Rigid Circuit Board FAQs

1.Where are rigid PCBs used?

Laptops, Tablets, Cell Phones, Heart Monitors, CAT Scans, MRI Systems, Aircraft Cockpit Instruments, Temperature Sensors, Control Tower Instruments, etc...

2.What are the characteristics of rigid PCB?

Rigid PCB is a regular PCB, it cannot be like Flexi PCB because rigid PCB cannot be twisted or folded into any shape because it has FR4 reinforcement which is very useful for increasing stiffness. Rigid PCBs are cheaper than flexible PCBs. They are traditional PCBs that are widely used in many electronic products.

3.What is the difference between rigid board and flexible board?

Rigid PCBs are circuit boards built on rigid base layers that cannot be bent, while flexible PCBs, also known as flex circuits, are built on flexible base layers that can be bent, twisted and folded.

4.What is a rigid circuit board?

A rigid PCB is a form of circuit board that is structurally strong and inflexible, so it cannot be bent or bent. They consist of several different layers, such as substrate layers, copper layers, solder mask layers and silkscreen layers, which are joined together by adhesive and heat.
