Types Of Rigid Flex Circuit Boards And Its Use

by Delun kang writter

Rigid-flex circuit boards are the boards which are made by combining rigid and flexible board technologies in applications. Most rigid-flex board consists of multiple layers of flexible circuit bases depending upon the design applications.

Circuit boards and types

The Rigid-Flex Circuit Boards are flawlessly printed circuit boards which are designed keeping in mind the basic requirements of various industries. High-performance circuit board maintains good flex circuit stability and lifespan.

ü 4 Layer Rigid-Flex Circuit Board with ENIG finish: They are ideal for applications that involve ball grid arrays as well as surface mount devices. The basic materials used in its construction are polyimide as well as FR4. They help to improve the temperature resistant of the circuit board. They are available in various thicknesses as per the customer requirements.

ü 6 Layer Rigid-Flex Circuit Board: They are found in various custom and standard specifications. They are known to offer flexibility as well as design freedom to the engineers.

ü 8 Layer Rigid-Flex Circuit Board: They are known for their operational efficiency. They are used in various industrial as well as electronics applications. They help in improving the performance of the board in challenging conditions including UV and radiations, oils and harsh environments. They are vacuum packed which helps them while transportation.

ü 10 Layer Rigid-Flex Circuit Board with 4 layers flex circuit board: This is a 10 layered rigid-flex printed circuit board with 4 additional layers. This stable, rigid area is where the machine is mounted. The flexible layer that comes as a supplementary allow for a large flex surface as well as high frequency across the flexible area. These circuit boards are treated with immersion gold material.

ü 12 Layer Rigid-Flex Circuit Board: They are the improved PCB designs where multiple layers of rigid copper and flexible layers are organized one above the other which is specially designed to work with complex electronics. The 12 layer flex with heat sink help avoids overheating ensuring efficient performance of chips, connectors, traces and joints.

ü 14 Layer Rigid-Flex circuit Board: These circuits are used for applications which need high precision and tight tolerances. This circuit board comprises of flexible inner layers which are connected to a multi-layered flexible circuit. This rigid-flex circuits are equipped with a board internally or externally or both as per the requirement of the circuit.

Uses of this circuit boards

ü 14 layered rigid-flex circuit boards are used in telecommunication, computers, medical services and automobiles.

ü 12 layered rigid-flex circuit boards are used in surface finishing such as immersion gold, etc.

ü 6 layered rigid-flex circuit boards are used in power and lighting industries.

Applications and dimensions

Because of its specifications and applications it has gained popularity in most of the industries. Since they can design in three dimensions, rigid-flex design engineers can fold, twist, and roll to whatever desired shape they want. Some of the top manufacturers offer top-quality products in this regard.
