 meaning its material content is higher than the single and double-sided PCBs. During manufacturing, multiple layers with a similar function like conductive are placed on the board, matching those carrying out another function like insulation. The PCB has a complex design due to the multiple layers. It is used to develop large objects in complex applications like data storage, medicine, and GPS technology.
4. Flexible PCB
Its number of layers varies depending on the type and consists of flexible material components. The materials, i.e., polyamide or polyester, allow it to bend and twist and take the base’s shape. Flexible PCBs are suitable for parts that require movement in different directions and come in handy in applications like electronics and automotive.
5. Rigid PCB
The PCB also has multiple layers, but it cannot be twisted or bent. Its material contents make it firm and solid hence difficult to break and last for an extended period. A base is used during installation, and the PCB retains its shape. Rigid PCBs are ideal for computer parts, for example, the CPU.
6. Flex rigid PCB
It’s an in-between of the rigid and flexible PCB. Its layers are both rigid and flexible, connected to form one board. Its mainly used in phones, cameras, and automobiles.
The different forms of PCBs serve various purposes in applications. In most cases, the layers determine their use example, those with multiple layers are suitable for complex objects. Seek guidance from a design expert to know which type is perfect for your need and its advantages. Also, consider the production cost since it varies from one to another.
