What is rigid PCB?
A rigid circuit board is a traditional type of electronic board that’s used in a wide range of products. It’s very popular and can still be used in a variety of applications.
A rigid board is a type of circuit that is very solid and cannot be bent or flexed. It’s made up of various layers, such as a copper layer, a silk screen layer, a mask layer, and a substrate layer. These are joined together using heat and adhesive.
Unlike some types of circuit boards, rigid PCBs can be used in various forms. They can be molded into single or double sided, or even multi-layered. However, once they’ve been manufactured, they can’t be changed or modified.
What are the uses of rigid PCB?
Rigid PCBs are widely used in industrial equipment, communications, medical equipment, aerospace devices, such as
- mobile phones
- Control tower instrumentation
- Temperature sensors
- Aeroplane cockpit instrumentation
- MRI systems
- CAT scans
- Heart monitors
- GPS equipment
rigid PCB advantages
If you are looking for a flexible and cost-effective alternative to traditional PCBs, then rigid PCBs are a good choice. These are also more durable than other types of boards, and they have a higher circuit density.
PCBs are commonly used in various industries where components need to remain fixed in order to endure the high levels of stress and heat that they can experience.
What is the difference between rigid PCB and flex PCB?
When people think of a circuit board, they usually think of a rigid board. These are usually made of non-conductive materials and are designed to connect electrical components. The glass used in these types of boards provides a strong and flexible structure. A rigid circuit board also provides good thermal resistance and support for its components.
Although a flexible circuit board can feature conductive tracks, it’s mainly made of a flexible base material. This type of board can endure various types of vibrations and can also fold up into a variety of shapes. Due to its structural flexibility, flexible circuits are commonly used in electronics that are compact.
Although flexible circuits are typically more expensive than rigid ones, they can be used in smaller spaces, which leads to indirect savings. Unlike traditional solder masks, flexible PCBs are protected by a coverlay or overlay process. Since flexible circuits have to bend, they can be made with more flexible rolled annealed copper.
