurality of contact probes, and a metal wire at least partially threaded between the insertion holes.
