Gerber Layout & Design Recommendations

Epec technical engineering team offers full flex and rigid-flex circuit design services. During our application review and quoting process, we carefully examined specifications, materials and construction in order to minimize and eliminate any technical issues.

We also look for areas of opportunity for improving the design of your flex or rigid-flex circuit's reliability, functionality. Cost reductions are also identified to generate an accurate quote that is based on a manufacturable, reliable and cost effective design.

Radiused Corners within Flex Bend Areas

Having a radiused corner within and flex bend area reduces / eliminates stress concentrators and improves reliability.

  • Flex PCB Radiused Trace - Preferred Method
  • Flex PCB Radiused Trace - Preferred Acceptable
  • Flex PCB Radiused Trace - Method Not Allowed
    Not Allowed

Staggered Layer to Layer Trace Positioning

Staggering your designs layer to layer trace positioning eliminates the "I-Beam" effect which improves the flexibility and reliability of your flex circuit.

  • Staggered Layer to Layer Trace Positioning - Preferred
  • Staggered Layer to Layer Trace Positioning - Not Recommended
    Not Recommended

Fillets & Teardrops

Proper fillets and teardrops eliminate stress concentrations and improves the reliability of the flexible PCB.

Vias within Bend Areas

This is not recommended. Having vias within a bend area can cause a significant stress concentrator which may lead to breakage.

Stiffener & Coverlay Terminations

Proper stiffener and coverlay terminations prevents creation of significant stress concentrator within the flexible circuit board.

  • Stiffener and Coverlay Terminations - Required
  • Stiffener and Coverlay Terminations - Not Allowed
    Not Allowed
