Momentum II HiE Stencil Printer
The new Momentum II HiE is a single-rail stencil printer with servo motors, rather than stepper motors, driving the vision system’s X, Y, and Z axes. Faster than steppers, servos drive the vision gantry at higher speed and thus increase throughput and cut cycle time, making the Hi-E an efficient high-volume printer. New features enable improvement in productivity, yield, versatility, and ease of use.
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.
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.
The MPM patented Vision and Inspection system is a cost-effective, printer-based method to verify print and paste deposit results. The system is flexible enough to handle the complete rage of today’s most challenging components.
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 EdgeLoc system uses a side snugging technique that removes the need for top clamps which interfere with the PCB to stencil contact. The result is optimal gasketing and more volumetrically consistent edge-to-edge prints. Choose the robust EdgeLoc II with side only clamping or EdgeLoc+ which can change between edge and top clamping.
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.
New quick release squeegee blades make changing blades quick and easy with no tools required. It takes less than 30 seconds to change the blade. Momentum II offers an advanced print head featuring a high precision load cell with closed loop pressure control for precise and consistent squeegee force.
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.
MPM’s Adjustable Stencil Shelf provides the flexibility to handle all stencil sizes with a simple adjustment of the shelf. The robust design provides better stability on all stencil 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.
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.
Overview
The MPM Momentum II stencil printer is a proven, highly productive printer platform with industry leading accuracy and repeatability (certified by third party). Enhanced technologies provide further improvement around machine productivity, yield, ease of use, and flexibility.

New features enable improvement in productivity, yield, versatility, and ease of use.
The Momentum II stencil printers are 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
Machine vision inspection occupies a significant amount of time in each print cycle. Most of that involves the physical motion of system components. By speeding component motion, we shave away cycle time, increase efficiency, and accumulate savings.
Alignment repeatability of ±11 microns @ 6 sigma, Cpk ≥2 and wet Print accuracy of 20µm@6σ, Cpk ≥ 2, with 6σ capability designed in and independently verified. The MPM Momentum series printers are fast, precise, and highly reliable, with performance unmatched by any other printer in their class.
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.
Enhanced Technology
AccuCheck Print Capability Verification allows the printer to measure its own print capability. Users can verify the machine’s capability at any time or continuously on their own products. AccuCheck measures the actual print deposit position versus the target pad to determine a measured print offset. It is an inexpensive, reliable method of obtaining machine quality and process capability information to ensure repeatable results and optimum printing performance.

The EnclosedFlow print head offers significant process and cost advantages over printing with metal squeegee blades, particularly for fine-feature printing. Solder paste is held within an enclosed chamber, and is directly pressurized during the print stroke to provide uniform and complete aperture filling for the full range of aperture sizes and fill types.
The EnclosedFlow print head delivers superior volume/yield on fine pitch pads. Print fine pitch features such as 01005s and 0.3 mm pitch CSPs with up to 50% greater volume and 25% lower deviation that squeegee blades. The EnclosedFlow print head ensures optimal aperture filling for fine pitch devices and crisp uniform printing with less waste.
MPM’s patented printe rbased Vision and Inspection system is a cost-effective way to verify print and paste deposit results. It is flexible enough to handle the complete range of today’s most challenging components. This system measures the amount of paste covering the target pad and compares it with the required coverage. 2D inspection is integrated directly into the stencil printer to provide an immediate source of data.
MPM’s OpenApps is an open architecture source code which provides the capability of developing custom interfaces in support of Industry 4.0 initiatives and communication with Manufacturing Execution Systems (MES). ITW EAE is the first SMT company to offer open software architecture.
The Paste Height Monitor is designed to prevent defects caused y inadequate volumes of paste on the stencil. It combines advanced software and sensor technology to accurately monitor the paste bead for volume consistency. Upper and lower limit roll-height monitoring eliminates insufficient or excess paste volumes. It is a non-contact solution that can automatically add more paste to the stencil as it is needed.
Temperature monitoring ensures proper paste viscosity to avoid bridging and voiding. MPM patent- pending paste temperature monitor allows paste to be measured in the cartridge or on the stencil.
The PrinTrack feature adds traceability, data harvesting, and reporting to your printing process. With PrinTrack, you always have an easy access to a comprehensive history, detailing:
- How your product was printed
- When it was printed
- The process parameters used to print the board
- All pertinent information that can be used to track products or troubleshoot the process if needed.
A flexible web reporting interface can be user-configured to produce traceability reports.
