This pressure can be used to agitate liquid, displace surfaces or propel objects without physical contact or mechanical hardware, and eject or deploy droplets. Depositing solder pastes Benefits Nonintrusive-ARP permits us to manipulate liquids inside hermetically sealed containers. Because acoustic energy is transmitted through intervening barriers, the acoustic transducers are safely isolated from the liquid. This eliminates the need for mechanical seals and bearings that would be attacked by reactive or abrasive liquids. Precise liquid control-Burst modulation permits precise power control.
High frequency provides precise focusing and permits manipulation to microscopic levels.
These techniques let the user precisely deposit small amounts of material on demand. Precise droplet placement can eliminate masking and screening steps for applying coatings. Maskless coating eliminates manufacturing steps and tooling and reduces chemicals, which makes the process inherently cleaner. Precise control of these effects allows us to manipulate liquids or objects suspended in the liquid and, therefore, move them exactly where we want them. Since ARP can be transmitted through intervening barriers, it can manipulate liquid in sealed containers.
