Flexible PCBs (Flex)

The demand for flexible PCBs is increasing in all business segments with especially strong demands from medical, defense and industrial markets. Since the volumes normally are quite small for these segments, NCAB works with a number of HMLV (high-mix, low-volume) factories that fit the technology and volume requirement.

Please contact your local NCAB Group company if you need further information or assistance, we are happy to help you.
