Types Of Circuit Board Material

Printed circuit board pcb material types and comparison by liyan gong 4 years ago.

Types of circuit board material.

It determines the pcb board performance and scope of application. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it. A printed circuit board pcb mechanically supports and electrically connects electrical or electronic components using conductive tracks pads and other features etched from one or more sheet layers of copper laminated onto and or between sheet layers of a non conductive substrate. While there are several types of pcb materials that go into a given board product reliability is ultimately what consumers and businesses are looking for in products that use circuit boards.

Pcb base material is an important part of pcb. When you first imagine a pcb you will probably form the image of a rigid pcb in mind. This type of circuit board makes use of solid inflexible and strong substrate material. The chip on board is a semiconductor assembly technology where the microchip is directly mounted on the board and electrically connected using wires.

Flex is short for flexibility in this printed circuit board type. The circuits are produced by a slight layer of conducting material deposited on the outside of an insulating board called the substrate. With the development of electronic technology pcb base material meet more. The board types above can be used to select the circuit board material best suited for your design.

Different forms of chip on board or cob are now used to make circuit boards instead of the conventional assembly using several components. As stated above there are a number of physical characteristics or properties that can be used to identify circuit board materials. A pcb printed circuit board or pwb printed wiring board is a complex circuitry of copper tracks on a heat resistant material called pcb substrate. The acronym of the printed circuit board is pcb it is a self contained board with interconnected electrical and electronic components found in various devices ranges from beepers to pagers radios radar and computer systems.

Of course it s also crucial that pcb board materials are strong enough to hold together even if a component accidentally gets dropped or knocked sideways. Fr 4 is the most widely used material in this category. Electronic components are soldered on this circuit board to control flow of electricity in a preset matter for the electronic device to work in a manner that it was designed for. Different products have different requirements on the pcb base material.

With all pcb material types the purpose is to conduct electricity and provide insulation between conducting layers of copper.
