  • Dispense for standard cartridges or choose the new patent-pending jar dispenser.  Paste is released in precise, measured amounts across the stencil in a clean, uniform bead.  Deposition volumes, frequency and placement are user programmable.

  • The highly efficient triple track rail system features an input buffer, a central processing section, and an output buffer.  A new board can be indexed into the machine and positioned next to the center-nest, readying to print, while the two others are being loaded and off loaded.  Cycle time is shortened because boards don’t have to move single file through the printer.

  • Automatic Pin Placement is MPM’s patented tooling solution that uses the vision gantry to precisely place and remove tooling pins.  The carousel holds 48 pins to match and support the largest board size.  A standard grid for single sided boards or an exact pin placement for double sided boards can be developed. Pin location can now be verified with bottom side image whether placing pins automatically or manually.

  • MPM’s new paste management system provides innovative tools to improve yield and enable Industry 4.0 traceability. The system includes an industry-first paste temperature monitor, measured for proper paste viscosity and a roll height monitor that now measures both upper and lower limits. All data can be recorded for board traceability. It’s a non-contact solution that can automatically add more paste.

  • The MPM EnclosedFlow Print Head delivers uniform aperture filling and superb printing performance especially for fine pitch devices. It also provides substantial saving on solder paste over squeegee blade printing - in excess of 50% over blades for dramatically fast ROI.

  • Camalot Inside consists of two dispense pumps integrated into one printing machine.  Camalot Inside provides ultimate flexibility, allowing the dispensing of two different materials, or the same material (doubling dispense throughput speed) with two needle sizes to easily administer multiple dot sizes.

  • RapidClean is a high-speed stencil solvent cleaning innovation that slashes cycle time and improves stencil cleaning performance, especially for fine-pitch.  RapidClean reduces 3 wipe strokes to 2 and cuts cycle time by 5 – 6 seconds per print cycle over the standard wiper; and because fewer cleaning cycles are required, RapidClean can save up to $10K USD per annum in paper savings per printer.

  • Easy to learn and use for the average operator, MPM’s Benchmark software is powerful yet intuitive, and facilitates rapid setup, assists with operational tasks, and makes changeover quick and easy.  The software has been upgraded to Windows 10 and new production tools and new Quickstart programming to make it even easier to use.

Overview

The MPM Momentum II stencil printer is a proven, highly productive printer platform with a new set of enhanced technologies for further improvement around machine productivity, yield, ease of use, and flexibility.

The Momentum II Elite stencil printer is the top-performer of the Momentum series, boasting the highest throughput and shortest cycle times of all. Its vision system is driven by servos for speed, and it’s configured with a highly-efficient triple track rail system that saves cycle time by buffering PCBs inside the machine. A new board is indexed into the machine and positioned next to the center nest, readying to print, while other boards are being loaded and offloaded.

The Momentum II is designed for high throughput and accuracy. MPM’s rigid frame is welded for low vibrations and major assemblies are driven by precision ball screws.  This allows for higher repeatability and greater reliability over time. 

Momentum II has an advanced print head featuring a high precision load cell with closed loop pressure control for precise and consistent squeegee force. Tighter performance tolerances mean consistent repeatability with higher yield.

Benefits and Features

Higher Throughput, Shorter Cycle Times

The Momentum Elite is intended for high-volume applications. The Momentum Elite, with its triple track conveyor rails and servo drive motors, provides the greatest throughput capability of the Momentum series, making it the ideal printer for high volume, high mix assembly lines.

Proven Momentum Series Accuracy and Performance
