Abstract: A method of forming a meltable material at a joint between telescopingly engaged male and female elements, with the female element having a joint surface that surrounds a joint surface of the male element. The method includes the steps of: placing a ring of the meltable material around one of the male and female elements at a first location spaced from the joint; heating the male and female elements at the joint to a temperature at which the meltable material melts; sliding the ring of meltable material from the first location to a second location; with the ring of meltable material at the second location and the male and female elements of the joint at a temperature at which the meltable material melts, causing the meltable material to flow between the male and female joint surfaces; and cooling the male and female elements at the joint to solidify the meltable material between the male and female joint surfaces.

Abstract: A squeegee unit having a stirring squeegee and a leveling squeegee fixed thereto is rocked with the reciprocating operation of a transfer unit moving mechanism to cause the stirring squeegee and the leveling squeegee to approach the pan surface of a transfer unit on going and returning paths. Consequently, the stirring squeegee stirs a viscous fluid put on the transfer unit on the going path of the transfer unit and the leveling squeegee uniformly flattens the viscous fluid stirred on the going path to have a predetermined thickness on the returning path of the transfer unit, thereby forming a flat viscous fluid transfer surface on the transfer unit. By immersing the terminal portion of the electronic component in the viscous fluid transfer surface, the viscous fluid is transferred to the electronic component and the electronic component is then mounted in a predetermined mounting position.

Abstract: An apparatus joins bonding pads of a slider and lead pads of lead wires in a head gimbals assembly to improve efficiency, downsizing, and maintenance of solder-ball disposing devices, and solder-ball reflow devices for reflowing solder balls. The solder-ball disposing apparatus discharges solder balls from solder-ball discharging holes of a solder-ball feeder unit which are evacuated by a suction pad. An environmental space and an inert-gas supply portion for forming inactive atmosphere are formed on a table to eliminate an inert-gas supply unit from an optical unit, so that converged laser beams are directly radiated onto the solder balls.

Abstract: Methods and apparatus for replacing an old wire threaded through a flyer winder with a new wire are provided. A first end of the old wire is connected to a first end of the new wire. The wires may be connected by twining, clamping, welding or the like. A second end of the old wire that extends from one of the winder's flyers is then connected to a collection device, and the old wire is collected until the new wire has been threaded through the flyer winder along the same path traveled by the old wire. The collection device may be an armature or similar structure having recesses for collecting the old wire during wire change-over or replacement. Preferably the collection device is configured so that conventional coil lead connection operations may be used to expedite wire change-over or replacement.

Abstract: The disclosure is a plural process to perform a solder ball attaching process that corresponds to the final of a ball grid array package manufacturing process. For example, flux and solder balls are exactly attached on solder ball pads of base frames on which base tapes having a number of land pattern groups are adhered. In the above state, the base frames are inserted into an adjacent reflow device to make the solder balls be attached on the solder ball pads. After the flux of the solder ball pad, on which the solder ball is attached, is removed, the base frames are stored in containers. To perform the base frame storing process in a very small space, the transfer course of the base frames is in the form of loop.

Abstract: A solder jet apparatus is disclosed. The solder jet apparatus is a continuous mode solder jet that includes a blanking system and raster scan system. The use of the raster scan and blanking systems allows for a continuous stream of solder to be placed anywhere on the surface in any desired X-Y plane. This allows for greater accuracy as well as greater product throughput. Additionally, with the raster scan system, repairs to existing soldered surfaces can be quickly and easily performed using a map of the defects for directing the solder to the defects.

Abstract: A process for promoting fluxless soldering of a mass of bulk solder having a bulk ratio of a first metal to a second metal, such as lead-enriched solder that has significantly more lead than tin. The process comprises exposing the bulk solder to energized ions of a sputtering gas in the presence of a halogen, such as fluorine, and forming a surface layer having a desired surface layer ratio of the first to the second metal that is less than the bulk ratio, the surface layer further comprising an uppermost surface film containing the fluorine or other halogen. After the solder exposure and surface-layer formation, the process may further comprise electrically joining the solder to a surface without using externally-applied flux. This process enables the joining step to be performed at less than 300° C., at approximately 180° C.

Abstract: A disposable solder receiving capsule for a hand held vacuum solder extracting desoldering tool is formed of an outer tube which is closed at one end by a porous filter and has an opening at its opposite end, and a hollow solder collection chamber part, having a tubular member with an open end and which is closed with respect to the passage of solder therethrough at an opposite end, forming a solder receiving space within it. The solder collection chamber part is concentrically positioned within the outer tube with an air plenum disposed between the closed end of the chamber part and the filter and with at least one air channel extending the length of solder collection part for providing a path for gases entering the open end of the outer tube to the plenum and the filter that is separated from the solder receiving space. For facilitating solder reclamation, the capsule can be formed entirely of materials which are shape-sustaining when exposed to a temperature of 400° F., are not reactive with either solder and flux, which will burn with little or no residue at a temperature less than 800° F. A desoldering tool for use with the capsule has a detachable, tubular capsule holding part that is open at each of its opposite ends for enabling a solder receiving capsule received in it to be removed from one of the end of the holding tube by pushing another soldering capsule into the opposite end of the holding tube when the detachable holding part is detached from the body of the desoldering tool. In a most preferred embodiment, the tool is designed so that solder cannot be drawn into it if the capsule has not been inserted or has been inserted incorrectly.
