The layers of a Flex PCB are more or less the same as a Rigid PCB, with the addition of an overlay, or coverlay i.e. a lamination process used to encapsulate and protect the external circuitry of a flex circuit. This is similar to the solder mask layer in a rigid PCB. The coverlay film is a polyimide film which is coated with a thermoset adhesive. It protects the flexible circuit from damage. The coverlay is optional, but most flexible PCBs do use this.,lucky4d

The fabrication of flexible PCBs does cost more than rigid PCBs, however they have a number of advantages in certain applications and thus the cost can be justified. For example, they can replace bulky wiring in Satellites where space and weight are the main constraints for the designers. They are also in LED Strips, consumer electronics and a number of other applications.,haa tepok
