Today, the ultrafast and precise dosing of tiniest fluid volumes is key to many automated industrial applications, e.g. in electronics production when assembling components.
Industrial dosing procedures are very diverse, but they all have one thing in common: The high requirements for accuracy. These requirements must be met independently of environmental influences.
In the manufacture of microchips, industrial precision technology plays an essential role – soldering pastes must be dispensed ultrafast on the smallest electrical chips, which means fine tuning and the highest precision.
For example, in digital printing and inkjet procedures, ink (or another material) is applied ultrafast and precisely without contact onto the material being printed. In both applications, tiniest fluid volumes up to the picoliter range must be dispensed accurately.
Piezo elements with their compact size, speed, and their low level of energy consumption are suitable for reliably move and dose small liquid volumes in the range of a few hundred milliliters up to a few picoliters.
Piezo-driven dispensing systems can generate several thousand pico- to microliter droplets per second and with that reach a high throughput, which is becoming increasingly important due to the pressure of competitiveness.
