Flex circuit design - the basics

Flex circuits or FCBs (flex circuit boards) are interconnections of electrical components mounted on high-performance thermosetting substrates like polyimide or polyetheretherketone (PEEK) Film etc. These ductile plastic bases are the reasons behind the characteristic flexibility of flex circuit boards.

Flex circuit designs - the variety

Based on the levels of conductive and insulted interlayer's, there are five prominent varieties in which flex circuit design are segregated. They are,

1. Single layer flex boards
2. Double layer flex boards
3. Multilayer flex boards with single access hole
4. Multilayer flex boards with multiple access holes
5. Rigid flex boards

In addition to these prominent flex circuit design types, several modern manufacturers offer effective integrated design solutions that combine efficacies of all these varieties into one single unit. Many a modern manufacturers also develop rugged Flex coils that answer the problem of wiring errors.

Flex circuit design - the cost regulators

In flex circuit design, factors like number of access holes, interlayer's, plated through holes etc., play a major role in overall costing of a circuit design.
