FPC (Flexible PCB ) Characteristics

RayMing Technology have more than 10 years Flexible PCB manufacturing experience , here we will instroduce FPC Characteristics , want to know Flex PCB at

The general FPC product type will be designed into the following representative types:

1. Single-sidedFlex PCB

Single-sided Flex PCB

2. Single-sided line double-sided assembly FPC

Single-sided line double-sided assembly FPC

3. Double-sided FPC

Double-sided FPC

4. Multi-layer FPC

 Multi-layer FPC

5. Rigid-flex PCB board

Rigid-flex PCB Board

6. Partially strengthened support soft board

Partially Strengthened Support Soft Board

Designers must have a clear understanding of the choice of these soft board types so as not to make inappropriate application choices. When the soft board structure type is selected, how to make good use of such soft board assembly characteristics to play the best soft board performance is the key to the success of the soft board product application.

General soft board application considerations include: functionality, cost, reliability, build efficiency, space applications, etc. A good FPC design can cost, improve functionality, and save space. These influencing factors should be considered at the same time.

For functional considerations such as circuit-type cable design, assuming a soft board to replace it can reduce the weight by 50%. Using soft boards to design electronics can have the following benefits.

1. Performance aspects

The components have relative motion requirements, and the soft board provides kinetic energy connections with high cycle flex life;The assembly of parts can be carried out in a plane and bent and assembled according to the product requirements;Can be restored to a flat state for maintenance;Can effectively improve the assembly efficiency;

2. Cost aspects

FPC can reduce the burden of traditional cable assembly, and may save assembly costs by 20% to 50%;It can fix errors in joints and mating directions, simplify inspection, debugging, and heavy work;

Compared with the cable, it can save complicated operations such as tangential cutting, stripping, and processing joints;

Compared to PCB dimensional stability, soft boards require more tolerance control such as process, tooling, and measurement. The flexible sheet of polythioimide resin material has a higher unit price than the hard board material of the same area, but the addition of the soft board may reduce the amount of hard board used and the connection of the cable. The use of soft boards makes product integration easier and reduces parts, terminals, contacts, and increases product reliability.
