Grasping The Essential Guide to PCB Manufacturing Processes
Printed circuit board (PCB) manufacturing is a complex process that involves several key stages. Firstly, the design of the PCB is meticulously created using specialized software. This design determines the position of components and the routing on the board. Once the design is finalized, it is sent to a fabrication facility where the actual manufacture of the PCB begins.
- The first stage of PCB fabrication involves creating a copper-clad substrate from which the circuit will be etched. This substrate is typically made of fiberglass or epoxy and is coated with copper on both sides.
- Subsequently, the design data is used to create a photoresist mask, which protects certain areas of the copper during the etching process. The mask is then applied to the substrate using a process called photolithography.
- After the photoresist has been cured, the substrate is immersed in a solution that removes the exposed copper, leaving behind the desired circuit pattern.
Punching holes for components is another important step in PCB fabrication. The position of these holes is determined by the component placement in the original design. After drilling, the substrate undergoes a series of cleaning to remove any residual photoresist and contaminants.
