Automatic optical inspection of printed circuit boards

An automatic optical inspection system (AOI) has been developed to check the placement of printed circuit boards, which detects a wide range of characteristics.

• Tombstoning
• Tin splash on component
• Components not present, twisted, etc.
• Check for bent pins (pin spacing min. 0.4mm)
• Color coding on components

Key facts of printed circuit board control:

• max. width of 460 mm
• smallest component 02-01 -> 0.6×0.3mm
• Interface between individual devices: SMEMA
• Stand-alone or inline possible

The 3D model creation is performed by data acquisition of a golden sample, which must be manually controlled by an employee beforehand. If the golden sample is considered good, a 3D point cloud is recorded and a 3D CAD model is created. Also, a 2D line scan camera is used to capture a color image of the printed circuit board. Based on this color image, the inspection criteria are selected in the software.
