摘要： Vertically displaceable green sheet support fixtures are borne by respective horizontally movable carriages traveling on common rails between respective dual loading stations and a common unloading station, through separate intermediate screening stations, with the carriages movable in opposite directions and out of phase stationwise. The carriages have fixedly coupled thereto, horizontally movable trailers which bear trays of stacked green sheets for selective transfer of the uppermost green sheet to a loading head at the loading station while the carriage borne fixture itself is at a screening station for paste screening of a prior transferred green sheet. Masks employed in screen printing at the screening station are removed from the screening station console and placed in a cleaning chamber for solvent removal of residual screening paste and are air dried prior to return to the screening station console. During cleaning of a dirty mask, a second clean mask is automatically presented at the station to eliminate throughput-loss. The fixture is vertically displaceable on the carriage and its height incrementally varied depending upon green sheet thickness variation. Accelerated vertical separation of the carriage borne green sheet from the mask is effected subsequent to initial slow incremental separation therebetween.

摘要： A horizontally movable slide bears a two section, continuously extending horizontally inclined, steep and shallow sloped cam slot controlling the vertical rise and fall of a cam follower driven support fixture for supporting a ceramic green sheet in underlying contact with a stencil mask in an automatic MLC screening machine. An apertured positioning flag moves horizontally with the slide and past a vertical height digital position encoder assembly and a mask separate encoder assembly. The positioning encoder assembly provides an electrical signal for controlling an actuator mechanism causing slide movement, indicative of the desired final positioning height of the green sheet relative to the mask when the fixture is moving towards the mask. When the actuator mechanism drives the slide in the opposite direction, to lower the green sheet from the mask, the mask separate encoder assembly produces a signal, in response to common positioning flag movement in the opposite direction with the slide to effect a change in speed of the actuator mechanism. This provides slow initial separation of the green sheet from the mask and final removal of the fixture from screening height, at a much more rapid rate.

摘要： A method and apparatus permitting accurate and repeatable steps of location and alignment of flimsy sheets during their transfer. A preferred embodiment comprises a sheet handler and method for aligning unfired ceramic green sheets used in multi-layer ceramic semiconductor packages. The thin flexible sheets are square or rectangular in shape and are provided with holes accurately punched in each corner thereof for alignment purposes. The sheets are moved by a vacuum input transfer head into orientation with a porous registration surface of an alignment fixture. The sheet is then trapped between opposed pressure zones emanating from the input transfer head and through the porous registration surface, respectively. With the sheet stabilized between the pressure zones four bullet-nosed alignment pins are raised from the registration surface into contact with the holes in the corners of the green sheet, thereby accurately aligning the sheet with respect to the alignment fixture. The input transfer head is then withdrawn and an output transfer head picks up the aligned sheet via vacuum means and transfers it to other processing locations. In an alternate embodiment the pressure zones are created between the output transfer head and the registration surface of the alignment fixture.

摘要： A vacuum pick up and transfer head adapted for handling flimsy sheets of material such as spacer sheet and uncured ceramic sheet commonly referred to as green sheet. The vacuum transfer head is of generally rectangular configuration having a sheet contacting lip having vacuum slots formed through the periphery thereof to hold the sheets in place by vacuum pressure. The center of the sheet contacting face is recessed whereby, with a sheet in place and acting as a diaphragm, a central vacuum chamber is also defined. A series of check valves are provided to control application of vacuum and positive pressure to the green sheet for picking the sheet up, retaining it and stripping it. A plurality of probes are provided in the handling head, adapted to selectively project through the sheet contacting surface for detecting green sheet and/or spacer sheet utilized inbetween layers of green sheet. These probes also can act as positive strippers when the head enters a green sheet spacer tray in the process of removing a sheet of spacer or green sheet.

摘要： The flexible disk envelope is formed from a flexible plastic prepunched blank having two connected sections. One section of the blank has side flaps extending from the opposite side edges. The blank is folded about an end of a mandrel so that the side flaps extend beyond the side edges of the mandrel. The mandrel holds the plastic blank section having the flaps extending therefrom against the bottom surface of a plate. The mandrel has raised edge portions running along the side edges on the outward facing surface thereof. The side flaps are folded around the adjacent edge of the mandrel in an outward folding direction by folding blades which are driven about pivot means to guide the folding blades in an arcuate path. Stops are provided which stop the arcuate motion of the folding blades and allow the upward motion means associated with the pivot means in response to the drive means to cause compression of respective flaps against the adjacent blank section and mandrel by said folding blades beyond said raised edge portions providing overfold zones Infra-red heating means are operable through windows in the folding blades adjacent the side folds to provide annealing of the fold thereby relieving any stresses therein.
