Gerber Layout & Design Recommendations

Epec's 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, and ensure there are no IPC design standard violations. 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. For a more in-depth look, see our blog post on flex and rigid-flex bend capabilities.

  • 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. See our blog post on flex circuit polyimide coverlay and soldermask considerations for more information.

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

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
