PCB Assembly & the role of QC Inspection

Employing Quick Turn PCB assembly services grant additional time for testing prior to full-scale production. Your chosen PCB manufacturing company will be able to deliver Quick Turn PCBs very quickly, thereby giving you time to test for issues and defects.

With a full turn key PCB manufacture, even very minor issues can lead to huge ones if they are replicated on a large scale. For example, if the layers of a PCB are not of uniform thickness, a number of problems can arise, potentially rendering an electronic device completely useless.

The process of testing printed circuit boards is an extremely important stage of production and it goes without saying that testing saves time and protects against costly mistakes in the long run.

Some common inspection processes that are conducted by PCB manufacturing companies include;

• AOI PCB inspection: This process of inspection uses an optical device to capture a picture of the assembled PCB to identify any faults.

• X-Ray Inspection: X-ray inspection is appropriate for more complex boards and has capabilities that other inspection methods do not provide. An X-Ray inspection allows you to view solder junctions, revealing bubbles that an optical device alone cannot see.

• AXI PCB inspection: As the density of PCBs increases, all of the solder connections are not always visible. As a result, the optical examination may be an ineffective tool for checking to solder. In such circumstances, an X-Ray system – AXI – can penetrate behind the chips to view the solder connections.

• Manual PCB inspection: As the name indicates, the manual method of the inspection involves an assembly review by the human eye.

Errors are often uncovered by testing. For example; if components fitted to the board are not appropriately chosen SMD components, the odds of the landing pattern being incorrect are significantly increased.

While it may be tempting to view the testing process as a resented expense, the reality is that the cost of failure may be significantly higher than the added cost of the inspection.
