Isn't it true that the higher the activity of solder paste, the better?

Solder pasteIf the solder paste is not applied, everyone will look for the reason to see if its activity is too low. But is it true that the higher the activity, the better? The answer is no. Why? Now, JJY solder Paste Manufacturer will explain it to you:

As is known to all, there are many additives in solder paste, one of which is called active agent. The active agent is the key solvent that determines the activity of solder paste. The activity of solder paste is related to the amount of active agent added. Usually, the poor adsorption capacity of tin is due to its low activity. Perhaps some people would say, "Then just add a little more activator. This way, the solder paste will definitely work well!" In fact, this is wrong.

Active agents have a relatively corrosive and irritating effect. If too much active agent is added to the solder paste, even ifSMTWhen reflow the printed surface mount, tinning is expected to have a better effect, but it is correctPCBThe board has a relatively corrosive and irritating hazard, which can damage the path and thereby reduce itPCBThe service life is not worth it.

Therefore, the activity of solder paste is not the higher the better; rather, a moderate level of activity is better. In addition, the same goes for other additives in solder paste. One should not blindly pursue an effect by adding too much, while ignoring the adverse effects brought by excessive addition.

To sum up, everyone still needs to be quite cautious during the operation process. Generally, a moderate amount of addition is sufficient.
