FPC has become an important type of epoxy copper clad laminate with flexible function. The flexible copper clad laminate (FPC) based on epoxy resin is widely used because of its special function, and is becoming an important type of epoxy resin based copper clad laminate.
Development prospect of single sided FPC:
1. thickness. The thickness of single sided FPC must be more flexible and thinner.
2. Bending resistance. Bending is an inherent feature of single-sided FPC. In the future, single-sided FPC must be more resistant to bending.
3. price. At present, the price of single-sided FPC is much higher than that of PCB. If the price of FPC comes down, the market will be much wider.
4. Process level. In order to meet the requirements of many aspects, the process of single-sided FPC must be upgraded, and the minimum aperture, minimum linewidth/line spacing must meet higher requirements.
Double sided flexible printed circuit board
The double-sided flexible PCB has two conductive layers, between which there is a polyimide insulating layer. The outer side of the conductive layer may be exposed or have a cover, such as a copper pad. Layers are usually connected by electroplated through holes to meet the design and use function of flexibility, but other methods can also be used. The covering film can protect the single and double-sided wires and indicate the location of the components. Like single-sided flexible circuits, double-sided flexible PCBs can support other components, such as pins, connectors, and stiffeners.
