Exhibitors such as Nordson Asymtek and Vermes Microsdispensing will showcase new types of dispensing machines and innovative advance developments of non-contact jetting valves. As Gerd Schulze, Sales Manager at Nordson Asymtek, explains, automated process controls are becoming increasingly important in this area: "Keeping the process stable within very close limits is increasingly important for our customers. For reproducible processes and 100% tracking, monitoring processing parameters and automatically adjusting them when necessary is an absolute must." During LED manufacturing, it is essential to ensure that the colour temperature of the LED is within the specified range. This calls for extremely precise and reproducible dispensing. Too much or too little material can influence colour temperature considerably and could result in the LED only qualifying as "second rate". The materials being dispensed are generally two-component mixes, some of which are very difficult to process. For this reason, automatic process controllers on dispensing machines are required to ensure consistent results.
