Printed circuit boards (PCBs) are the least expensive and most common base for electronic products.
The type of PCB is determined primarily by its application, reliability and expected environmental exposures. As the world’s leading PCB and PCBA manufacturer, Huaxing can speak with great authority on all types of PCBs.
Before I share details about each, let’s review what a PCB is.
A printed circuit board or printed wiring board, or as I prefer to call it, a printed wiring/connection system board, is a flat surface that physically supports and connects electronic components. It has conductive pathways,or traces, and lands or pads for making electrical connections. Components such as capacitors, resistors and integrated circuits are mounted to the PCB,usually by soldering.
Here is a brief overview of the most common types.
These boards have a single layer of conductive material and are among the simplest and most cost-effective types. They are suitable for basic electronic functions.
These have circuits on both sides of the substrate and can accommodate more components than single-sided versions. Connections across layers can be made through either through-hole or surface mount technology, providing greater flexibility in design.
Consisting of three or more layers, these PCBs are designed for complex applications such as computers and other professional equipment. The multi-layer design allows for a higher density of components, which is ideal for advanced electronic needs.
Made with a flexible plastic substrate, these PCBs are used where bending or movement is required, such as in foldable devices or in applications where the board must conform to a specific shape.
Combining features of both rigid and flexible PCBs, these boards offer structural stability while retaining flexibility in designated areas, ideal for dynamic applications where both properties are needed.
Focusing on heat dissipation and structural rigidity, these PCBs are typically used in LED lighting and automotive applications where managing heat is crucial.
To help you choose the right type of PCB for your needs, consider the following table summarizing their key characteristics and typical applications:
| Type of PCB | Key Characteristics | Typical Applications |
| Single-Sided | One conductive layer, simple design | Consumer electronics, LEDs |
| Double-Sided | Two conductive layers, more complex | Industrial controls, UPS systems |
| Multilayer | High complexity, reduced size and weight | Computers, telecom equipment |
| Flexible | Bendable, lightweight | Wearables, mobile devices |
| Rigid-Flex | Combination of rigid and flex | Advanced digital cameras, drones |
| Aluminum Backed | Heat dissipation, rigidity | Power supplies, automotive |
Choosing the right type of PCB all depends on the application. How complicated is the board? How many lights do you want to light up at the same time? How much current are you running through the board? How much heat is it going to generate? How many input sources does it require? How many output signals does it require? I could go on and on with the number of different variables that you could use to pick what type of PCB is best for your application. That’s one reason you want to work with a company like Huaxing that does different types of PCBs every day for customers all over the world. We can assist you in selecting the type you need, the type that will give you the optimum performance and the best results in return.
An emerging technology within PCB manufacturing resolves this issue. When manufacturing these boards, although copper is placed over the entire board, onlythe copper on the pads where components attach remains at the end of the process.All other copper is etched away. One technique to achieve this is “multilinear capping,” in which copper is applied to the traces on the non-component-carryingsides of the PCB. Multiple PCB layers are created by stacking and laminating copper sheets, regardless of the specific thickness being used.
This method has revolutionized the industry, allowing for the creation of complex multi-layer boards with improved reliability. The use of copper for traces on the non-circuit-carrying sides enhances the board’s performance and durability. Such advancements in PCB technology have significantly contributed to improving the longevity and functionality of electronic devices.
Understanding the various types of PCBs is essential to know which one to manufacture or purchase. This gives you a good overview of the unique advantages each type of PCB offers.
