Tolerance of Flex Circuits Circuits

Tolerance of Flex Circuits

When you design your circuit board, you should consider manufacturing capability and tolerance, so that the facility can make your flex circuit without any question. Belowing table are normal tooling for tooling and Line Width and Space (L/S & LW).

If you would like tighter tolerance or other requirements of flexible PCB(flex circuit board), you can Contact our stuff directly, we are at your service at anytime.
