3 Types of PCB (Printed Circuit Board)

• Multilayer PCBs

Multilayer PCB increases the density and complexity of PCB designs by increasing the number of layers beyond the top & bottom layers seen in a configuration of double-sided. With the accessibility of many layers in a multilayer printed circuit board configuration, multilayer PCBs let designers make very thick and highly compound designs.


• Rigid PCBs

They are known for having different number of layers and sides, PCBs also come in changing inflexibilities. Generally, people think of inflexible PCBs when they imagine a circuit board. Rigid printed circuit boards use a solid, rigid substrate material like fibreglass which prevents the board from twisting. A motherboard within the tower of a computer is the best example of an inflexible PCB.


• Flex PCBs

Generally, the substrate in a flex PCB is a flexible plastic. This fundamental material permits the board to fit into forms that inflexible boards cannot and to turn or shift during use without harming the circuits on the printed circuit board. Though flex boards are expensive to make when compared to the rigid PCBs, they come with a number of advantages. For example, they can restore heavy or bulky wiring in superior gear like satellites, where weight and space matter. Flex boards are known to come in three formats, single-sided, double-sided or multilayer formats.
