Having an accurate inventory is critical to any production process. This is especially true in a dynamic SMT line where frequent changes take place. To maintain the highest accuracy, components must be counted each time they are returned to stock.
Many pick-and-place systems will track and report component usage, including mis-picks. However, error still will exist such as losses when loading or unloading feeders and the more than occasional use of short pieces of tape for rework and R&D purposes.
X-ray based component counters substantially reduce counting time and can improve counting accuracy. The simplified operation also reduces handling risks.
