Printed circuit boards support electronic devices of all types and sizes. For example, many consumer products contain PCBs, including laptops, tablets, smartphones and smartwatches, as well as appliances, entertainment systems and IoT devices. PCBs also drive communication and navigation systems and are found in industrial and medical equipment, automobiles, aircraft and sea vessels.

Many of today's PCBs adhere to a high-density interconnect (HDI) design, which incorporates a higher wiring density than traditional PCBs. HDI circuit boards require less space and can accommodate more components. The design also makes it possible to create more compact PCBs, which weigh less and require fewer materials. The HDI design is well-suited for use cases where space is an important factor, such as smartphones, home appliances or medical implants.

A PCB can be single-layer, double-layer or multilayer. Single-layer PCBs are typically used for simple electronic devices such as home appliances, while multilayer PCBs tend to be built for more complex hardware, such as computer graphics cards and motherboards. Double-layer PCBs allow for greater density than single-layer PCBs and are used for electronic devices such as automotive dashboards or LED lighting, for example.

A PCB's layer count is commonly based on its number of conductive layers. However, a PCB also includes other types of layers, which are laminated together in alternating patterns of conductive and insulating material. Today's PCBs always contain the following four types of layers:

What is a circuit boardand how does it work

The PCB components connect to each other via traces, which facilitate communications between the components. The traces are created from the conductive layer through a process called etching, which removes all the copper from the conductive layer except what is needed for the traces.

PCB components use one of two methods to connect to the board: through-hole or surface-mount. Through-hole components have connecting wires (leads) that plug into holes in the board. The leads are soldered to the other side of the board. Surface-mount components are soldered directly to the same side of the board. Today's PCBs tend to favor surface-mount components because they require less space and are more efficient, although they're more difficult to assemble.

A printed circuit board (PCB) is a structure for assembling electronic components and their connections into a unified circuit that allows electrical current to pass between components. The PCB baseboard is typically made of a rigid nonconductive material, although it can also be built on a flexible base or on a base made up of both rigid and flexible materials. Electronic components such as diodes, inductors and transistors attach to the circuit board, and traces (electrical conduits) connect components.

A PCB is made up of a mix of these four types of layers. The mix and its organization varies depending on the PCB's purpose. A single-layer PCB includes one of each of these four layers. A double-layer PCB includes one substrate, but two of each of the other types of layers. A multilayer PCB will contain a mix of conductive and nonconductive layers, although the exact organization can vary. In some cases, a multilayer PCB might also use prepreg as a layer. Prepreg is a dielectric material that's sandwiched between two core layers or between core and conductor layers.
