Operation
The AutoScan 4000 Stacker employs a single or dual Pick & Place Carriage each with dual Pick-up Heads, allowing the transfer of up to four components at once. This greatly increases the productivity of the system making it capable of transferring components at a rate of 5000 units per hour. The AutoScan 4000 Stacker is equipped with input and output JEDEC Tray stackers capable of handling 20 trays each. Standard systems have two stacker sets (one set is made up of an input and an output stacker), but additional sets may be added upon request.

To perform the lead inspections, the AutoScan 4000 Stacker employs an UltraVim or UltraVim Plus Inspection Module manufactured by Scanner Technologies Corporation. Scanner Technologies offers two types of Inspection Modules. The UltraVim is capable of inspecting Gull Wing and J-lead devices with 3D technology. The UltraVim Plus Inspection Module is capable of 3D Ball Grid Array Inspection as well as the Gull Wing and J-lead capability of the standard Ultra Vim. Both models operate at high speed and precision without any customer calibration at any time.

There are three modes of operation available to an operator. Mode One will inspect devices and sort them placing good devices in a separate tray and returning reject devices into the supply tray. Mode Two inspects devices returns all parts back to the supply tray then posts a "map" detailing the results in a graphic display. The Third Mode is simply tray to tray transfer without inspection.
