The method of judging the technical index of FFC PCB
lexible FFC flat circuit board, also known as "soft board", is a printed circuit made of flexible insulating substrate. Flexible FFC cabling circuit provides excellent electrical performance to meet the design requirements of smaller and higher density installations, also helps to reduce assembly procedures and enhance reliability. After we have assembled the flexible FFC wiring board, we need to carefully check whether there is any error in the circuit wiring before running. How to judge?1. Power on to observe the situation of the circuit board. This point means that we need to adjust the required power supply voltage value and make sure that there is no short circuit at the power supply end of the PCB circuit board before connecting the corresponding power supply to the PCB circuit.
2. Before power on test run, it is necessary to carefully check whether there is any error in the wiring of PCB circuit. According to the corresponding PCB schematic diagram, carry out the corresponding inspection step by step in a certain order.
3. In addition, it can also be judged by the index of the test instrument. After the static and dynamic debugging of flexible FFC wiring board is normal, at this time, it is necessary to test the circuit board, record the relevant test data, analyze the test data, and finally make the test conclusion.
