No-clean solder paste is a new type of solder paste that emerged with the development of the electronics industry and the need for environmental protection. It is addressing the issue of non-useCFCCleaning solvents are of great significance in reducing environmental pollution and addressing the compatibility issues between fine gaps and cleaning agents caused by the assembly of high-density components. Now, let's talk about it from the solder paste manufacturer:

from90Since the early 2000s, no-clean solder paste has been widely used in the electronic industry for soldering electronic components and printed circuit boards. With the continuous expansion of the application scope of high-density, lightweight, miniaturized and high-performance electronic products, the application environment is becoming increasingly complex, and the reliability requirements for products are also getting higher and higher. Therefore, higher requirements have been put forward for no-clean solder paste.

For use as a no-clean productFlux pasteThe following several conditions must be met:

1The residue after welding is the least.

2Under normal temperature and humidity conditions, the residues left after welding remain inert and will not cause corrosive effects.

3After welding, the residual substances should have a relatively high insulation resistance value.
