When you use PCBs in your projects, you have to be sure that they will perform well and make your clients felicitous. It is important to have a reliable way to test PCBs for flaws and make sure that they work as desired.

PCBs are becoming smaller and more intricate. These days, printed circuit boards might have thousands of soldered joints and numerous tiny components.

How an automatic optical inspection system works?

How can we define AOI? Automatic optical inspection system is a visual inspection of finished circuit boards with a machine scanner that uses light imaging. It assesses the quality of the craftsmanship to make sure the PCBs are suitable for use and purchase.

An Automatic optical inspection PCB generally contains several light sources and many cameras, and may also include video cameras.

The role of an Automatic optical inspection PCB

Automatic optical inspection equipment plays a crucial role in PCB production. It ensures every board can deliver top performance necessary in intricate electrical ...
... applications.

When AOI unveils a flaw in the PCB, it flags the board to go back for fixing it. The procedure may happen in different ways. The findings of the AOI may fail precise amenity needs, a necessity that all the lines on a board should be over a specific size, for example.

Component Flaws

Component flaws are defects in the small functional parts attached to a board. Here is a general component flaws on PCBs:

• Misplaced or misaligned component

Misplacement or misalignment may happen when the production process puts components improperly or when components shift after the placement. Component shifting is common during reflow as it is simple for parts to move above molten solder. The surface tension of the solder entails components might glide easily. In case of a misplaced or misaligned component, the PCB might still work, but in a sluggish way.
