A brief discussion on whether higher activity of solder paste is always better?

Recently, many people have been asking, what ifSolder pasteIf you don't apply solder, people will look for the reason to see if the activity of the solder paste is too low. But some people will say that the more activity, the better. Does that mean it's easy to apply solder? What I can tell everyone about this is the denial of food. Why is that? Below, the solder paste manufacturer will explain it to everyone:

Everyone knows that there are many additives in solder paste, among which one is called an active agent. The active agent is the key solvent that determines the activity of the solder paste. The activity level of the solder paste is related to the amount of active agent added. Generally, those with poor tin coating ability The solder paste is because its activity is too low. 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 incorrect.

The reason why solder paste is not coated with tin is that its activity is too low. By adding more active agents when making solder paste, the problem can be solved. But is it better to be more active?The answer is obviously no, because the active agent is a corrosive chemical substance. The active agent content in the solder paste is too high. The effect of tin on the solder paste is relatively good, but the solder paste is printed onPCBUp.PCBThe board will be corroded to a certain extent, which will damage the circuit. In the past, the damage will be reducedPCBThe lifespan of the board will be damaged when it goes badPCBBoard.

From this, it can be seen that the activity of solder paste is not the higher the better, but a moderate level of activity. In addition, the same goes for other additives in solder paste. One should not blindly pursue the effect of adding too much while ignoring the adverse effects of excessive addition.

As mentioned above, everyone should pay more attention during the operation process. Generally, a moderate amount of addition is sufficient. Well, I believe everyone should be quite clear now. If there are any further questions, I also welcome everyone to communicate together!
