Amphenol Trackwise Designs Limited

The longest flex circuit we’ve produced is a record-breaking 72m. This achievement surpassed our previous records of 52m in 2020 and 25m in 2019. While it’s possible to create even longer circuits, we haven’t been asked to do so yet. Our 72m flex circuit, made using polyimide base laminate with copper elements, showcases our patented ‘Improved Harness Technology’ (IHT).

The circuit plating tolerance across this 72m long circuit was +/-5um, showing the great process consistency that can be achieved using roll to roll manufacturing.

The majority of our FPCs are made with Polyimide substrate with copper conductors, however a wide array of other materials are available.  Substrates include PTFE, PEEK, PEI, PU, Polyester, LCP, and FR4.  For conductors you can also consider aluminium and nickel.

We also support a range of ROHS compliant finishes including immersion tin & silver, OSP, ENIG and ENEPIG

Our manufacturing parameters are 

• Minimum track – 0.050mm (0.002”)
• Minimum gap – 0.050mm (0.002”)
• Minimum drill – 0.3mm (0.012”) (Finished after plating)

Every project is different and it will very much depend on the availability of materials, and the processes required for your specific design.  Please give us a call so we can discuss your exact requirements.

We do have an AS9100D accredited design capability, however we are quite happy to work with your designers and advise on the nuances of designing for flex.   Please engage with us early in your design process so that we can assist with your design for manufacture.

As each flex is designed from scratch, it is possible to incorporate nearly all connectors currently available..  As part of the wider Amphenol group, we have access to a vast range of experience across many industries, so please feel free to get in contact with us for further advice.
