Electronic Assembly Printers

Edison Stencil Printer

  • The next generation MPM Edison stencil printer is designed to meet the demand for increasing throughput, yield and performance requirements from the automotive, smart device and semiconductor markets. Edison is optimized for ultra-fine pitch (0201M) printing with a transfer efficiency up to 75% for small apertures.

  • 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.  

  • Board Staging is a new Edison feature that provides the ability to have three boards in the machine simultaneously. It pre-loads the next board on the input conveyor during the print process resulting in reduced transfer times and improved cycle time.

  • The walk-in design of the Edison printer allows easy access to tooling during changeover. All serviceable controls are also located in the front for easy access.

  • Edison’s ultras-fast, high efficiency wiping system features a super-size 65m paper roll with patented constant tension control, makes 10,000 prints possible before a roll change is needed, reducing downtime and operator interface. The wiping zone is isolated from the printing zone to avoid cross contamination.

  • Edison is available in a Back to Back (BTB) configuration. This is a flexible dual lane solution without adding line length; identical single-lane printers are easily re-deployed to other lines when needed. Use in BTB configuration, or singly as a stand-alone.

  • 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.

  • Edison’s advanced print head features a single high precision load cell with closed-loop pressure control and motor drive system enable precise and consistent squeegee force control across print stroke in both directions, which helps improve yields especially for challenging thin substrate printing in the semiconductor industry.

  • 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.

  • Quick release squeegee blades make changing blades quick and easy with no tools required.  It takes less than 30 seconds to change the blade.

  • Edison features a high-speed vision alignment system with an ultra-thin camera. The overall gantry thickness is only 39 mm featuring an ‘on the fly’ ‘POE’ (Power Over Ethernet) camera. A single CCD split field provides precision simultaneous up-down image acquisition with a field of view 9.0 x 6.0 mm.

Overview

The MPM Edison™ stencil printer is ideally suited for the growing Automotive and Smart Device manufacturing markets.  The Edison printer is the industries’ most accurate printer with +/- 15μ @ 6σ wet print repeatability. Total throughput is lightning fast due in part to the highly-efficient, parallel processing of the stencil shuttle system, stencil wiping, paste dispensing and vision alignment system.

Benefits and Features

Faster Throughput for a Better Process

Edison’s new parallel processing system is extremely fast resulting in a very short cycle time. This helps increase throughput by shortening total time per PCB printed. This leaves more time for key overhead functions that have the biggest impact on print quality:

  • Print at slower speeds to decrease variability
  • Utilize slow stencil separation for optimal print definition
  • Double stroke after wipe
  • More frequent wiping resulting in higher yields
  • Time leftover to optimize settings for maximum possible yields
Incomparable Wet Print Accuracy

Best-in-class printing with a 25% improvement in wet print accuracy over current printers: Built-in +/- 8 micron alignment, and +/- 15 micron wet print repeatability (≥2 Cpk @ 6σ) proven through 3rd party Print Capability Analysis (PCA) testing.

Back To Back (BTB) Configurable

BTB is a flexible dual lane solution without adding line length; identical single-lane printers are easily re-deployed to other lines when needed. Use in BTB configuration, or singly as a stand-alone.

Intueri Graphical User Interface

MPM Intueri is a simple, intuitive operator interface with a flexible, wide array of configuration variables. It is combined with OpenApps for maximum capability and connectivity and provides a portal to Industry 4.0 concepts.

Enhanced Technology

Advanced Print Head

Single-axis, closed-loop pressure control for dual squeegee eliminates front-to-back variation.  A single high-precision load cell provides squeegee force, and a unique algorithm calibrates out non-linearity, maintainng the set pressure across the entire board surface.  

Board Staging

Ability to have three boards in the machine simultaneously, reduced distance on input conveyor by pre-loading the board during the print process results in reduced transfer times and improved cycle time.

EdgeLoc Board Clamping

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. With EdgeLoc II, robust flippers engage to secure the board across the top edge ensuring board flatness then move out of the way once the board is firmly gripped from the side. EdgeLoc+ board clamping can change between edge and top clamping simply through software.

High Speed Vision Alignment with Ultra-slim Camera

Edison features a high-speed vision alignment system with an ultra-thin camera. The overall gantry thickness is only 39 mm featuring an ‘on the fly’ ‘POE’ (Power Over Ethernet) camera. A single CCD split field provides precision simultaneous up-down image acquisition with a field of view 9.0 x 6.0 mm.

OpenApps Architecture

OpenApps is an MPM open architecture source code that allows customers and third parties to develop custom interfaces in support of Industry 4.0 initiatives and Manufacturing Execution Systems (MES).

Paste Height Monitor

The Paste Height Monitor is designed to prevent defects caused by 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.

SPI Print Optimizer

The SPI print optimizer communicates with the external Solder Paste Inspection (SPI) system to continuously monitor and auto-correct X, Y, and Theta registration ‘on the fly’ to stay on target and prevent print defects.

Ultra-fast, High Efficiency Wiping System

A super-size 65m paper roll allows 10,000 prints per change. Patented paper tension control provides more effective wiping and a separate wiping and printing zone prevents cross contamination.
