Multilayer

Design with multiple layers to solve your most complex routing challenges

Multilayer

Multilayer flex circuits offer exceptional performance and reliability in situations where the circuit is exposed to excessive vibration or shock combined with frequent bending or folding. Multilayer technology allows high circuit density connections to be achieved in applications where one or two layers of conductors could not meet the required circuit packaging requirements. Additionally, multilayer flex circuits provide increased functionality with a smaller footprint.


Benefits of Multilayer

  • Multilayer high circuit density system can handle multiple conductive layers to save space
  • Layers range from one to eight in the flex area and up to 10 layers in the plated through hole areas
  • Flexible design parameters mean that circuits can accommodate EMI shielding layers, through-hole assembly, controlled impedance and other customer-specified electrical requirements
  • Incorporating unbonded areas will increase flexibility in bend regions
  • Ideal for the aerospace and defense markets
