Diabetes affects many millions of people worldwide. New technology for real-time glucose measurement replaces the usual unpleasant pricking of a finger: a sensor located in the subcutaneous tissue of the diabetes patient measures the glucose values and transmits them to a receiver. Production of such medical wearables calls for high-precision dispensing systems for applying very small amounts of UV adhesives to medical PCBs and for integrated system concepts to achieve this. A perfect task for Scheugenpflug.

The present work concerns on the use of sensors to monitor the structural health of wind turbine . Conventionally the inspection was made using non-contact sensing during the turbine’s inoperable period hence loss occurred. A real -time monitoring system via embedded wireless sensor is preferred but the sensor could only be implanted using non-contact printing method due to most turbine blade s’ curved surface. Conductive ink associate d with non-contact printing method via fluid dispensing system are proposed since conductive inks are proven stretchable and fluid dispensing system enables printing on various substrates and works well with any materials...

To meet the steady increase in technical requirements for electronic components, potting media properties must be extremely precise. Rheology, viscosity, filler content and curing behavior are only a few of the factors that play a role in their practical use. However, the growing complexity of materials often negatively impacts the ability to process or dispense them. In this case, material preparation and feeding systems specially designed for this purpose are required. These systems optimally prepare the material for the actual application and ensure homogeneous feeding to the dispensing system.

Robotics for automated fluid dispensing have the ability to apply a variety of materials including epoxy, silicone, and acrylic coatings. These materials are extensively used in today’s high-speed fluid dispensers for the electronics industry. Whether a dispenser is applying epoxy or another material, the central concept for applying any form of material remains the same. Specific points of an item being dispensed onto are programmed into the dispensing system. The automated fluid dispensers software interprets the programmed information and keeps the travel path in memory. A robotic arm moves fluid dispensing nozzles along this travel path and applies epoxy onto the surface of the item with precise accuracy. Machine speed can be adjusted to emit varying amounts of epoxy. The overall application process is auto-regulating and will not be disrupted.

Quality monitoring for verifiable, high-precision application of adhesives and sealants now begins with detecting the position of the component. Dispensing systems are in continuous use and have to work with 100 percent accuracy. And this level of accuracy must be verifiable. Demands on electronic components continue to escalate as these components also need to operate continuously and flawlessly, especially in the automotive and medical sectors. At the same time, there is increasing pressure to automate as companies are looking to achieve the shortest possible cycle times and maximum output.

Today's automated dispensing for electronics manufacturing is a complex and precise process in order to meet the challenges posed by ever more demanding assembly and component technology requirements. Dedicated dispenser technology is key to success in meeting challenging applications in a production environment with precision and repeatability. The major components that comprise a dispenser will be described, with a view toward understanding the importance of each; the result will illustrate how these sub-systems combine to create high-volume dispensing platforms. Real world examples with data substantiating the speed and accuracy obtained for some of the most common advanced dispensing applications in the market will be demonstrated such as high speed surface mount adhesive, wafer level Underfill and shield edge interconnects.

Critical to maintaining quality control in high-throughput screening is the need for constant monitoring of liquid-dispensing fidelity. Traditional methods involve operator intervention with gravimetric analysis to monitor the gross accuracy of full plate dispenses, visual verification of contents, or dedicated weigh stations on screening platforms that introduce potential bottlenecks and increase the plate-processing cycle time. We present a unique solution using open-source hardware, software, and 3D printing to automate dispenser accuracy determination by providing real-time dispense weight measurements via a network-connected precision balance. This system uses an Arduino microcontroller to connect a precision balance to a local network. By integrating the precision balance as an Internet of Things (IoT) device, it gains the ability to provide real-time gravimetric summaries of dispensing, generate timely alerts when problems are detected, and capture historical dispensing data for future analysis. All collected data can then be accessed via a web interface for reviewing alerts and dispensing information in real time or remotely for timely intervention of dispense errors. The development of this system also leveraged 3D printing to rapidly prototype sensor brackets, mounting solutions, and component enclosures.

Simply put, the proper system design and use of vacuum in the potting process can make the difference between a mediocre part and a perfect part. Air entrapment is inevitable whether you utilize syringes, cartridges, pails, or drums of material in the process.

To compensate for the insufficiency and instability of solder paste dispensing and printing that are used in the SMT production process, a noncontact solder paste jetting system driven by a piezoelectric stack based on the principle of the nozzle-needle-system is introduced in this paper, in which a miniscule gap exists between the nozzle and needle during the jetting process.
