Abstract:
Um ein flächiges Behandlungsgut (21) in einer Anlage zur chemischen und/oder elektrochemischen Behandlung des Behandlungsgutes (21) zu transportieren, in der das Behandlungsgut (21) in einer Transportebene in einer Transportrichtung (5) transportiert wird, werden an dem Behandlungsgut (21) Haltemittel (22, 25) angebracht. Die Haltemittel (22, 25) halten das Behandlungsgut (21) an mindestens zwei Punkten eines Randbereiches des Behandlungsgutes (21), der beim Transportieren des Behandlungsgutes (21) entlang der Transportrichtung (5) gerichtet ist. Die Haltemittel (22, 25) sind lösbar mit einer Transportvorrichtung (41) gekoppelt, die die Haltemittel (22, 25) in der Transportrichtung bewegt, um das Behandlungsgut (21) zu transportieren. Wenigstens während eines Abschnitts des Transportierens des Behandlungsgutes (21) wird auf einen Bereich des Behandlungsgutes (21), beispielsweise auf die Längsrandbereiche, eine Kraft (6, 7) mit einer Kraftkomponente, die in der Transportebene liegt und quer zu der Transportrichtung (5) gerichtet ist, ausgeübt.
Abstract:
An apparatus and method for fabricating electronic devices on a polymeric substrate provide for positionally constraining a polymer substrate on a platen, and heating the constrained polymer substrate to at least a glass transition temperature of the polymer substrate. A heat processable ink is applied to the constrained polymer substrate to form at least a portion of a layer of an electronic device thereon.
Abstract:
A monitoring system (100) for monitoring fluid in a fluid supply vessel (22, 24, 26, 28, 108) during operation including dispensing of fluid from the fluid supply vessel. The monitoring system includes (i) one or more sensors (114, 126) for monitoring a characteristic of the fluid supply vessel or the fluid dispensed therefrom, (ii) a data acquisition module (40, 132, 146) operatively coupled to the one or more sensors to receive monitoring data therefrom and responsively generate an output correlative to the characteristic monitored by the one or more sensors, and (iii) a processor (50, 150) and display (52, 150) operatively coupled with the data acquisition module and arranged to process the output from the data acquisition module and responsively output a graphical representation of fluid in the fluid supply vessel, billing documents, usage reports, and/or resupply requests.
Abstract:
In a screen printing apparatus for contacting a lower surface of a mask plate (12) with a substrate (6) and moving a squeezee (16) in a sliding motion on an upper surface of the mask plate (12) thereby printing a paste onto the substrate, mask bend preventing members (117) are mounted on conveying rails (7) at front and rear parts of clamp members (8) clamping the substrate (6) in a Y-direction, and, at a mask separating operation after printing, the substrate is lowered while the lower surface of the mask plate (12) is supported by the clamp members (8) and the mask bend preventing members (117). Thus the mask separation can be achieved in a state where the mask plate (12) is supported from below on four sides of the substrate (6) and is thus prevented from a downward bending, and a satisfactory mask separating property can be ensured over the entire substrate (6).
Abstract:

A system and method for reflowing solder to interconnect a plurality of electronic components (24) to a substrate (12) is disclosed. The system includes an oven for preheating the substrate (12) and the plurality of electronic components (24) disposed thereon, a supplemental heat source disposed in the oven for providing additional heat energy to reflow the solder (72), a pallet (14) for supporting the substrate (12), wherein the pallet (14) has at least one internal cavity (40), and a phase-transition material (42) disposed within the cavity (40) for absorbing heat from the pallet (14).
Abstract:
A method for rapidly and accurately stripping certain areas (10, 11) of a printed circuit (6), both on conductors (3) and next to them. The areas to be stripped (10, 11) on a blank covered entirely or in part with an insulating coating (4, 5) are machined with a machining head having one or more laser beams controlled by a computer which receives the coordinates of said areas. The strength of the beam is modulated differently for the conducteurs (3) and the areas next to them, as well as when piercing the circuit or cutting around its edges. The method can be used for the manufacture of flexible printed circuits.
