    摘要: This invention is a method of manufacturing a multi-layer printed wiring board including an internal layer circuit forming step, a outer layer circuit forming step, and a solder resist forming step. In the solder resist forming step, the surface of a board subjected to the outer layer circuit forming step is coated with a photosensitive solder resist material, the solder resist material is coated with a photosensitive film; a light shielding mask is formed by irradiating a laser beam on the photosensitive film according to a formed pattern of the solder resist, the solder resist material is exposed by using the light shielding mask, the light shielding mask is removed, and the solder resist material which is not exposed is removed.

    摘要: An apparatus and method are provided for processing an item by distributing a liquid onto a surface of the item. The apparatus includes a conveyor which defines an undulating path which varies in vertical position relative to the direction of movement of the item conveyable along the path. Thus, the path has at least one apex at a location of the path higher than other locations in the direction of movement along the path. A sprayer is operable to spray the liquid onto the surface of the item at a location that is substantially aligned to the apex of the path.

    摘要: A manufacturing system for printed wiring boards divides printed wiring boards scheduled to be manufactured into non-fractional and fractional groups depending on the content of an order remainder list. The printed wiring boards categorized as non-fractional are panelized having the same shapes while the printed wiring boards categorized as fractional are grouped corresponding to manufacturing conditions thereof. Then, each group of the printed wiring boards are panelized with different shapes in a predetermined manufacturing block. Consequently, the generation of incidental products or the waste of material can be prevented.
