The Nordson EFD PICO Toμch controller

The battery is the key to the performance of an electric vehicle. Its lifetime and quality determine the driving range and overall safety. As a result, design engineers spend significant time optimizing the battery management system and the thermal management of the entire battery pack. Nordson EFD helps dispense epoxies, UV-cure adhesives, thermal interface materials, and other types of structural adhesives within the battery pack.

Nordson EFD innovative piezoelectric jetting technology removes the barrier between speed and accuracy. The PICO Pμlse jet valve and PICO Toμch controller make it possible to dispense very exact, repeatable micro-deposits as small as 0.5 nL at up to 1000Hz continuous, with 1500Hz maximum bursts – an industry best.

The PICO Pμlse non-contact jet valve’s modular design makes it possible to jet low- to high-viscosity fluids onto any surface, including uneven and tough-to-reach substrates. Exchangeable parts provide versatility, making the valve adaptable to a wider range of applications, so it can meet changing production demands. Its innovative tool-free latch mechanism allows for easy removal of the fluid body for faster serviceability and maintenance – reducing downtime and increasing productivity. Variable stroke, improved close time, and faster full stroke open time makes Pμlse one of the most robust jet dispensing valves on the market.

The PICO Toμch controller features an easy-to-use intuitive touchscreen interface for precise control of the PICO Pμlse valve. Users can set extremely precise operating parameters, such as ramp open and close, and stroke control to fine-tune dispensing performance. Pulse time can be adjusted in increments as small as 0.01 ms. Better slope control delivers more repeatable deposits while preventing turbulence and air bubbles from entering the fluid – preventing deposit variation.

The PICO Pµlse jetting system provides the speed and accuracy needed to keep up with the throughput and quality assurance requirements in the battery cell and module dispensing applications.
