Abstract

The invention relates to a low-temperature catalyst hot air module. The low-temperature catalyst hot air module comprises a module outer box body, wherein a module inner box body is arranged in the module outer box body, a hot air pore plate is arranged at the bottom of the module outer box body, a catalyst module is arranged in the module inner box body, and a heating wire module is arranged at the top in the module inner box body. Compared with the prior art, the low-temperature catalyst hot air module has the advantages of being material-saving, compact in structure and energy-saving.

Description

technical field [0001] The invention relates to the technical field of reflow soldering, in particular to a low-temperature catalyst hot air module. Background technique [0002] As we all know, in SMT (Surface Mounting Technology) production, various electrical components are combined with the PCB board through the melting and solidification of solder paste. Solder paste is a paste made of fat-like flux and powder solder, which is applied to the soldering part of the PCB board by printing. After mounting the required electronic components, it is heated and melted in a reflow oven for soldering. The flux in solder paste is an important auxiliary material in the SMT soldering process, and most of the active fluxes based on rosin are currently used. Common flux components also include activators, film-forming substances, additives, and solvents. The state of solder paste in each stage of reflow soldering is constantly changing: in the preheating stage, part of the solvent in...
