FAQ

How are project parameters confirmed?
  • Project-specific manufacturability review against fabrication data and acceptance requirements.
Which surface finishes can be reviewed?
  • Finish, supply scope and acceptance criteria confirmed in project documents.

Process control points

  • Review rigid-flex stack-up and press sequence to surface bond-region void/delam risks early
  • Align flex coverlay/openings with rigid solder-mask boundaries
  • Confirm outline and depth-control/milling margins at the transition

Rigid-flex inspection focus

  • Inner & outer layer 100% AOI
  • Flying probe for prototypes; fixture test for volume
  • ENIG nickel/gold thickness via XRF
  • Impedance boards verified with TDR coupons
  • Multilayer X-ray registration; microsection sampling for stack-up
  • Delivery yield 99.8%; scrap controlled below 0.3%
  • Transition-zone microsection sampling
  • Flex outline and coverlay registration checks

Project inputs & review

  • Rigid/flex layer counts and full stack-up
  • Transition, coverlay, stiffener and bend notes
  • Material, finish, quantity and acceptance criteria
