An injection apparatus for injection material is disclosed. The injection apparatus includes a tank for storing material. The injection apparatus further includes a head body that has a surface for contacting a substrate and an opening part opened at the surface for discharging the material in fluid-communication with the tank. The injection apparatus further includes a member connected to the opening part, in which the member allows gas to flow into and flow out from the opening part.

The invention describes the assembly and construction method for anodes used in the electrolytic processes. It is made up of a copper bus bar (1) where the plate shall be inserted (3). It has a rough surface previously milled to form a groove (2), which is, approximately, 0.12 mm thicker than the thickness of the plate; approximately, 19 mm deep. Such copper bus bar (1) is first subject to a process mechanical/chemical or electrochemical process aimed to significantly increase its roughness, between 0.01 mm and 0.5 mm, preferably 0.15 mm, by using mechanical processes, such as sand blasting or grinding, preferably grinding with blasting material made of various metals or using glass balls/copper slag or chemical corrosion by using oxidant chemical agents or anodic electrolytic corrosion aimed to finally improve bonding between the copper bar.

A method of manufacturing a printed circuit board assembly includes providing a circuit board, positioning a plurality of components including at least one thermally-sensitive component having a maximum temperature threshold on the circuit board, positioning a customized protective heat shield on the thermally-sensitive component, exposing the circuit board (having the thermally-sensitive component disposed thereon and the customized protective heat shield disposed on the thermally-sensitive component) to a high-temperature environment wherein temperatures exceed the maximum temperature threshold of the thermally-sensitive component, and removing the customized protective heat shield from the thermally-sensitive component. Customized protective heat shields are also provided.

A soldering apparatus 100 including: a chamber 120 configured to contain solder and include an opening 122 configured to discharge the solder in a bottom surface or a side surface; a pump 140 configured to transport the solder to the chamber 120; and an inner bath 160 configured to communicate with the opening 120 and perform soldering using the solder fed through the opening 120.

A wave soldering machine includes a housing and a conveyor configured to deliver a printed circuit board through the housing. The wave soldering machine further includes a wave soldering station coupled to the housing. The wave soldering station includes a reservoir of solder material, and a wave solder nozzle assembly configured to create a solder wave. The wave solder nozzle assembly has a nozzle core frame, a solder distribution baffle secured to the nozzle core frame, and a sliding plate that together define a nozzle. The sliding plate is movable with respect to the nozzle core frame between a close proximate position in which the nozzle is configured to produce a reduced width solder wave through the solder distribution baffle and a spaced apart position in which the nozzle is configured to produce an extended width solder wave through the solder distribution baffle.

Provided are a jet solder level confirmation jig and a method of handling the same, which allow the level of the jet wave of the molten solder to be accurately confirmed. A jet solder level confirmation jig is provided with a level confirmation unit for confirming a level of a jet wave of molten solder, a holding unit that holds the level confirmation unit, a notifying unit that notifies the level of the jet wave of the molten solder; and a bridge member having a length so as to be able to form a bridge in an upper part of a jet solder bath housed within a housing, the bridge member supporting the level confirmation unit in the upper part of the jet solder bath. The notifying unit is connected to a power supply unit of a jet soldering device.

An injection-molded solder (IMS) tool assembly apparatus, the apparatus including an IMS tool for dispensing a molten material via a round extrusion part to coat an inside or an outside wall of a pipe (and a chiller for providing cooling water to flow through an inside of the pipe.)

Disclosed are a method and a system for tin immersion and soldering of a core wire which includes: inserting a core wire row into molten tin vertically; moving the each core wire in the molten tin along a direction perpendicular to the core wire row to remove carbonized matter from each core wire on a moving direction side; pulling the each core wire out of the molten tin; and performing alignment, such that the inner core conductor of the each core wire on the moving direction side contacts with a bonding pad. According to the technical solution of the present disclosure, the carbonized matter on the core wire that aligned facing the bonding pad is removed, such that the temperature transfer effect of the automatic soldering is improved, the yield of the automatic soldering is improved, and the consistency and the yield of the automatic soldering are more stable.
