What requirements should a high-quality FPC flexible circuit board meet?

May 26, 2022

FPC flexible circuit boards have different performance and quality due to different manufacturing processes or material selections. High-quality FPC flexible circuit boards should meet these requirements:

1. The shape is not deformed, the screw holes are not in place, and there is no error in the design;

2. It has strong environmental resistance and can maintain good performance in high temperature and high humidity environment;

3. The thickness, width and distance of the line meet the installation requirements, and there is no short circuit or open circuit;

4. There is no additional electromagnetic radiation, and the copper on the surface is not easy to fall off or be oxidized;

5. The mechanical properties, electrical properties and environmental properties meet the testing requirements and have high reliability.

Common test items for FPC flexible circuits include mechanical and assembly performance testing, appearance testing, dimensional testing, short circuit/open circuit testing, electrical performance testing, and environmental performance testing. With the assistance of electrical measurement methods and shrapnel microneedle modules, the quality can be improved, while meeting customer requirements, it can also reduce costs and improve productivity.

The shrapnel microneedle module can play a stable connection and conduction in the test of FPC flexible circuit, and is a bridge in the test transmission. Its service life can reach more than 20w times on average, and it can also maintain good performance in high-frequency tests; in large current transmission, it can conduct large currents in the range of 1-50A, and the overcurrent is stable without attenuation.

The FPC flexible circuit is light, thin and compact, and the shrapnel microneedle module is an integrated sheet-type design, which has strong adaptability in the field of small pitches, and can cope with pitch values between 0.15mm-0.4mm. , Continuous needle, effectively guarantee the stability of the test.

After the FPC flexible circuit passes the test, it can enter the next process. Faced with the problems in the test, it is necessary to solve them in a targeted manner in order to better improve the performance of the FPC flexible circuit.
