Flex Circuits
There are many connectors and termination options that are manufactured specifically for use with flexible circuits and flat flexible cables. Zero insertion force (ZIF) connectors and insulation displacement connectors (Figure 1) are both good examples. They offer reliable and inexpensive ways to terminate a flexible circuit. At the same time virtually any connector that can […]
Ever since the introduction of circuit boards, they have been evolving. They started as single sided, graduating to double-sided with plated through holes. Shortly thereafter multilayer circuit boards were introduced. The evolution didn’t stop there. New substrates began to come to the market with improved electrical and mechanical properties allowing designers to create denser designs […]
Q: Why are flex circuits more expensive than comparable rigid PCBs? What are the major costs drivers? A: The reason that flex circuits cost materials used to fabricate the circuits. First more than comparable rigid PCBs stems mainly from the of all, flex materials (i.e., clad and unclad polyimide film with or without acrylic adhesive) […]
