Victor: Flexible printed circuits have been around since the late 50's and have improved greatly with the advent of new materials such as adhesiveless polyimide film. The FPC can be soldered using all of the conventional methods available for rigid PCB's. In some instance the FPC should be palletized or rigidize for ease of assembly. There are various materials such as thin, bendable FR4, mylar, Nomex, teflon, polyimide, etc. As with rigid boards there are also different processes to add the conductors such as additive, subtractive, metal filled epoxy, etc. If you have further questions, I would be happy to help. Call 603-337-1691.

I also heard that cellular phone or camera uses this kind of circuit board due to the limited space available. My question is : how do they solder the components onto it? Normal reflow? Would it go through the 200C without damage? What is the material of it? Thank you very much.
