DEK 265 Horizon Automatic In-Line Screen Printers
(we have two fully automated machines and two semi-automated machines)
This machine is a fully automatic in-line stencil printing system. It is preceded in the assembly line by an automatic magazine feed board loader/feeder. Once a board is loaded into the magazine feeder, the total SMT operation is hands-off until the board is completely assembled and reflow-soldered. This machine is an integral part of that in-line system. Like the pick-and-place machines, this machine is vision driven.
