Performance leap in dispensing speed and for the smallest quantities - Scheugenpflug presents two trailblazing dispensing solutions for the electronics markets at productronica 2021
Scheugenpflug GmbH is meeting the industry's demands for increasingly short cycle times with the highest dispensing quality and the trend towards component miniaturisation with two new innovations: The DosPL DPL2001 piston dispenser for dispensing very small quantities, and the DosP DP2001 piston dispenser for up to ten times higher dispensing speeds even with highly viscous materials. Both solutions support electronics production in the automotive, industrial, medical and consumer sectors with accelerated processes and an increase in productivity.
Neustadt/Donau, 15th November 2021: At productronia 2021, Scheugenpflug GmbH, the world's leading manufacturer of high-quality bonding, dispensing and potting technology, will present two solutions for the booming electronics markets that set new benchmarks. That's because dispensing systems are key technologies in an environment of increasing automation and demand for high product output. Florian Weixelbaum, Product Manager at Scheugenpflug, is convinced by the result of the development work: "These two product innovations offer maximum productivity, flexibility and functionality to cope with increasing material viscosities, decreasing cycle times and reduced dispensing quantities."
High performance for series production
Material usually has to be dispensed as quickly as possible when using materials of very high viscosity such as thermal interface materials (TIM), whether for control units or battery systems. This is a task that the DosP DP2001 high-performance dispenser performs up to ten times faster than comparable solutions on the market. It dispenses 1C materials from 0.06 ml to 20 ml and 2C materials from 0.1 to 40 ml. The high dispensing speed for highly automated production lines enables a new reliable valve system with extremely short switching times. It works without a membrane and is particularly pressure stable.
Powerful servo drives ensure optimised power transfer and higher dispensing speed. To achieve the high dispensing speeds even with highly viscous thermally conductive heat transfer adhesives, the DosP DP2001 comes with a newly developed Premium mixing tube. These static mixing tubes with geometry developed in-house withstand the highest dispensing pressures without plastic deformation.
Maximum flexibility from even the smallest volumes
The trend towards the miniaturisation of electronic components is leading to increasingly small dispensing quantities and potting volumes. The new DosPL DPL2001 low-volume dispenser dispenses dots - smaller than pin heads - quickly, reliably and with maximum repeat precision. The dispensing quantity includes 1C materials from 0.003 ml to 2 ml and 2C materials from 0.006 to 4 ml. The high dispensing accuracy with fast cycle times is made possible by a new displacement-free valve system, which is also suitable for the use of abrasive materials due to its robustness.
The new technology is particularly advantageous in combination with the proven piston dispensing principle. This means that not only the smallest points and lines can be dispensed. The system also offers the greatest possible flexibility in terms of dispensing rates and volumes. As with the DosP DP2001 high-performance dispenser, powerful servo drives ensure the high dispensing speeds. In addition, new process possibilities arise such as adaptation of the mixing ratios to product-specific properties. This ensures greater flexibility and thus an extended range of applications.
Both Scheugenpflug dispensing solutions feature reliable process monitoring and access to relevant process parameters. The new sensor technology and software continuously monitors the dispensing pressure by component. Improved start/stop behaviour as well as more precise contours are decisive advantages, especially in the smallest quantity range, and are made possible by the new parameter selection of the material-specific dispensing pressure in the dispensing program.
The dispensing units can be used in the multi-function DispensingCell DC803 for atmospheric applications. Alternatively, it can also be used as an integration solution in conjunction with the process module.
