Flex Circuit Polyimide Coverlay & Solder Mask Considerations

Written by Paul Tome
Posted on November 2, 2016 at 3:34 PM

Previously, we gave you the definition for flexible circuit coverlay. Now, we go into greater depth discussing the two primary options for encapsulating the external circuit layers of a flex circuit:  polyimide coverlay and flexible liquid photoimageable (LPI) solder mask. The two materials have very different capabilities and requirements.

Common Flex & Rigid-Flex PCB Constructions

Written by Paul Tome
Posted on May 27, 2016 at 10:30 AM

Flex and rigid-flex PCB constructions have many variations that allow for a wide range of applications and solutions. A significant difference to rigid PCB constructions is that uneven layer counts are allowed and frequently used. The primary reasons being reduced flex thickness, improved flexibility and reduced part cost.

Flex & Rigid-Flex Bend Capabilities

Written by Paul Tome
Posted on February 26, 2016 at 12:12 PM

Essential to any flex or rigid-flex printed circuit board (PCB) contruction is validation that your flex PCB design will meet your mechanical bend requirements. Minimum flex bend radius requirements were put in place so your design won't exceed the physical capabilities of copper circuitry, which would result in failed parts, long term reliability concerns, and several giant headaches.
