Applications For Electronic PCB Assembly
Electronic products are an integral part of our daily lives. Everything from our smartphones to our cars contains electronic components. At the heart of these electronic products is the printed circuit board, also known as the PCB
Most people recognize printed circuit boards when they see them. These are small green chips covered in wiring and copper components that you can find in the center of destroyed electronic devices. The boards are made of fiberglass, copper wire and other metal components, held together with epoxy and insulated with solder mask. This solder mask is the source of the characteristic green color.
But have you ever looked at a circuit board where the components are firmly glued to the board? Never think of them as mere decorations on your PCB board. Advanced circuit boards can only perform their functions if components are installed on them. A PCB loaded with components is called an assembled PCB, and its manufacturing process is called PCB assembly or PCBA for short. Copper wires on the bare board, called traces, electrically connect connectors and components to each other. They run signals between these functions, allowing the board to operate in a specifically designed manner. The features range from simple to complex, but the PCB may be smaller than a thumbnail.
