Substrate: This is the base material of a PCB.The PCBA process always starts out with the most basic unit of the PCB: the base, which consists of several layers, and each one plays a significant role in the functionality of the final PCB. To help you better understand the PCBA process from start to finish, we've explained each step in detail below.
With each step of the process, a board manufacturer has both manual and automated options from which to choose. So how exactly are these devices made? The PCB assembly process is a simple one, consisting of several automated and manual steps. These functions range from the simple to the complex, and yet the size of PCBs can be smaller than a thumbnail. They run signals between these features, allowing the circuit board to function in a specifically designed way. The copper lines on bare board, called traces, electrically link connectors and components to each other. A PCB with components mounted on is called an assembled PCB and the manufacturing process is called PCB assembly or PCBA for short. An advanced circuit board won't be able to give its functionality until components are mounted on it. However, have you ever observed those boards with components solidly stuck on? Never regard them as just decorations of a PCB board. This solder mask is where that characteristic green color comes from. Made with fiberglass, copper lines and other metal parts, these boards are held together with epoxy and insulated with a solder mask. These are the small green chips covered in lines and copper parts you'll find at the heart of gutted electronic devices. Most people recognize printed circuit boards when they see them. At the heart of these electronics is the printed circuit board, also known as a PCB. Everything from our smart phones to our cars includes electronic components. Electronics are an integral part of our daily lives.
