Printing without limits

The best of both worlds

To meet the needs of customers with mixed production strategies and growing batch sizes, Mycronic has added a screen printing solution to its portfolio of MYPro equipment for SMT production. Together with the new high-speed MYPro A40 pick-and-place and the full range of MYPro assembly solutions, the MYPro S series stencil printer contributes to the fastest full-line solution ever available to Mycronic customers. 

When it comes to printing solder paste, nothing beats Mycronic’s Jet Printer in terms of flexibility. But when deadlines are tight and batches are larger, Mycronic’s new stencil printers can be added to a Jet Printer for the ultimate in speed and reliability. Working in tandem, the stencil printer brings its unbeatable cycle time for average paste deposits, while the Jet Printer handles all deposits with non-average thickness or shape with unparalleled speed and accuracy. Need to switch production? Simply replace the stencil and select the next jetting program.

Introducing the MYPro S series

Launched at Productronica 2023, the MYPro S series is a robust, highly accurate and user-friendly stencil printer. True to the MYPro production philosophy, it has been designed to enable the fastest possible changeovers and features all the functionalities expected from a modern screen printer.

In the MYPro S series, an advanced vision system ensures complete alignment between the stencil and PCB, while a ­climate control feature maintains the physical qualities of the solder paste to ensure consistent print quality. During the printing phase, squeegee pressure is permanently monitored, and any deviation is displayed on the control screen for immediate correction. Each printed board can be 2D inspected to ensure that no deposits are missing, and after each stencil cleaning phase, the stencil itself is 2D inspected to make sure it is valid for production. Traceability, an essential ­feature in the manufacturing of high-reliability electronics, is assured through automated tracing of each stencil, solder reference number and operator ID.

The printer has a robust frame with a marble support beam achieving high rigidity and long-term repeat accuracy of ± 8µm. Squeegee movement uses a ball-screw with direct servo connection which adds to long-term consistent printing. The transport rail is motorized with dual guide rails and dual ball-screw, ensuring long-term stability.

Closed-loop quality with PI series SPI

For even greater control, the MYPro S series screen printer could be interfaced with all Mycronic PI series 3D SPI models. Thanks to an optional closed loop software, the PI series 3D SPI can automatically adjust the position of the stencil in X and Y, as well as its angle of rotation. And if print quality deteriorates, the 3D SPI can be set to automatically trigger a cleaning cycle.
