We list out our usual material and technological specification of Flexible Circuits & flex printed circuits (FPC) at the belowing table. Also you can view the facility tolerance of circuits.
If you would like some specail material, tighter tolerance or other requirements of flexible PCB (flex circuit board), you can Contact our stuff directly, we are at your service at anytime.
