A jet solder bath for performing soldering by jetting molten solder to bring the molten solder into contact with a substrate is provided with a primary jet nozzle that jets the molten solder by a first jet pump, as a first jet nozzle, and a secondary jet nozzle, as a second jet nozzle, which is arranged at a downstream side of the primary jet nozzle along a carrying direction of the substrate and jets the molten solder by a second jet pump. The primary jet nozzle includes a first nozzle body, and a first solder-flow-forming plate that is provided at an upper end of the first nozzle body and has a plurality of jet holes, and the secondary jet nozzle includes a second nozzle body and a second solder-flow-forming plate that is provided at an upper end of the second nozzle body and has a plurality of jet holes.

The present application provides an apparatus for automatically clearing away residual solder paste, comprising: a working platform for bearing a solder paste tub accommodating a solder paste nozzle, the solder paste nozzle having a solder paste nozzle mouth, the working platform having a solder paste through-hole for accommodating the solder paste nozzle mouth; and a gas channel disposed in the working platform, the gas channel comprising a gas inlet and a gas outlet, the gas inlet being configured to be in communication with a cleaning gas source, and the gas outlet being configured to blow gas towards the solder paste nozzle mouth accommodated in the solder paste through-hole, thereby cutting solder paste remaining at the solder paste nozzle mouth.

The high-efficiency soldering apparatus for a winding head of a flat-wire motor includes a support base, a solder tray, a solder spot isolation and limit plate, a shaft lever and a movable tray. The solder tray is provided at the center of the support base. The solder spot isolation and limit plate is provided on the solder tray. The shaft lever is provided on the support base. The movable tray is provided on the shaft lever. The movable tray is located above the solder tray. The movable tray moves vertically along the shaft lever. A stator is placed at the center of the movable tray, and a winding head of the stator extends below the movable tray.

The present application provides an apparatus for preventing solder paste dripping, comprising: a working platform support apparatus; a working platform connected in a fixed manner to one end of the working platform support apparatus, the working platform being used to bear a solder paste tub comprising a housing, with a solder paste nozzle being accommodated in the housing, the solder paste nozzle being mounted on the working platform, so that the solder paste tub is borne in an inverted manner on the working platform by means of the solder paste nozzle, with the housing being capable of moving relative to the solder paste nozzle so as to extrude solder paste accommodated in the solder paste tub from the solder paste nozzle; and a holder, the holder being connected to the housing of the solder paste tub and located above the working platform, and the holder being slidably connected to the working platform support apparatus, so that the holder can move downward as the amount of solder paste in the solder paste tub decreases, to adjust the relative position of the solder paste nozzle and the housing.

Disclosed techniques compensate for variable forces applied to a brazing head in order to more accurately maintain application of a desired lateral force by a brazing wire, filling wire or tracking finger extending from the brazing head to a component. Orientation of the brazing head is determined relative to gravity and the angle of a movable arm of the brazing head relative to a support body of the brazing head. A lateral force value measured by a lateral force sensor is adjustable based on the determined orientation of the brazing head and the determined angle of the arm relative to the support body in order to provide a corrected or adjusted lateral force value. At least a portion of the brazing head is repositioned relative to the component if the corrected lateral force value deviates from a predetermined value.

A ball disposition system includes a ball adsorption device, and a ball guide plate providing a ball guide hole. The ball adsorption device includes an adsorption plate providing an adsorption hole extending in a first direction, and a pin extending in the first direction, a portion of the pin inserted in the adsorption hole. The ball guide plate is located beyond the adsorption plate in the first direction.

This flux transfer apparatus (10) comprises: a stage (12) having a recessed portion (13) for collecting flux (51); a flux pot (20) which is an annular member having a through hole (21) into which the flux (51) is introduced, which reciprocates along a top surface (14) of the stage (12) to supply the flux (51) that has been introduced into the through hole (21) into the recessed portion (13), and which levels off the top surface of the flux using a bottom surface (22); and a cooling mechanism (30) for cooling the stage (12). By this means, a rise in the temperature of the stage in the flux collecting apparatus is suppressed.

A method for depositing a material to join two surfaces of an electronic assembly includes determining, using dimensions of a pad area of a substrate, a deposition pattern for the material that extends across the pad area of the substrate. The method further includes creating a tool to deposit the material in the deposition pattern that extends across the pad area of the substrate.

A liquid agent supply device includes: a holder that holds a board; a supply head including a plurality of nozzles for supplying a liquid agent to a plurality of supply positions on the board held by the holder are arranged; and a supply head mover that relatively moves the board and the supply head, wherein the supply head mover relatively moves the board and the supply head according to a first movement method in which the board and the supply head relatively move along a specific direction determined regardless of supply positions among the plurality of supply positions, in a supply range including the plurality of supply positions.
