I believe all the partners should understand that sometimes the solder paste does not attach solder because of insufficient activity. In that case, does it mean that the higher the activity of the solder paste, the better?Next, byJJYSolder paste manufacturerAnalyze for the partners:

    Solder pasteThe activity level of tin is closely related to the total amount of active agents added. Generally, tin with poor actual tinning effect is because its activity is too low. Perhaps some people would say, "Then just add more active agents, wouldn't that be fine? In that case, Shangxi is definitely good." In fact, this is incorrect.

    Active agents have a relatively corrosive and irritating effect. If too much active agent is added to the solder paste, although the expected effect of tin application during packaging printing will be better, it is not beneficial to allPCBThe 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 necessarily the higher the better; an appropriate level is sufficient.Shenzhen JJY Industrial Technology Co., LTDIt is a company that has been engaged in the research of solder paste and solder wire for more than ten years.Solder wireManufacturers of solder paste and wire for lead-free solder paste, leaded solder paste, solder rods, leaded solder paste, etc.
