Some introduction to FPC flexible circuit board design

FPC Flexible circuit board is also called fpc Soft plate , It is a kind of soft that can be bent PCB Circuit board , It is also vulnerable , It is easy to break if it is not designed properly . As far as design is concerned , Today I would like to introduce some information about FPC Some related knowledge points of flexible PCB design .

FPC The design width of flexible circuit board is the same as that of pin Line width 、 Line spacing and pin It's about numbers .Pin There are too many FPC It is natural to be wide , This is for a single panel , We can also replace the single panel with double-sided panels , Thereby reducing fpc Width .FPC The flexible board has good flexibility , Redesign fpc The length can be left with allowance , Therefore, it is not necessary to calculate with complete precision . It doesn't affect FPC Under the premise of performance ,FPC The appearance design is also very important , When designing the appearance , We need to FPC Flexible board and B/C Clearance between parts and through holes , In full satisfaction B/C Wall thickness of the piece 、 In the case of strength , Try to give FPC Leave more space on the circuit board , This is also a very important part of our design .

We were using the Pro/E Design FPC Soft board , Do not use part-solid modular , Use sheet metal modules . Why do you say that , Because in the sheet metal module ,FPC The soft board can make the most close to the real object fpc Appearance ,FPC It is easy to bend and flatten , Easy to modify , Can most realistically simulate FPC The theoretical real position in the via . 

​

The above is just fpc Some knowledge about the structure of flexible PCB design , There is no mention of some hardware related indicators , When we really do design, we need to combine the hardware to make the most perfect design .
