What is the influence of small particles on the activity strength of solder paste? Let's identify it together with JJY solder Paste Manufacturer

Some friends, do you think that "the smaller the particle size of solder paste, the stronger its vitality"? Is this indeed the objective fact? JJYSolder paste manufacturerLead your partners to learn about it carefully together.

Relatively speaking, it has just been masteredSolder pastePeople who have not been in the field for long, or perhapsLead-free solder pasteSome people might agree that this view is correct. Only after learning can you discover an incorrect view at that time. JJY solder paste Manufacturer would like to explain why smaller solder paste particle size does not necessarily mean stronger vitality?

In fact, the reason lies inCarry out footworkICWhen printing the packagingThis is why the partners have such a view that the solder coating rate of solder paste with larger particle size is even worse than that of smaller particle size. The main reason is that many positions have not been coated with solder or have not been coated with solder at all. This is why some people feel that it is caused by the lack of vitality of the solder paste.

The objective fact is not like that, because of the secrecyICThe intervals between electronic devices are very small. Only very tiny fine particles of solder paste can penetrate sufficiently, while larger particles are blocked and cannot penetrate at all. However, the strength of their vitality needs no further elaboration.

In conclusion, if the small particles in the solder paste do not cause solder crawling or show weak tensile properties, it may be related to the weak vitality of the solder paste.

The activity of solder paste is related to the activator added. The stronger the activity of the surfactant, the stronger its vitality will be. Of course, the vitality of the solder paste should be appropriate.
