The PCB Fabrication Assembly is a process in which the boards are produced and manufactured by an assembly company in various sizes and shapes. This method is standard for the manufacturing of several different varieties of these small devices. This is done through a combination of electronic and chemical processes, and these come assembled with other components like circuit boards, connectors and circuits, and resistors. There are various types of PCBs, and the three major types are single-sided PCB, double-sided PCB, and triple-sided PCB.

The smaller sized ones are usually for integration into small-sized circuit boards. The large-sized ones are typically used to manufacture automotive and electronics devices. For manufacturing a PCB, a hot-milling method is standard. In this method, the boards are first laid out using a hot-die tool made of metal sheet metal. The boards are then coated with a special coating that helps protect the device from damage and deterioration. This technique is the heat-tamping method.
