Test fixture and early warning system
A test fixture includes a fixed base for placing a module and probes. The fixed base defines threading needle holes, and the threading needle holes communicate with a surface of the fixed base adjacent to the module. The probes are connected with a tester and extend through the threading needle holes to contact with the module placed on the fixed base. The tester is capable of testing the module. When the module is disposed on the fixed base, the probes are directly connected with the module for testing, a gilded block between the module and the probes is omitted for improving a stability and an accuracy of test results. An early warning system is also disclosed.
