Flexible PCBs

FPC (Flexible Printed Circuit) technology, also known as flexible PCB technology, is constantly evolving and finding use in the major electronics markets, including consumer, automotive, electro-medical, wearable, telecommunications, and aerospace. The traditional methods of connecting various components of the same circuit or of other electronic devices have been completely transformed by the invention of flexible PCBs. The solution based on flexible PCBs allows for a significant decrease in space, weight, and prices when compared to an equal solution based on rigid PCBs because of the connection's flexibility, compactness, and high density of electrical connections that may be obtained.

In numerous applications, flexible printed circuits have taken the place of various forms of wiring, a lot of which was done manually, bringing down the overall cost of electrical wiring by up to 70%. Flexible films and thin layers of conductive material, which can be directly attached to by soldering or conductive adhesive, serve as the heart of an FPC by making the electrical connection in place of conventional wires (consider, for instance, the connection between a microcontroller board and an LCD or OLED display).

FPCs can bend and flex because they are flexible, giving designers and operators of applications more freedom. Standard rigid circuits do not enable the ability of flexible circuits to adapt to small or oddly shaped environments. Flexible circuits also have the benefit of taking up less room, which eases the burden on the motherboard of the application. The amount of heat that must be dispersed is reduced because to better thermal management made possible by making the best use of the available areas.

Flexible printed circuits can also be more dependable and durable than rigid printed circuit boards, particularly in applications where the circuits are continuously vibrated and put under mechanical stress.Flexible printed circuits, which feature extremely low weight and thickness along with high mechanical resistance, resistance to high temperatures and atmospheric agents, as well as good electromagnetic immunity, replace the conventional interconnection techniques based on soldered wires and hand-wired connectors (EMI). In addition to being continuously subjected to mechanical loads and vibrations, all of these equipment demand a dependable connection in all vehicle operating situations. Flexible printed circuits in the automotive industry promise durability, longer lifespan, and have little to no maintenance requirements.
