Design Guidelines

Key considerations for successful rigid-flex PCB design

Bend Area Design

  • Maintain minimum bend radius (10-100x material thickness)
  • Route traces perpendicular to bend line
  • Avoid placing vias in bend areas
  • Use curved traces instead of sharp corners

Transition Zones

  • Gradual transition between rigid and flex areas
  • Reinforce transition points with additional coverlay
  • Use tear stops at board edges
  • Consider mechanical stress relief

Layer Stackup

  • Symmetrical stackup for balanced construction
  • Consistent materials throughout stackup
  • Proper adhesive selection for bonding
  • Consider CTE matching between materials

Manufacturing Notes

  • Clearly mark rigid and flex areas
  • Specify stiffener requirements
  • Indicate bend direction and location
  • Include assembly instructions

FAQ

  • What certifications do PCB factories have?

    All of our products are IPC rated with ISO 14001; ISO 9001; CE; ROHS certificates, etc. Our products are widely used in communication, medical equipment, industrial control, power supply, consumer electronics and aerospace, automotive industry and other fields.

  • How many layers can your pcb rigid-flex boards do?

    Rigid zone: usually 4-20 layers (up to 30 layers), flexible zone: 1-8 layers (multi-layer flexible structure), can also do 6-12 layers of rigid-flex combination (e.g., 6 layers rigid + 2 layers flexible) typical structure of the board, the actual number of layers need to be verified by DFM simulation, more than 16 layers of the design need to be additionally assessed for the loss of yield (every additional 5 layers, the yield decreased by 8-12%).

  • Is it possible to copy the board? Can you provide the unit price of the batch afterward?

    We can copy the board, but we can't evaluate the batch quantity, and we can't offer the price directly, because we don't know the model and brand of the devices on the PCB board, and we need to give the corresponding price according to the later production process, the brand and model of the assembled electronic components, and the production quantity.

  • Rigid flex pcb quote

    Our pricing structure is transparent with no hidden fees. Our prices are among the most competitive in the world. In the case of PCBs, quotes can be made in as little as 10 minutes, based on the difficulty of the boards, the quoting time will be different.

  • Do you charge for shipping? How do you calculate it?

    Generally, we will ask the customer if he/she needs to quote the shipping price for his/her reference before quoting. If so, we will ask the courier company's price according to the address and zip code, and the weight of the product, and then quote the price.
