Abstract:
A substrate cleaner incorporated in the manufacture line for a printed wiring board to remove foreign particles deposited on the surface of the substrate. A carrier belt (3) carries the substrate (2) by loading its edge section. A suction roller (4) utilizes wetting property to suck foreign particles on the substrate surface. The foreign particles sucked by the suction roller (4) are transferred to an adhesive roller (5). The suction roller (4) maintains a cleaning effect for a long time. Since the edge section of the substrate (2) is mounted on the carrier belt, the surface of the substrate (2) is cleaned even loaded with an electronic component in the rear.
Abstract:
A compact reflow oven and cleaning apparatus combines in a unitary housing for both the reflow and cleaning function. This results in the saving of valuable floor space in the printed circuit board assembly areas. The unitary housing and control of temperatures in the reflow and cleaning areas facilitate the removal of contaminants before solidification of such contaminants.
Abstract:
A method and apparatus are disclosed for improving drying of a module, tooling, and solder stencils via the introduction of acoustic pressure waves and/or vibrational energy to the module, tooling, or solder stencils. The acoustic pressure waves may be created by a transducer where the waves are transferred to the module through air or a vibrational interface medium. The acoustic pressure waves impinge on the water droplets to atomize the droplets on the surface of the module and in the cracks, crevices and hard to reach areas of connectors and other components, without undesirable heat. The acoustic energy may further be used to assist in cleaning solder stencils within an automated screen printer.
Abstract:
The invention concerns a method for treating a part (2) formed by a support (3) whereon components are fixed, by melting a filler material, consisting in: placing the part (2) at a predetermined cleaning temperature higher than the boiling point of the part cleaning liquid; when the part (2) reaches the cleaning temperature, immersing it into a cleaning liquid. The invention is characterised in that the method consists in: placing the part (2) at a cleaning temperature less than the melting point of the filler material; and immersing the part (2) in the cleaning liquid the temperature of which is not less than its boiling point.
