Flex PCB

Release time: 23/10/2017

FLEX PCB Flex PCB can be defined as a patterned printed circuitry arrangement. It also refers to components which use flexible based materials that either have flexible coverlay or those that don’t. Components used in the fabrication for rigid printed circuit boards can equally be used in Flex PCB. This is possible if the board conforms to the desired flexible shape. Flex PCB is a day to day procedure used in common technologies and in particular, high end electronics use the concept.

Electronics like desktop printers and hard disk drives use this knowledge. Flex PCB is used in a wide area of technology ranging from; automotive, medical, communication, consumer electronics, transportation, military, aerospace and in industries. They are highly preferred in transport industry due to their capacity to withstand high vibrations. There are various types of Flex PBC; Double Sided and Multi-layer flex which are mostly used in high speed applications with a desire for flexibility. Double sided Flex PBC is designed in various shapes to meet the demand of the user. They can also be designed using “Bling and Buried Vias” with Plated through Holes. Secondly, there is the Heavy Copper Flex Circuit Boards and they can be coupled with a flexible and thin copper layer that is designed to carry heavy currents. Flex PBC has a number of benefits. It helps in the reduction of wiring errors. With the traditional cabling boards, it is common to have issues with the wires. Flex PBC provides room for high level of circuit density. It can carry heavy circuit with no setbacks. It eliminates mechanical connectors and provides range for more robust temperatures. Flex PBC gives a strong signal quality thus enhancing quality of the end result. This system provides an improved impedance control and reliability, lastly, Flex PBC reduces the weight and size of the board.

Each of the materials used in the development of Flex PBC must meet the demands that are aimed at making it better and long lasting. Its base is made of a polymer film that provides the foundation for a laminate. This base material acts as the foundation on which the whole PBC is built. For bonding, adhesives are used in the creation of a laminate. Different polymer families are used to help in the withstanding of high temperatures. A metal foil is used as a conductor and it creates the circuit paths. Copper foil is most common due to its friendly cost and high capacity in conducting currents. Flex PCB is what modern electronic technology is riding on
