2OZ Flexible pcb FPC board with Carbon ink for keypad LCD display
Flexible Printed Circuit Board (abbr. FPCB) .
FPCB is minimization, slimness, high technology for whole digital products which are getting smaller, slimmer.
Compare with the rigid printed circuit board , FPCB has the following advantages
1. Light, thin, short, small, flexible structure, can be bent, curled, folded, and three-dimensional assembly, adapter can replace a lot of parts, easy to use maximum available space, making electronic products become more slim in appearance, widely used has a small, lightweight and mobile requirements of all kinds of electronic products.
2. High heat resistance, can produce higher density and finer pitch products to meet the high density interconnect between the components and the high stability requirements, so that a larger increase the quality of the signal output.
3. Can be wound transfer roller processing methods (Roll-to-Roll), easily automated, mass production,improve production efficiency.
