NCAB GROUP

Flexible PCBs (Flex)

The demand for flexible PCBs is increasing in all business segments with especially strong demands from medical, military 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 in Asia that fit the technology and volume requirement. NCAB Group has a 5 M€ spend in this segment which makes us one of the strongest PCB suppliers for low volume flexible boards for medical and industrial applications.

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