What kind of lead-free solder paste is suitable for fine-pin IC electronic components? Let's briefly discuss.

If you are a familySMTSurface mount manufacturers, in soldering and printing denseICWhen dealing with electronic components, some situations are usually encountered, such as problems like solder leakage and holes. Why is that? It might be that the lead-free solder paste you chose is not applicable. So what kind?Lead-free solder pasteIt is suitable for thick feetICWhat about the use of electronic components? The following solder paste manufacturer will briefly discuss:

First of all, we all need to fully understand what a "secret foot" isICElectronic components. "密脚" 可 以 翻 译 为 "tight feet"ICAs the name suggests, it means that the feet of the pointer are relatively denseICElectronic components have small gaps between each other. If you want to densify theseICFor different pins of electronic components to be soldered skillfully, the lead-free solder paste used must have good activity. Only solder paste with very good activity has good solder climbing ability. At the same time, it is stipulated that the solder paste should be granulated to a smaller size. Only smaller particles can be used for the tiny pin gaps. If the particles are too large and get blocked by the pins, it will naturally lead to missed soldering.

Therefore, weld the tight feetICWhen choosing electronic components, lead-free solder paste with good activity and small granulation should be selected. Only this lead-free solder paste can be used for the solesICCircuit soldering brings better results.
