The needle mold 31 and the button pressing device 32 are electrically connected to the testing motherboard 11. The needle mold 31 is used to contact the circuitry on the FPCA product, thereby connecting the testing motherboard 11 to the FPCA product. The button pressing device 32 is used to press the buttons on the FPCA product. The lifting device is fitted onto the testing body 1 and, together with the testing fixture 3, drives the testing fixture 3 to rise and fall.
[0032] In this invention, when performing functional testing on FPCA products, the technician first places the FPCA product to be tested onto the support fixture 2. Then, the technician drives the test fixture 3 to move downward using a lifting device, so that the pin mold 31 of the test fixture 3 contacts the circuit of the FPCA product. Next, the technician controls the test motherboard 11 to work by operating the operation button 13. The test motherboard 11 performs functional testing on the FPCA product according to the built-in program of the microcontroller 111, and the test results are displayed on the display screen 12. After the test is completed, the technician drives the test fixture 3 to move upward using the lifting device and removes the FPCA product.
[0033] As can be seen from the above, when performing functional tests, the stand-alone functional testing device of this utility model automatically tests the FPCA product through the built-in program of the microcontroller 111. Technicians do not need to perform corresponding programming, making it convenient to use. In addition, the test body 1 of this utility model has a power board 14 for power supply, which supplies power to the FPCA product.
