Introduction of Flexible PCB
Key words: Flexible PCB, flexible pcb prototype, flexible circuit board, flexible printed circuit, Flex rigid PCB, rigid flex, flexible circuits, flexible PCB board
Flex-circuits are a reliable alternative to conventional wiring. Not only do they improve connection reliability, they simplify assembly and improve component appearance. This reduces rework and trouble-shooting time. By eliminating bulky wires, flex-circuits provide a cleaner, neater appearance.
Flex-circuits offer the same advantages of a printed circuit board: repeat-ability, reliability, and high density. However, the most important attribute that has made designers adopt flex-circuit technology is the capability of the flex-circuit to assume three-dimensional configurations. Flex-circuits can flex during installation and maintenance, or in use. With a little experimentation and imagination, a flex-circuit can save up to 75% of the space and/or weight of conventional wiring.
Furthermore, a flex-circuit offers dependability of price and of product. Recurring costs are lower than many wire harnesses, and since a flex-circuit is more resistant to shock and vibration than a PCB, repair and replacement costs are less.
Below are some of the ways that a flex-circuit can solve your design/packaging problems.
*Replace hardboard/ribbon cable assemblies.*Replace multiple hardboards and connectors with a single flex-circuit or rigid-flex circuit.
*Control impedance with integral ground planes.
*Control EMI with solid or patterned shield layers.
*Surface mount components, then fold into tight areas.
*Feed electrical connections through gaps too narrow for round wires.
*Design circuit with exposed conductors for use with conductive elastomer keypads.
*Integrate heaters, temperature sensors, or wire-wound antenna coils into a flex-circuit.
*Specify pressure-sensitive conductive adhesive to attach circuit to cabinets or enclosures.
*Use flex-circuits as jumpers between hardboards.
*Replace tiny wires with easy-to-handle circuits.
*Buy circuits in panels for automated assembly – circuits can then be routed and clipped out singly.
*Use low thermally conductive flex materials and foils for electronic interface to super-cooled enclosures, or other environments with large internal/external temperature differences.
