Flex Circuit Board Introduction & PCB Types

A printed circuit board supports and connects electrical components using conductive tracks and pads from a copper sheet which are laminated between sheet layers of a non-conductive substrate.

About flex circuit board

The flex circuit board offers multiple possibilities for different types of products and designs. These circuit boards help you to find your favourite TV channels and adjust the volume in the remote. They are thin and light-weighted circuits. They are the replacements for the traditional ones. They help the electronic goods to be lighter and smaller when they design it. This will help them to make hassle-free movements.

Different types of Printed Circuit Boards

Single-sided Printed Circuit Board: These types of flex circuit board contain just one layer of base material. This base material is covered with a thin layer of metal usually copper as it has an excellent electrical conductor. It has an electronic component and a circuit on one side only. They are best for simple electronics. They are inexpensive and because of the design specifications, these circuit boards also used in special purposes.

Double sided Printed Circuit Board: Both the sides of these circuit board have metal conductive layer. The holes in this circuit board allow circuit on one side to connect the circuit on the other side. The double sided circuit board uses two methods for connecting them which are through hole technology and through surface mount technology. Through hole technology involves feeding tiny wires through the holes and soldering each of them to the circuit. In surface mounted technology, wires are not used. They allows more circuit to be made in a smaller space on a board which means the board can perform more functions usually at a lower rate and faster speed.

Multi layered Printed Circuit Board: This is also extension of double sided circuit board. They have several base layers and insulating materials separating the base layers. They saves even more space compared to the double sided. This multi layered board has different layers such as 4, 6, 8, and 10 depending on the demand of the product. They are generally used in computers or medical machinery or servers, etc.

Rigid Printed Circuit Board: They use a solid, inflexible base layers that keep the board from bending. A motherboard inside the computer is a best example of rigid printed circuit boards.

Flex- Printed Circuit Board: The base here is a flexible one. The materials allow the board to fit into shape that rigid boards cannot without damaging the circuit of the board. They can be single sided, double sided or multi layered.

Rigid- flex Printed Circuit Board: These board combine technology from both rigid and flexible circuit boards. A simple rigid flex circuit board comprises of rigid circuit boards that are attached to a flex circuit board.

Applications

Printed Circuit Board is used in computer, cameras, cell phones, bar code equipment, avionics, satellites, etc. If you want them for a specific task, it is always better to get them from the leading manufacturers.
