An introduction to a low corrosive, cost-effective aluminum brazing filler metal.

However, AlF3-KF solder has a significant drawback: its melting point is too high. Therefore, it is necessary to study a new type of aluminum brazing filler that has a low melting point, is non-corrosive, is cost-effective, and is suitable for flame brazing.

A method for producing a low melting point and easily promoted aluminum brazing filler.

In addition, the high content of csf in the alf3-csf binary flux, where csf is a precious metal salt with high cost, leads to high brazing costs for aluminum alloy honeycomb panels, limiting its application promotion. In view of the above issues, there is an urgent need to develop an aluminum brazing filler with a low melting point, low cost, and high compatibility with the melting point of zinc-aluminum brazing materials.

Introduction to a method for making copper solder paste for brazing.

Currently, solder paste has become a key material for microelectronic chip mounting in the computer, radar, and audio equipment industries. As electronic devices evolve towards miniaturization, lightweight design, and high reliability, the size of solder joints is getting smaller, but the mechanical and electrical loads on them are increasing. The issue of residue cleaning after soldering has attracted the attention of many experts around the world.

A method for the preparation of copper solder paste that is automated and scalable.

Compared with traditional copper alloy welding wires, welding rings, and welding strips, the combination of copper solder paste and automatic dispensing equipment can automatically coat complex and irregular parts. The coated parts to be welded then enter a continuous brazing furnace for brazing, achieving continuity and automation of the entire welding process.

A high-efficiency dust-free thin film coating agent device

Soldering flux refers to the flux used in brazing. The function of the soldering flux is to remove oxides from the surfaces of the base material and filler metal, protect the base material and filler metal, reduce oxidation during the heating process, improve the wettability of the filler metal to the base material, and effectively dissolve or break down the oxide film on the surfaces of the workpiece and filler metal.

A more environmentally friendly and energy-saving soldering agent spraying device

Currently, there are basically two types of flux spraying before brazing: spraying and powder spraying. The overall structure of powder spraying generally adopts a hanging spraying method, which means that the workpiece to be sprayed is suspended at the spray gun's outlet. The flux powder is adsorbed onto the spray gun through an electrostatic powder suction device, and then sprayed through the spray gun.
