Soldering optical inspection

Automated optical inspection (AOI) for quality control becomes the main issue in all manufacturing processes to ensure effective functioning of the products and achieve the zero defect goal. However, most of the quality controls use a 2D camera and are limited to pattern or colors recognition, which is not sufficient for many applications and especially for solder joint quality.

As a specialist in selective soldering technologies, we developed a complete and very performant 3D inspection solution for quality controls. We combine a 3D sensor with our mta well-proven platforms and MotionEditor software, using a cartesian 3-axis robot. This enlarges the possibilities to almost all kind of quality controls.

The main features of the soldering optical inspection system include:

  • Accurate and fast 3D image & 2D monochrome image acquisition at the same time
  • Wide range of 3D and 2D tools for all type of inspection
  • Pattern projection from 2 different directions providing minimal shadows influence
  • Control sequence and programming supply by our expert with dedicated HMI
  • Easy handling with a simple sequence of joint inspection related to vision recipes

5 benefits compared to traditional cameras

  1. Reproduction of the solder joint in 3D.
  2. Precise measure of the part.
  3. Cross section and analysis of the profile.
  4. Only one sensor instead of two or more cameras to analyze the solder’s meniscus.
  5. Standard software for each application.
