Abstract:
A detachment apparatus for detaching at least one component (120) from a circuit board (125) can include a shaft (105) configured to rotate about a central axis, at least one lever (110) having a first end and a second end, the lever being attached to the shaft at the first end, and a hook (115) attached to the second end of the lever. Rotation of the shaft causes the hook to come into contact with the component on the circuit board, and the hook is configured to separate the component from the circuit board.
Abstract:
The invention relates to a method for assembling electrical connector pins on a support (20) in the form of a card, comprising: introduction of the pins (31) into individual locations (22) on the first face (201) of the support, the pins forming at least one comb-like alignment (31A, 31B) on the second face (202), arrangement of the solder on the second face, around the pins and heating the comb by means of a hot gas flow to carry out the soldering. The method is characterised in that the gas flow is guided such as to pass at least in part between the pins (31) forming the comb (31A, 31B) from one side of the comb then, after crossing the comb, the flow is diverted away from the support. A nozzle with a guide channel and a deflector by means of at least which the flux is diverted is particularly used. The wall of the channel is arranged in line with the comb formed by the pins such as to reduce the part of the flux not used for the heating.
Abstract:
The invention relates to a method of preparing a universal detacher for electronic components, comprising a desoldering paste for removing any type of electronic component. The invention comprises the alloying of tin, lead and mercury, together with zinc chloride, potato starch, petrolatum, camphor, eucalyptus and a colouring agent, which produces a desoldering paste for electronic components. The inventive desoldering paste can be used to retrieve any piece of electronic circuitry in full and without causing any damage.
Abstract:
A method comprises the steps of heating chucked waste printed board to separate and collect solder from the waste printed-board, blowing the printed board to separate and collect surface-mounted components from the printed board, vibrating the printed board to separate and collect through-connection mounted components from the printed board, scrubbing the surface of the printed board to separate and collect residual mounted components, and collecting the printed board from which the mounted components have been separated. As a consequence, it is possible to reuse the collected printed board and a part of the collected components. Since no chemical treatment is performed, there is no fear of generating secondary pollution. Besides, substances that are not recyclable after the processing is hardly produced. Since the steps can be executed continuously within a short time, the process efficiency is extremely excellent.
Abstract:
The invention relates to a method for separating a metal part (11) from a ceramic part (12), which are joined at a connecting face (13) within a modular hybrid component (10), especially of a gas turbine. The method is characterized in that said component (10) is subjected to a reducing atmosphere (A2) in a gaseous process at elevated temperatures (T2) to dissolve the connection between said metal part (11) and said ceramic part (12), especially by dissolving the ceramic part itself.
Abstract:
The invention relates to a disordering device(1) which comprises an absorbing element and a heating element (9). The absorbing element is arranged in such a way that the part thereof is heated in order to form an active part which contacts a solid weld associated to a surface. Said absorbing and heating (9) elements are arranged on a main body (6) in such a way that they are movable in relation to each other. Said device also comprises a motion control unit which makes it possible to modify the relative positioning of the absorbing and heating elements in order to heat the yet unused part of the absorbing element.
Abstract:
The invention relates to a method for ablating a plurality of raised points of contact (11, 12, 13, 17, 18) that consist of a metal, such as tin or indium, that is meltable above a first temperature, or an alloy thereof, such as tin-containing solder, silver-containing solder or lead-containing solder, said points of contacts being distributed across a substrate (10). It is also possible to produce convex domes on a plurality of metal support segments that are located on one of the surfaces of a substrate. The aim of the invention is to reduce production costs, especially to remove a soldered spot once produced that turns out to be defective. To this end, a plurality of the raised points of contact (11, 12), especially substantially all points of contact, are at least substantially melted off from the substrate (10) by touching them with a molten metal (30, 31, 32). Between the substrate (10) and the support segments (9) distributed across its surface and a surface of the molten metal (30, 31, 31) an organic fluid may be present. Said fluid is present as a superficial layer (40, 41) only that evaporates off the substrate surface (10a) once the convex domes (60) are formed.
Abstract:
A portable electric soldering tool (20) includes a housing (22) having a handle portion (24) and a power head portion (26). A power cord (28) connects the tool (20) to a source of power via a terminal block (36). A main power switch (30) activates the tool (20). A trigger switch (32) in the handle portion (24) intermittently activates a vacuum device (120). A heating assembly (40) includes a heating rod mounted with the heating tip (44) extends from a forward end of the power head (26). The heating rod having an axial bore with a stainless steel lining to prevent solder from building up in the heating rod. A heating coil heats the heating rod. The heating rod directs melted solder into an extraction tube in which a curved wafer is disposed to collect the solder. A diaphragm pump is mounted in the power head and has an oblong piston head, which is mounted with the long axis aligned on a longitudinal axis of the tool, which facilitates a more compact unit.
