Rigid flex circuits have been used in the military and aerospace industries for more than 20 years.Rigid flex circuits combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control.

Flex Circuits – Not Always as Easy as They Seem

This little beauty has been a consistent runner for us.  At first glance, this seems to be an easy looking flex but don’t let its looks fool you; it is a challenging part to produce correctly.  In 2009 our customer came to us because of pricing and quality problems with another supplier.  This is not uncommon in the flex world as about 70% of our customers come to us because of quality issues they need resolved – and surprisingly they usually get a cost savings on most of their FLEX part numbers.

This customer is no easy walk in the park when it came to getting qualified either. At the bottom of this post you will see a copy of their vendor survey required just to be considered. We passed the survey, of course, with ease.

Again, while this flex board seems easy, and without giving away the secret sauce on why it is difficult and how it was built…it just points out that again that if we can do it for this customer, we can most likely do it for…

This PN has the following specifications:

  • 1 Layer flex board
  • Polyimide (Taliflex)
  • Adhesive
  • Immersion Gold
  • .13mm thick
  • 63.4*53.8 mm
