Customer Reviews
Kevin, Received and tested the boards - thanks very much. These are perfect, exactly what we needed. rgds Rich

—— Rich Rickett

Ruth, I got the PCB today, and they are just perfect. Please stay a little patience, my next order is coming soon. Kind regards from Hamburg Olaf

—— Olaf Kühnhold

Hi Natalie. It was perfect, I attach some pictures for your reference. And I send you next 2 projects to budget. Thanks a lot again

—— Seba T.

Kevin, Thanks, they were perfectly made, and work well. As promised, here are the links for my latest project, using the PCBs you manufactured for me:

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 circuits.

 

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 dynamic 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

Thin-film switch, capacitive touch screen / panel, keypad FPC, laser head FPC,

General purpose LED soft light strip, mobile phone built-in antenna FPC Touch screen,

Telephone receiver / earphone FPC, contact belt of inkjet printer, Toy lamp strip,

LCD module, instrument panel, flexible flat cable, display backlight etc.
