ADHESION SCREEN SYS, HIGH THRO

Milara Screen Printer precisely prints solders, adhesives, and polymers through stencil or screen to join or protect electronic assemblies. An automated water-jet apparatus was designed and fabricated at NDSU for screening microbial adhesion. The system consists of a robotic arm that is mounted on a stainless steel deck which can access coating array plates from one of three plate stacking hotels. The robotic arm inverts each well of an array plate over an offset, rotating nozzle that delivers a jet of water perpendicular to the coating surface. The duration and pressure of the water-jet are precisely controlled through a customized software program. Coating array plates are subjected to water-jet treatments after bacterial or algal incubation to facilitate removal of adherent biofilms.
