INSPECTION OF LARGE SOLDERED JOINTS (LASOL)

• Abstract:

  The LASOL project comprises the development, evaluation and appraisal of a novel automated inspection system specifically designed for large area solder joints (LSJ). The LASOL project started in September 1998 and is co-funded by the Commission of the European Communities, DG XII, under its Brite/EuRam Program with the Project No. BE-4689. Current inspection systems based on grayscale imaging are usually optimized for very small joints (e.g. surface mount). These systems can check for the existence of a joint but provide inadequate information on its condition or quality. The LASOL system utilizes a non-destructive method based on the Coded Light Approach to optically inspect the joint surface in three dimensions. With this method the LASOL team intends to achieve: establishment of generic relations between geometric structures and quality functions (e.g. fluid and gas tightness or mechanical strength); definition of generic rules for process control using geometric measurement data; set-up and validation of an industrial pre-competitive prototype for automated inspection of LSJ’s. Actual results of topography registration, classification and rules of quality assurance of LSJ’s are presented.
