AL Series


EMMA with vertical type full automation. With newly developed auto loader/unloader on the side 24 hours unattended testing is now possible. Once the boards are stacked on the loader, suction pads automatically conveys the boards to the test area. Once the test is complete, boards are speedily transferred to unloader, separate to PASS and FAIL boards.

Medium and High Volume Production Model with Auto Loader

Boards Transfer Method: Conveyer Method
Max. Stackable Boards
Autoloader: 200pcs
(when board thickness is 1.6mm. Max. stackable weight: 80kg)
Unloader: PASS Boards 200 pcs, FAIL Boards 60 pcs (when board thickness is 1.6mm. Max. stackable weight: 80kg)
Inclusion of stamp unit is available (Optional).
Supports multi-image boards

Conveyer Method

* Multiple boards with different size may be stacked at same time.
* Stackert may be separated to devide into PASS and FAIL boards.
* Conventional E4M, E4H and E4S cannot be connected to full automation
