The main screen provides a drop down menu where the part to be inspected can quickly be selected. An operator then loads the chosen part into a customized fixture and presses the inspect button. Two DVT® cameras concurrently inspect multiple solder joins on both of two switches. Camera images and inspection results are displayed on the main screen along with daily statistical totals and this data is recorded to a database. The system can create a report displaying data for each part type over a selected time interval.
