What is halogen-free solder paste? What are the characteristics?

Everyone should know that halogen-free solder paste is a product specially designed forSMTThe halogen-free, lead-free and no-clean solder paste designed and manufactured must passSGSInternational general standard certification is required so that the survival workshop can be put into use. Currently, the European Union has relevant regulations that most electronic products must be halogen-free. With the development of electronic technology,SMTThe solder paste applied is also developing rapidly. Lead-free, halogen-free and no-rinse solder paste are all manifestations of technological improvement. Now, let's have the solder paste manufacturer explain what the general features are:

Characteristics of halogen-free solder paste:

No residue of halogen compounds; Excellent printability, eliminating omissions during the printing process; It has good solderability and appropriate wettability on all types of components. During reflow soldering, very few solder beads are produced, effectively reducing the occurrence of short circuits. After soldering, the solder joints are full and uniform, with high strength and excellent electrical conductivity. Printed inPCBIt can still maintain its viscosity for a long time after the plate is printed, and stable printability can be achieved during continuous printing. Halogen-free solder paste is non-toxic and free of halogen. It has strong wetting performance, good moisture retention performance and can be printed continuously12More than one hour; Good welding performance and strong weldability; There is little rosin residue, and the residue is white and transparent.

From an environmental perspective, as halogen elements can have adverse effects on the nervous and reproductive systems of the human body, the electronics industry, especially in the import and export of electronics, is increasingly demanding halogen-free solder pastes. As a result, halogen-free solder pastes are becoming more and more popular, while the use of halogen-containing solder pastes is decreasing.

In terms of price, Halogen-free solder paste is more expensive than halogenated solder paste, but halogen-free solder paste is more environmentally friendly and requires almost no cleaning.
