The substrate treating apparatus includes a guide plate provided below a substrate carrying plane along which a bottom surface of the substrate is to be carried; and treating liquid supply means having a first treating liquid supply member for supplying a treating liquid to a clearance defined between the bottom surface of the substrate carrying plane and the guide plate.Type: GrantFiled: June 3, 1997Date of Patent: March 16, 1999Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Mitsuaki Yoshitani

Patent number: 5876499Abstract: An improved horizontal solder leveller for applying molten solder to boards while removing residual flux therefrom include a single pair of upper and lower solder sparge bars with outlet nozzles arranged so as to direct solder jets from one sparge bar toward the jets from the other sparge bar in the gap formed between the sparge bars. The gap between the sparge bars and the speed of the solder jets is sufficient to remove residual flux from a board passing therethrough as molten solder is applied to the board. An oil guide is included that directs oil to form curtains immediately upstream and downstream of the sparge bar gap to form a barrier to air flow in the gap. An oil trough upstream and downstream of the lower sparge bar limits the vertical extent of the oil curtains. Preferably a pair of castellated infeed rollers and outfeed rollers are used to move boards through the leveller.Type: GrantFiled: September 9, 1996Date of Patent: March 2, 1999Inventor: Peter P. Lymn

Patent number: 5733376Abstract: Apparatus for sequentially coating opposite major surfaces of a workpiece such as a printed circuit board and wherein the amount of manual handling is significantly reduced. Boards are arranged end-to-end preferably in closely spaced fashion upon a conveyor having an adjustable drive. First and second spray assemblies provide a low pressure spray having a substantially oval-shaped spray pattern and are arranged upon guide tracks to move in a reciprocating fashion in a direction transverse to the direction of movement of the conveyor for coating opposing surfaces of the workpiece. The speed of movement of the spray heads and the extreme ends of the range of movement are adjustable by controlling the operation of a drive motor to create a substantially Z-shaped spray pattern on the workpiece with the size of the Z-shaped pattern being a function of the conveyor speed spray head assembly, drive speed and range of movement of each spray head assembly.Type: GrantFiled: August 1, 1994Date of Patent: March 31, 1998Assignee: Argus InternationalInventor: Bernard J. Costello

Patent number: 5720813Abstract: An apparatus for processing a flexible panel along a feed path is disclosed. In detail, the apparatus includes a platen member for receiving pressurized fluid and directing same through a plurality of jets in a path transverse to the feed path as the panel travels thereunder. First and second roller shafts having rollers thereon, in a spaced relationship, are located upstream and downstream of the platen member, respectively. The roller shafts are coupled to a drive system for rotating the rollers such that the panel is advanced along the feed path from the upstream sisde, under the platen, to the downstream side. The platen member includes first wing portions extending between adjacent rollers of the first roller shaft for stripping the panel from the rollers of the first roller shaft and providing support for the panel as it passes under the platen member and into contact with the pressurized fluid.Type: GrantFiled: June 7, 1995Date of Patent: February 24, 1998Assignees: Eamon P. McDonald, Seamus P. McDonaldInventor: Eamon P. McDonald

Patent number: 5679155Abstract: A method and apparatus for depositing solder on the terminal pads (10) of printed circuit boards (12) in which a solder resist layer (16) or layers (16, 17) having a thickness corresponding to the desired solder height border the pads. Molten solder from a reservoir (58) is directed by nozzles (72) against the sides of the board (12) to fill the cavities extending above the terminal pads while the board (12) is moving via a conveyor mechanism relative to the reservoir (58). The cavities when filled with molten solder are covered by a suitable element such as a flexible belt (52) or roller. The molten solder within the covered cavities is then cooled below its solidification point and the covering element removed. If desired, part or all of the solder resist layer (16) or layers (16, 17) may then be stripped from the board (12) to leave solder pads extending above the surface of the board (12).Type: GrantFiled: May 18, 1995Date of Patent: October 21, 1997Assignee: Velie Circuits, Inc.Inventor: Larry N. Velie

Patent number: 5669974Abstract: A continuous spray coating apparatus and process generally comprises a housing defining a closed coating chamber, the coating chamber having inlet and outlet openings. Automatic doors are provided to cover the inlet and outlet openings, and the opening and closing of the doors is selectively controlled such that only one of the doors will be open at any one time during the spray coating operation. The introduction of the coating composition into the chamber creates a predetermined atmosphere within the chamber which is substantially saturated with constituents of the coating material, and by means of the automatic doors and control thereof, introduction of air from the outside atmosphere into the chamber is substantially prevented to maintain a predetermined atmosphere within the chamber.Type: GrantFiled: June 7, 1995Date of Patent: September 23, 1997Assignee: Dana CorporationInventors: Salome J. Cueller, Robert J. Radawski, Michael R. Barth, Jack V. Jerraid, John A. Keyes, Earl V. Gleason

Patent number: 5662968Abstract: In a method of painting a building board being conveyed on a conveyor by means of a spray painting apparatus so that a plurality of colors of gradated or shaded patterns are formed, a plurality of spray guns are connected to a plurality of paint supply systems supplying different colors of paint, respectively. The spray guns are arranged in parallel to a direction in which the building board is conveyed. With the spray guns being reciprocated in a direction crossing the direction in which the building board is conveyed, each of the spray guns is intermittently turned on and off so that the paints of colors different from one another are sprayed from the spray guns onto the surface of the building board. The relation between a speed of the reciprocation of each spray gun and a speed of conveyance of the building board is expressed by L.ltoreq.P.times.Type: GrantFiled: July 23, 1996Date of Patent: September 2, 1997Assignee: Nichiha CorporationInventor: Takahiro Yamaguchi
