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

Hi,
I have seen some SMT components laying on circuits on a sheet of plastic,
which can be folded and saves some space. 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.
Best regards,
Victor
