Product Detail

Different Design Rules Apply to Rigid-Flex PCB Design

Flexible circuits always have bend lines that affect routing. Because of the potential for material stress, you cannot place components or vias close to the bend line.

And even when components are properly located, bending flex circuits places repeated mechanical stresses on surface-mount pads and through holes. Your team can reduce those stresses by using through-hole plating and by bolstering pad support with additional coverlay to anchor the pads.

As you design your trace routing, follow practices that reduce stress on your circuits. Use hatched polygons to maintain flexibility when carrying a power or ground plane on your flex circuit. You should use curved traces rather than 90° or 45° angles and use teardrop patterns to change trace widths.
