A test fixture is a fixture product with functional testing. In order to save production costs, most of the current functional test fixtures use fully automatic solutions.
Another more general classification is based on the type of controller for functional testing. The control methods commonly used in functional testing include control methods, embedded control methods, etc. Among them, the control method can be regarded as a simple embedded control.
The characteristics of the embedded control mode of the test fixture are: fast test execution; simple and direct test operation; special circuits and programs are required for display and data output; the test plan is highly targeted; and the test software is easy to modify.
The function test of the test fixture is based on the different control modes. According to different operation methods, it can be divided into manual control function test, semi-automatic control function test and fully automatic control function test. The earliest functional tests were based on traditional manual and semi-automatic methods.
