- Flexible electronics
Flexible electronics, also known as "flex circuits" or "flex circuit boards", is a
technologyfor assembling electronic circuits by mounting electronic devices on flexible high-performance plasticsubstrates, such as polyimideand PEEK Film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Flexible substrates have several advantages in many application:
* Tightly assembled electronic packages, where electrical connections are required in 3 axis, such as
* Electrical connections where the assembly is required to flex during its normal use, such as folding
cell phones(dynamic application).
* Electrical connections between sub-assemblies to replace wire harnesses, which are heavier and bulkier, such as in
* Electrical connections where board thickness or space constraints are driving factors.
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. In addition to
cameras, a common application of flex circuits is in computer keyboard manufacturing; most keyboards made today 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 micrometres.
solar cells have been developed for powering satellites. These cells are lightweight, can be rolled up for launch, and are easily deployable, making them a good match for the application.
