More than double your design options by adding a second layer


Double-sided flex circuits provide the ability to access circuit traces from both the top and bottom sides of the circuit, which offers greater flexibility in design and functionality. When properly designed and utilized, double-sided flex circuits offer the same level of dynamic, repetitive flexing as a single-sided flex, but with a greater range of application uses due to its ability to carry more complex circuit layouts.

Flexible Printed CircuitsBenefits of Double-sided Flexible Printed Circuits

  • Wider circuit design parameters when compared to single-sided flex
  • Reduced assembly costs due to minimized interconnect errors
  • Dynamic flexing ability
  • Reduced packaging dimensions
  • Can mount all component types – through hole, surface mount, and wire bonding
