DEK TQ

The DEK TQ marks the next generation of stencil printers. Newly designed from the ground up, this new generation of DEK printers is faster, more precise, more powerful with extremely low maintenance and high production uptime, and easy to integrate into your assembly line. New linear drives, off-belt printing and innovative clamping system ensure a new level of accuracy and deliver a stable printing process – even for the latest 0201 metric components. In the new DEK TQ, precision and speed are inseparable to meet your future requirements. A new 3-stage transport and the unique ASM NuMotion controller with fiberoptic based communication reduce the cycle time to 5 seconds and deliver high-precision performance in the smallest possible footprint.

DEK Smart Pin Placement (SPP)

SPP is a tooling system that enables the printer to place support pins on to the tooling table automatically and precisely in a user configurable layout created to match the board being printed. The system provides for 30 tooling pins of two different sizes, a quantity of 15 x 4mm support pins and 15 x 12mm pins are provided with the DEK TQ option. This allows for extra flexibility in positioning tooling pins as generally it can be assumed that the more board support placed, the better the substrate will be supported during printing. Programming of tooling pin positions can be achieved in various ways depending on the user’s factory environment and their integration into ASM line control software (Siplace Pro).
