Rigid Flex PCB

Rigid flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation.


Rigid Flex

A flexible circuit board, also known as a flex circuit board, is a special type of printed circuit board where the board has at least a portion that is bendable. A typical use case of flex circuits is referred to as FFC (flexible flat cable) and is used as a replacement of cable wires and connectors, in which case the flex circuit is designed without electronic components. Other common use includes components assembled on the flex circuit such as led strip and LCD panel interface.

The electronic circuit is designed on a flexible plastic substrate, usually polyimide film for its high heat resistance which makes it suitable for solder mounting components. In some cases, the polyester film may be used as substrate material, where heat resistance is not needed and no components are soldered on the board. Instead, the board is printed with an industrial printer capable of dispensing conductive ink such as silver ink or carbon ink onto the polyester substrate. Examples of use are touch sensors in computer keyboards for keypress detection.

Flex circuits are often used as connectors in various applications where flexibility, space savings, or production constraints limit the serviceability of rigid circuit boards or hand wiring.

A common application of flex circuits is in computer keyboards; most keyboards use flex circuits for the switch matrix. In LCD fabrication, glass is used as a substrate. If thin flexible plastic or metal foil is used as the substrate instead, the entire system can be flexible, as the film deposited on top of the substrate is usually very thin, on the order of a few micrometers.
