NCAB GROUP

Multilayer PCBs (Multilayer)

Representing more than 60% of NCAB’s purchasing power, the multilayer PCB segment is by far our leading product. We buy more than 60M€ of multilayers boards each year, giving us substantial influence with our factories. We maintain more than a dozen local and off-shore factories to support this important segment from NPI through production volumes. We have developed a long standing relationship with these factories and have worked with most of them for well over 5 years. Our proven track record of high quality and on-time delivery performance highlights our dedication to customer satisfaction.

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