Dot Dispensing
Precision dispensing of functional material
Dot dispensing is a digitally controlled, drop-on-demand process that precisely deposits discrete volumes of liquid material (“dots”), ranging from picoliters to microliters, onto substrates. It employs various methods such as piezoelectric or solenoid jet valves, pneumatic dispensers, positive-displacement pistons, and direct ink writing (DIW).
Dot dispensing applications span diverse fields, including microelectronics assembly (solder paste, conductive adhesives, underfill encapsulation), bioscience (microarrays, cell/biomaterial patterning, drug discovery), genomics, printed electronics, microfluidics, light displays, and flexible sensors.
