Product Information:

  • Adhesiveless constructions are strongly recommended for all thin-core rigid-flex designs. Cross-section thickness of rigid or rigid-flex PWB's can be minimized using 1 and 2 mil core laminates
  • Flexible Silver Ink is an alternate material to achieve EMI/RFI shielding on flex circuits while maintaining high flexibility
  • Bookbinder technology can be employed to achieve a tight bend radius with multiple flex layers
  • Constantan is a copper-nickel alloy with properties that make it useful as a replacement for copper thermal stability is a concern.
