When it comes to epoxy dispensing your vendor system must offer the ultimate flexible platform for demanding environments. The epoxy dispenser should meet the highest standards of reliability and dependability and ideally be recognized by the market as the industry standard. The epoxy dispenser’s platform must be configurable with a history of an installed base in advanced packaging across a wide range of market segments, such as aerospace & defense, optoelectronics, life and health sciences, automotive, lighting, and communications.
The most appropriate epoxy dispenser system should deliver key commercial results for your business:
- Increase capacity at lower cost – Separating the dispensing process step from the placement operation translates into lower costs by leveraging both machine types for what they do best.
- Less Labor Cost – Automatic needle cleaning, automatic calibration routines mean less operator intervention and higher productivity with your epoxy dispenser.
- Lower Cost of Ownership – Commonality with placement machines means lower spare parts cost, lower parts inventory, lower training costs.
- Higher Yields – High precision, automated process control functions, proven pump technology all come together to ensure maximum yields, which in turn translates into a lower cost per part.
- Flexibility – Handle whatever comes your way with the ability to use the right pump for the right application with your epoxy dispenser.
To deliver these results, your epoxy dispenser system will have the following advanced functionality:
Epoxy Dispenser Key Functionality
- Dispense Pump Technologies – In addition to rotary style positive displacement pumps, the epoxy dispenser should have the option to select jetting, stamping and time/pressure pumps including fully digital enhanced time/pressure with an integrated Mushashi Engineering controller.
- Confocal Height Sensor – A confocal height sensor is used to precisely determine dispense heights. The advantage of the confocal sensor is that it allows vertical measurements in deep cavities and in close proximity to walls and other obstructions.
- Real Time Video Provides Process Monitoring for Dispense and Assembly – Real time video is essential to monitor the dispense and assembly process on an Epoxy Dispenser system. This is an excellent tool for process development providing the engineer with a unique view of the assembly process. Improvements in available LED lighting, camera form factors, and resolution as well as monitors means the quality of the image displayed is excellent. For advanced manufacturing and particularly those configured to view their “unmanned factory” remotely enjoy the benefits.
- Volume Scanning and Display Software – The epoxy dispenser should have the ability to scan an area with the confocal height sensor. The 3D data is then processed to get a volume measurement. The system reports if the result is outside the control limits. An image of the surface topography based on the scanned data is displayed during production.
- Image Storage for Verification and Traceability – This option allows the operator to select and store images for each dispense and placement in an epoxy dispenser program.
In summary, the epoxy dispenser system you choose must have the capabilities to solve these problems:
- Handling of small and fragile compound semiconductors (CS) components requires attention to placement forces and orientation.
- Components must frequently be placed in cavities, translating into a need to image and process components in multiple planes.
- Components with air bridges and other “no touch zones” require non-conventional pickup.
- Components are typically not symmetrical and orientation must regularly be determined using top-side features prior to placement.
- A robust epoxy dispenser platform is required to allow for variations in materials and process.
Specifically, we believe our MRSI-175Ag epoxy dispenser system has the capabilities to match these requirements.
MRSI’s Epoxy Dispenser Solution – MRSI-175Ag
The MRSI-175Ag Epoxy Dispenser is a servo-controlled X, Y, and Z platform. The epoxy dispenser has a Rotary Style Positive Displacement Pump with a new higher resolution motor. This means the MRSI-175Ag has even better performance. The MRSI-175Ag offers a wide variety of application specific pump technologies including a rotary positive displacement auger pump for precise, continuous dispense of small dots, lines, arcs and areas. The system allows for quick change-over from dispensing conductive epoxy to dam and fill and underfill materials. The epoxy dispenser’s advanced vision system combined with programmable tri-color lighting assures accurate fiducial registration for precise placement of dispensed patterns. Laser height sensing maintains critical dispense heights. The epoxy dispenser features two dispense heads. These heads can be used for two dispense pumps, one dispense pump and one stamping head. Automatic tip calibration, tip cleaning, and purge stations make setup quick and easy. The MRSI-175Ag epoxy dispenser is frequently selected based upon the ease of programming. The epoxy dispenser uses the same icon based interface running on a Windows™ as the MRSI Systems’ family of die bonders, thus reducing training time and improving productivity. The MRSI-175Ag may be configured for manual part loading, magazine to magazine part handling, or for in-line production.
In summary, it is important to demand a comprehensive set of specifications when choosing an Epoxy Dispenser System, to ensure the business maximizes the return on its investment. We would be delighted to demonstrate how we meet that specification. Contact MRSI Systems to see how we can help solve your epoxy dispenser challenges – sales@mrsisystems.com.
