Three main types of printed circuit boards
PCBs are usually made of epoxy or other composite materials. It is used to physically support components and connect them electronically to circuits in real time.
In its simplest form, a PCB will consist of a thin layer of insulating material and a layer of copper foil that is bonded to an underlying substrate (made of epoxy, glass, or similar). The number of layers on a PCB depends on the purpose and application. Lines or surface marks on PCBs are created using chemical etching. These wires help current flow and connect the different components together.
There are different types of printed circuit boards or printed circuit boards. Manufacturers choose printed circuit boards based on the type of application. Here are some of the most common types of PCBs:
PCB Assembly Method
The process used to assemble circuit boards and their components is called circuit board assembly technology. Manufacturers use different installation methods based on material, cost, size, and other factors. Some of the most commonly used techniques include:
Surface Mount Components
Surface Mount Components (or Surface Mount Material, also known as SMT) is a method of attaching permanently mounted electronic components on a printed circuit board directly to the surface of a printed circuit board. The resulting circuit board is called a Surface Mount Device (SMD). This technique was originally called "paperback".
