Publication number: 20080192089Abstract: The present teachings relate to a printhead maintenance station for an industrial printing apparatus which is used to prevent clogging of the printhead, particularly during periods in which the printheads are idle. The maintenance station includes a capping station which has sockets for keeping the printheads moist and a blotting station for cleaning any residual printing fluids prior to carrying out a print function.Type: ApplicationFiled: April 25, 2006Publication date: August 14, 2008Applicant: LITREX CORPORATIONInventors: David Albertalli, Robert D. Taff, Oleg N. Gratchev

Publication number: 20080170089Abstract: According to the present disclosure, a printer apparatus may include a chuck configured to support a substrate thereon, a rail spaced apart from the chuck, a printhead carriage frame coupled to the rail, and a printhead carriage coupled to the printhead carriage frame. The printhead carriage may include a printhead and an actuation mechanism. The actuation assembly may be coupled to the printhead carriage and may be selectively engagable with the printhead for selective displacement of the printhead relative to the printhead carriage.Type: ApplicationFiled: April 25, 2006Publication date: July 17, 2008Applicant: LITREX CORPORATIONInventors: David Albertalli, Paul A. Parks, Scott D. Slade, Roy M. Patterson

Publication number: 20080151270Abstract: A drop analysis/drop check system allows a plurality of printheads to remain stationary during analysis to emulate operation of an actual piezoelectric microdeposition system. The system provides accurate tuning of individual nozzle ejectors and allows for substrate loading and alignment in parallel with drop analysis/drop check. The drop analysis/drop check system includes a motion controller directing movement of a stage, a printhead controller controlling a printhead to selectively eject drops of fluid material to be deposited on a substrate, and a camera supported by the stage for movement relative to the printheads. The camera receives a signal from the motion controller to initiate exposure of the camera and captures an image of the drops of fluid material ejected by the printheads. A light-emitting device includes a strobe controller that receives a signal from the camera to supply light to an area including the liquid drops during camera exposure.Type: ApplicationFiled: April 25, 2006Publication date: June 26, 2008Applicant: LITREX CORPORATIONInventors: David Albertalli, Robert G. Boehm Jr, Oleg N. Gratchev, James N. Middleton, Perry West

Patent number: 7270712Abstract: A microdeposition system (20) and method deposits precise amounts of fluid material onto a substrate. A microdeposition head (50) includes a plurality of spaced nozzles. A positioning device controls a position of the microdeposition head relative to the substrate. A controller (22) includes a positioning module that communicates with the positioning device and that generates position control signals for the positioning device. A nozzle firing module communicates with the microdeposition head (50) and selectively generates nozzle firing commands to define features of at least one layer of an electrical device, such as resistors, traces and capacitors on a printed circuit board, polymer light emitting diodes, and light panels.Type: GrantFiled: May 31, 2002Date of Patent: September 18, 2007Assignee: Litrex CorporationInventors: Charles O. Edwards, David Albertalli, Howard Walter Bielich, James Middleton, Scott R. Bruner

Patent number: 7244310Abstract: A microdeposition system (20) and method deposits precise amounts of fluid material onto a substrate. A microdeposition head (50) includes a plurality of spaced nozzles that fire droplets having a deposited width when deposited on the substrate. A positioning device moves the microdeposition head (50) relative to the substrate at a head speed. A controller (22) generates over-clocking signals at a rate that is substantially greater than the head speed divided by the droplet width to improve resolution. The controller (22) includes a positioning module that generates position control signals for the positioning device. The controller (22) includes a nozzle firing module (114) that generates nozzle firing commands based on the over-clocking rate to fire the nozzles to form droplets that define features on the substrate.Type: GrantFiled: May 31, 2002Date of Patent: July 17, 2007Assignee: Litrex CorporationInventors: Charles O. Edwards, David Albertalli, Howard Walter Bielich, James Middleton

Patent number: 7160105Abstract: A temperature controllable vacuum chuck includes a mounting bracket, a porous plate, a heating element, and a temperature sensor. The porous plate is mounted to the mounting bracket and is configured for securing a substrate to the vacuum chuck when air is suctioned out of the vacuum chuck. The heating element is attached to the bottom of the porous plate and uniformly heats the porous plate, thereby heating any substrate mounted on the vacuum chuck and enabling control over the cure rate of fluid materials deposited on the substrate. The temperature sensor measures the temperature of the porous plate so that it can be adjusted when desired with a user controllable temperature control component.Type: GrantFiled: May 31, 2002Date of Patent: January 9, 2007Assignee: Litrex CorporationInventors: Charles O. Edwards, David Albertalli, Oleg Gratchev

Publication number: 20060165900Abstract: A microdeposition system microdeposit droplets of fluid material to define a feature pattern on a substrate. The feature pattern for the substrate is defined. A mask is created for the feature pattern that reduces a density of defects that occur due to a malfunctioning nozzle of the microdeposition head. The droplets of fluid material are microdeposited onto the substrate based on the mask to define subfeatures of the feature pattern. One of the nozzles of the microdeposition head is assigned to each of the sub-features in the feature pattern. The nozzles may be assigned randomly or using other functions. The assigned nozzles in the mask are assigned to one of a plurality of passes of the microdeposition head.Type: ApplicationFiled: November 27, 2002Publication date: July 27, 2006Applicant: LITREX CORPORATIONInventors: Charles Edwards, David Albertalli
