Flexible printed circuit boards - our FPC processes
Flexible printed circuits (FPC) are the basis of our mechatronic products. The films used in FPC technology are usually around 25-75 microns thin and are flexible sheets of PET (polyester = polyethylene terephthalate), PEN (polyethylene naphthalate) or PI (polyimide) material that are laminated to copper sheets with a thicknesses of 18-105 microns. The copper conductor image is produced by an etching process in a highly economical roll-to -roll process. It is no problem for us to produce single layer circuits with a size of 100 cm x 50 cm. With our high-precision manufacturing processes, we can realize trace widths of down to 0.1 mm.
If required enmech can tin-plate the copper trace image, to provide an excellent surface for soldering processes. As an alternative to the copper etching process enmech also offers flexible PET or PEN printed circuit boards in silver ink (conductive paste) technology.
