Adjust-a-Vac vacuum tweezer is for handling very thin/delicate substrates, wafers, MEMS devices and other fragile components. Can adjust vacuum level from 1-10" of mercury. Integrated 10-segment bar graph display shows vacuum level present during operation. Bar graph shows minimum vacuum pressure until part is grasped, then displays vacuum level presented to the part being handled. Vacuum port integrates a user-replaceable inlet filter.

THT-Line AOI for double-sided inspection of plated through-hole assemblies now comes with tape transport in addition to roller conveyor for work piece carriers. Inspects selective solder joints on assemblies transported without work piece carrier. Can be used both for actual manufacturing process in the upper area of the system as well as return transport in lower area of the machine. Also has laser measuring system for coplanarity control (e.g., for connectors) or for height measurements on various components. Up to two different and independently operating AOI modules can be integrated into a single system chassis.
