Rigid Flex PCB

Rigid-Flex Printed Circuit Boards (PCBs) combine the advantages of both rigid and flexible boards, offering added design flexibility. Flexible PCBs are employed to connect the rigid PCBs, reducing the necessity for connectors, subsequently minimizing losses and overall PCB weight. Rigid-Flex boards generally offer cost advantages compared to standalone flexible PCBs.

Flexible PCB

Flexible Printed Circuit Boards (PCBs) can be bent and shaped into different form factors while maintaining necessary functionality. Diverse substrates such as Polyamide (PI), PEEK (Polyether ether ketone), or transparent conductive polyester films are utilized in their manufacture.

These PCBs are well-suited for applications where space and weight are limited, although they typically incur higher costs compared to Rigid and Rigid-Flex PCBs.

Metal Core PCB

A Metal Core Printed Circuit Board (MCPCB), also referred to as a thermal PCB or metal backed PCB, utilizes a metal base for its heat spreader section. Typically composed of thick aluminum or copper, this metal layer covers one side of the PCB. The metal core may be positioned centrally or on the rear of the board. The primary function of an MCPCB’s core is to dissipate heat from vital board components towards less critical regions like the metal heatsink backing or metallic core. These base metals in the MCPCB serve as substitutes for FR4 or CEM3 boards
