Description

FCT functional test tool

Technical Field

The utility model relates to a tester field especially relates to a FCT functional test tool.

Background

The function test can be divided into a manual control function test, a semi-automatic control function test and a full-automatic control function test according to different control modes. The earliest functional tests were mainly manual and semi-automatic. For some simple functional tests of the board under test, we sometimes use manual or semi-automatic test schemes based on simplifying the design and reducing the manufacturing cost. With the development of science and technology, in order to save production cost, most of the functional tests use a fully automatic scheme. In the existing equipment on the market, the design of the carrier plate and the pressure plate of the tester needs to be advanced in a plurality of unreasonable places, so that the whole operation engineering cannot be more efficient and reasonable.
