As technology becomes more advanced, multi-layer PCBs are becoming more common.  The complex functionality and smaller size of many of today's electronic devices necessitates the use of multiple layers in their circuit boards.  A range of devices across industries use multi-layer boards, especially those with several functions and more complex capabilities.

Multi-layer printed circuit boards show up in many computer components, including motherboards and servers.  Computerized devices from laptops and tablets to smartphones and smartwatches use these types of boards.  Smartphones typically require around 12 layers.  The systems that allow electronics like smartphones, laptops and GPS devices to function, such as cell phone towers and satellite technologies, also include multi-layer boards because of the advanced functionality they require.

Devices that are less complicated than smartphones and signal towers but too complex for a single-sided printed circuit board typically use between 4 to 8 layers.  Examples of these types of products include household items like microwaves and air conditioners, which increasingly utilize multi-layer technology.

Medical devices also often run on boards with more than three layers because of the reliability, small size and lightweight design they require.  Multi-layer printed circuit boards appear in X-ray machines, heart monitors, CAT scan equipment and many other applications.

The automotive and aerospace industries are also increasingly using electronic components that need to be both durable and lightweight, making this type of PCB a perfect fit.  These components must be able to withstand wear, heat and otherwise harsh conditions.  Onboard computers, GPS systems, engine sensors, headlight switches and more components utilize these boards.

PCBs with high numbers of layers are also standard in the industrial industry.  More and more industrial machines have computerized components and often come equipped with sensors, controls and other parts that require PCBs.  This equipment needs advanced functionality, reliability and durability due to the harsh conditions of many industrial facilities.

For similar reasons, multi-layer PCBs play a role in many military applications, weather analysis equipment, alarm systems, atomic accelerators and a multitude of other electronic equipment types.

PCBmanufacturer talk  Deciding Whether You Need Multi-Layer PCBs

To determine whether you need single-layer or multi-layer printed circuit boards, you need to consider the needs of your project and which type best meets them.   Ask yourself these five questions:

1.   What level of functionality do I need?
2.   What is the maximum size the board can be?
3.   Is durability a priority?
4.   What is my budget?
5.   How quickly do I need the PCBs?
