Single layer printed circuit board is the most basic type of PCB design. As the name suggests, a single-layer board is made with only one layer that includes 2 sides: one side is the conductor and the other one is for parts placement.
Single layer PCB is very suitable for different types of PCB testing as it’s easy to design, assemble and ensure the components are working as they are supposed to. Single layer will often be used in prototyping and testing types of circuit boards although it’s common that such boards will mass produce as well if the design is simple enough to fit the application needs.
If you need a quick solution for low-cost quick and easy types of PCB fabrication, a single-layer PCB board might be the right solution for your needs.
Double layer PCB (sometimes called double-sided or dual layer PCB) are considered popular types of circuit board when it comes to mass production of PCB designs. The Double layer PCB consists of two sides, top and bottom, that sandwich cooper, insulating materials, and other different types of PCB materials.
Whenever you are an experienced hardware engineer/designer, double layer PCB should get the work done on most occasions. A double layer is often considered the best choice when designing a brand new PCB project.
Multi-layer PCB refers to any other PCB that is above 2 layers threshold. Some complex designs require a lot of vias and information transfers, which will result in a multi-layer PCB design. Multi-layer PCB can go anywhere from 4 up to 16 layers on a single PCB.
High density interconnects, on in short, HDI stands for the type of circuit board that comes with a higher density of wires. HDI board has a limited amount of space which results in tight spaces and lines.
The technology used in the production of HDI boards allows amplification of the original PCB design but in smaller, lighter, and denser spaces. The process of placing components over an HDI board requires advanced PCBA and SMT technology due to the high precision requirements and tight surface space. Repairing such boards manually can be a difficult task for engineers due to the density of the HDI board.
High-frequency PCB boards are defined as types of PCB that operate in frequencies above 1GHz. There are multiple materials that can be used for pthe roduction of such boards such as PTFE (Polytetrafluoroethylene). This material is often called Teflon, in short. Most of the high-frequency PCB types and designs can reach a frequency beyond 5GHz. There are other types of materials such as FR4 (glass-reinforced epoxy) and PPO (polyphenylene oxide). Those types of materials can reach up to 10GHz when used correctly.
High-frequency PCB types are crucial for industrial and critical systems use, due to their ability to transmit high-frequency fast signals across multiple circuits. For consumer use, other options might be a better choice such as a double layer or multilayer PCB.
