A straight line is not always the shortest route between two points in electronic products: Thanks to rigid-flex PCB architecture, circuits can be folded onto themselves with 180º bends—superimposed at minimum height—significantly shrinking product dimensions. [Read More]
One of our customers recently sent us a four-layer stackup that needed a little tweaking. We talked it over with our design engineers and came up with solutions and alternatives to all the issues at hand. It’s amazing how a few changes to your stackup design can ensure durability and manufacturability on your flex board. [Read More]

Flex printed circuits can provide several obvious advantages over conventional ribbon cables in certain applications. For example, a flex circuit can span between a board and a connector on a bulkhead several inches away at a right angle in the same plane as the board. That’s not feasible with a ribbon cable.
