AOI inspection – Automatic Optical Inspection

Automatic optical inspection (AOI) is a crucial step following electronics manufacturing, during which all assembled circuit boards undergo precise testing. The main objective of AOI testing is to detect errors that may occur during the manufacturing process at an early stage. This significantly increases the quality and reliability of electronic assemblies.

In combination with a customer-specific inspection concept, AOI is an excellent complement to electrical testing methods. This saves time and costs and ensures higher product quality.

3D AOI

At Gugler Elektronik AG, we rely on state-of-the-art 3D AOI inspection equipment. This form of quality control in electronics manufacturing is based on three-dimensional images of the printed circuit boards in order to reliably detect defects. In contrast to 2D AOI, which only captures two-dimensional images (length and width), 3D AOI also enables the precise detection of height differences (Z-axis) of components and solder joints. 3D AOI can thus detect defects that are not visible with 2D AOI, e.g. faulty solder joints under components or components that are not seated correctly on the board.

In addition, we rely on the high level of expertise of our employees, who receive continuous training in the latest technologies to ensure that they are always up to date.
