What are the types of fpc reinforcement?
Fpc is widely used in electronic products, but due to its low mechanical strength and easy cracking, it is necessary to fit reinforcing materials to strengthen the strength of FPC. So, do you know what types of fpc reinforcement are available? Today, the editor of PCB factory will take you to understand the three types of fpc reinforcement, please continue to look down for details:
1. PI reinforcement: tolerance can be controlled within +/- 0.03mm, high precision, high temperature resistance (130 degree Celsius-280 degree Celsius). PI reinforcement thickness: 0.075mm, 0.1mm, 0.125mm, 0.15mm, 0.175mm, 0.2mm, 0.225mm, 0.25mm.
2. Steel sheet reinforcement: manual assembly is required, the process is more complicated and the cost is higher. Steel sheet reinforcement thickness: 0.1mm, 0.2mm.
3. FR4 reinforcement: If the thickness is less than 0.1mm, the tolerance can be controlled within ±0.05mm. If the thickness is greater than 1.0mm, the tolerance is ±0.1mm. FR4 reinforcement thickness: 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 1.6mm.
The advantages and disadvantages of FPC reinforcement are that the PI tolerance is small and not very hard. The thicker thinking of FR4 has a larger tolerance. The steel sheet is hard and stable. Manual assembly is not easy to rework.
The above are some knowledge points about the type of fpc reinforcement, I hope it will be helpful to you.
