Manufacturing Process of Printed Circuits Unlimited

Printed Circuits Unlimited is a company that specializes in manufacturing printed circuit boards (PCBs). The company has a streamlined manufacturing process that ensures quality and timely delivery of PCBs to clients.

The manufacturing process of Printed Circuits Unlimited involves the following steps:

  1. Designing: The first step in the manufacturing process is designing the PCBs using computer-aided design (CAD) software. The design is then sent to the fabrication department for further processing.

  2. Printing: The second step is printing the design onto a copper-clad board using a special printer. This process is called the “artwork transfer” process.

  3. Etching: The third step is etching the board to remove any unwanted copper. The board is then cleaned to remove any debris.

  4. Drilling: The fourth step is drilling holes into the board for components to be inserted.

  5. Plating: The fifth step is plating the board with a thin layer of copper to protect it from corrosion and to improve its conductivity.

  6. Solder Mask: The sixth step is applying a solder mask to protect the copper traces and prevent solder bridges from forming.

  7. Silk Screen: The seventh step is applying a silk screen to label the components on the board.

  8. Testing: The final step is testing the board for functionality and quality assurance. The board is tested using automated testing equipment to ensure that it meets the client’s specifications.

Printed Circuits Unlimited uses advanced equipment and techniques to ensure that the PCBs they manufacture meet the highest quality standards. The company also offers customized PCBs to meet the specific needs of their clients.

Quality Control in Printed Circuits Unlimited Manufacturing

Printed Circuits Unlimited (PCU) is committed to providing high-quality printed circuit boards (PCBs) to its customers. To ensure that every PCB meets the highest standards, PCU has implemented a rigorous quality control process throughout the manufacturing process.

Incoming Inspection

PCU’s quality control process begins with incoming inspection. All materials, including copper clad laminates, solder masks, and silkscreen inks, are inspected upon receipt to ensure they meet PCU’s strict quality standards. Any materials that do not meet these standards are rejected and returned to the supplier.

In-Process Inspection

During the manufacturing process, PCBs are inspected at every stage to ensure they meet PCU’s quality standards. This includes visual inspections, electrical testing, and automated optical inspection (AOI). Any defects that are detected are immediately corrected, and the PCB is retested to ensure it meets PCU’s standards.

Final Inspection

Before a PCB is shipped to the customer, it undergoes a final inspection to ensure it meets all of PCU’s quality standards. This includes a visual inspection, electrical testing, and AOI. Only PCBs that pass this final inspection are shipped to the customer.


PCU is committed to meeting industry standards and has obtained several certifications, including ISO 9001 and UL. These certifications demonstrate PCU’s commitment to quality and provide customers with the assurance that they are receiving high-quality PCBs.
