Product Details

General Profile

 


A breakdown of a flexible circuit shows that it consists of 3 basic
elements: copper foil, dielectric material and adhesive. Most of the
manufacturing proceses, i.e. imaging transfer, plating and etching ,
are quite similar to those used when producing plated-through boards.
However, there're differences due to the thin and floppy material used
in flexible cirucits.

 

 

 

Purpose of Flexible Circuits

 


1) to provide interconnections between printed circuit boards and other
    components.
2) to serve as three-dimensional substrates for the mounting of SMT
    components, e.g., in photographic and video cameras.
3) to establish interconnections capable of withstanding dynam flexing.
4) to form part of rigid-flex circuit boards.

 

 

 

Advantages

 


1) Flexibility
2) Volume decreases
3) Weight reduces
4) Consistency of SMD mounting
5) Reliability increases
6) Controllability of electrical design of parameters
7) Tin soldered overall on the FPC end
8) Material optional( PI, PET)
9) Low cost
10) Continuity of processing

 

 

 

Applications
