Detailed introduction

In brazing, the solder resist can prevent the molten solder from flowing to the position where the solder resist is applied. Therefore, it can avoid the contamination of the surface of the parts to be welded due to the spread of the solder, and it can also prevent welding at the locations where welding is not required. . For example, copper brazing filler metal has very good fluidity on the surface of carbon steel, and it is easy to form a large area of diffuse flow, which leads to irregular and unsightly red (copper) areas on the surface of the weldment. For another example, in brazing in a furnace, it is often necessary to tighten or clamp a part to be welded with a mold. At this time, special care must be taken not to weld the mold to the workpiece.

In brazing, most of the solder resist is used in the context of brazing in a furnace (no soldering aid required ). There are mainly three kinds of base materials used in conjunction with the solder resist produced by Yantai Guguang Brazing Material Co., Ltd. First, ferrous metal, namely steel and stainless steel; second, aluminum alloy; third, highly active metal, namely titanium or zirconium alloy. The welding temperature mainly has three ranges: one, about 600 degrees Celsius (used for brazing aluminum alloys); two, about 800 degrees Celsius (usually used for brazing highly active alloys); and three, 1,000-1300 degrees Celsius (usually used for brazing ferrous metals).

The main components of the solder resist for brazing are basic oxides, activators, adhesives, and solvents. There are three main types of solder resists produced by Guguang Company for different scenarios: water-based, fast-drying, and slow-drying, with the most water-based applications.

The application of solder resist is a relatively complicated and time-consuming process. Many companies try to avoid using solder resist. However, in practice, the use of solder resist is sometimes unavoidable. To improve the efficiency of the use of solder resist, Gakuen provides a variety of coating processes for solder resist. First, brush coating, which is the most common and easiest method; second, spray coating, which is more efficient, but the coating is not accurate; third, pen coating, which is less efficient, but the most accurate coating; fourth, dipping, The most efficient, but the accuracy is very low.
