PCB Incoming Inspection
Printed circuit board (PCB) designs are getting increasingly demanding and complicated due to new technology. Innovations in PCB technology continues to break new grounds and require more advanced footprints. This complexity also means that components are more expensive and they become difficult to produce. It is essential that the PCB incoming inspection process takes more priority and relevance in the manufacturing process.
PCB incoming inspection helps to ensure that the quality of the final product of the PCB production line is impeccable. It is, therefore, essential that every part and component involved in PCB designs undergo an incoming material inspection before they are part of any final assembly.
A rigorous PCB incoming inspection process ensures that components do not ship with problems. It ensures that the pressure from the marketplace does not lead to high error rates from the manufacturing process. The inspection also reduces failure rates in electronics down the line. A PCB factory with a poor PCB incoming quality control will lose most of its clients due to reliability and quality assurance issues.
This process helps to identify parts that may be defective before they become part of the production flow or the inventory. All parts and materials must undergo rigorous inspection according to a strict PCB incoming inspection standard:
PCBs are of many different types and quality classes. This means that the complexity of the testing and inspection methods may vary. During PCB fabrication, it is essential to ensure that there is a strict inspection to ensure that the quality of PCBs is according to the design requirements of the client. The incoming inspection process depends on the standards of the manufacturer, industrial standards, and technological demands of the PCB design.
PCB incoming inspection includes:
- Visual inspection: These checks involve making sure that the board thickness, surface roughness, and dimensions are accurate. You can use a ruler, precise calipers, or a magnifying glass for the inspection. This also includes checking the quality of the plating flux, positioning of components, and the electrical connectors.
- General electrical inspection: This involves two types of tests. A connecting performance test ensures that the connectivity of conductive patterns is in line with expectations. An insulating performance test also checks the insulating resistors on the PCB planes are functioning correctly and pass all quality assurance checks.
- Electrostatic Discharge (ESD): Many components are sensitive to electrostatic discharge and an ESD test ensures that production follows all safe handling procedures. Elements that are part of highly sensitive electronics like cameras, digital scales, and measuring devices need to pass an ESD check to identify defects.
Incoming inspection procedure manufacturing is a function of quality assurance personnel and they ensure that incoming materials are appropriate. This process ensures that orders are accurate, reduce production costs, and it also helps to increase production quality.
Here at MOKO Technology, no component or part leaves the production floor without passing through a strict incoming inspection quality control process. This is why we are one of the leading PCB manufacturers and well respected in the world. In addition, our record of excellent customer service and reliability speaks for itself. And we remain committed to providing the best service in electronics manufacturing and satisfaction for our clients.
