What is a printed circuit board?

A printed circuit board is the heart of electronic devices. It usually consists of a substrate such as epoxy resin (e.g., FR4) coated with copper. Conductive tracks are created on this material by etching or milling, connecting the components to each other. These components are permanently attached to the board by soldering.

 

What are PCB used for?

Printed circuit boards can be found in almost all electronic devices:

• Computers and smartphones
• Household and entertainment devices
• Automotive technology and industrial equipment
• Medical technology and communications technology

They enable the compact, robust, and reliable implementation of electronic circuits.

How is a printed circuit board manufactured?

1. Circuit design using CAD software
2. Production of the board layout on a copper-clad substrate
3. Exposure of the printed circuit board with the board layout
4. Structuring of the conductor tracks by etching
5. Application of a protective layer
6. Drilling of through-plated holes
7. Testing of the finished printed circuit board

What types of PCB are there?
 

Printed circuit boards differ depending on their structure and intended use:

• Single-sided PCB: only one side has a copper layer and conductor tracks.
• Double-sided PCB: copper on both sides.
• Multilayer PCB: multiple layers on top of each other for complex applications
• Flexible PCB: bendable, for special installation situations
• Rigid-flex PCB: combination of rigid and flexible areas
   

Multilayer printed circuit boards are now standard in modern electronics, as they enable high packing density and complex interconnections in a small space
