Application of flexible PCB
Types of flexible PCB
4. Substrate to generate double-sided board
Two layers of single-sided PI copper-clad plate materials are used to compress the board, supplemented by adhesive for a window opening at a specific position, so as to become a double-sided conductor circuit board with a two-layer separated structure in a local area to achieve a circuit board with high flexural performance in the stratified area.
(1) Single sided board
To form a single layer PCB board, the single-sided PI copper clad plate is used to form a flexible circuit board with a single layer of conductors by covering it with a protective film after the circuit is completed.
(2) Ordinary double sided board
For double sided printed circuit boards, after the double-sided circuit is completed with double-sided PI copper clad plate, the protective films are added on both sides to make a circuit board with double-layer conductors.
(3) Single sided board generated by substrate
A pure copper foil material is used in the circuit manufacturing process where a protective film is added to each side of the PCB to make a circuit board with only a single layer of conductors which, however, are exposed on both sides of the PCB.
(4) Double sided board generated by substrate
Two single-sided copper PI boards are compressed with a bonding adhesive at a specific location to form a double-sided conductor board with a lamination in one local area and a separation of the two layers in other local area to achieve a board with high flexural properties in the layered area.
Advantages of flexible PCB:
Good heat dissipation and excellent solderability, easy assembly and connection and low overall cost. That's why you would consider flex PCB when you buy the PCB board.
The base material is mainly polyimide copper clad laminate, which has high heat resistance and good dimensional stability. It can be pressed with a cover film with mechanical protection and good electrical insulation properties to form the final product.
The functions of flexible PCB can be divided into four types, namely lead line, printed circuit, connector and integration of function, the use of which covers computers, computer peripheral auxiliary systems, consumer electrical appliances and automobiles.
