What it is

The DEK 248 is a flexible, semi-automatic, surface mount screen printer.^[1]

The DEK 248 can be configured to accept the DEKalign4 vision system.^[1]

How it works

The DEK 248 uses micro-controlled menu-driven operation with programmable machine parameters.^[1]

Up to 30 separate menu files of 12 characters each can be stored within the printer.^[1]

The speed of separation between the PCB and stencil is programmable for fine-pitch applications.^[1]

The printer uses castings and precision machine-tool bearings to ensure accuracy and repeatability in demanding fine-pitch applications.^[1]

Camera support arms and a single-point release button reduce set-up time.^[1]

A linear bearing system provides smooth, robust motion when aligning cameras to the PCB or mylar.^[1]

The system controller communicates via a back-lit LCD 4-line display operator panel.^[1]

The DEKalign4 vision system improves handling of HASL boards and can be extended with new vision enhancement packages.^[1]

The machine supports double squeegee print, print/flood, and flood/print operational modes.^[2]

Where it fits in the process flow

The board feed direction on the DEK 248 is left-to-right.^[2]

The machine operates as a stand-alone unit.^[2]

Applications

The DEK 248 is capable of printing 0.3 mm pitch QFP packages and 0402 chip packages using vision alignment.^[2]
