When partners are using Low-temperature tin wire, they often find that there is a problem of excessive Flux splashing. So, what causes the flux splashing? Next, let Shenzhen JJY answer some questions for our partners.

Too much flux is used. During the soldering process, the flux melts first when heated. When it expands, the tin on the surface has not yet melted, which builds up the expansion force of the flux. When the tin on the surface finally melts, the flux inside bursts out, causing splashing. The solution is to reduce the Flux Content while keeping the soldering speed feasible.

A rather crucial point is whether the customer uses intermittent or continuous soldering. The intermittent soldering method can reduce the flux. For the continuous soldering method, the rosin content should be higher; otherwise, it will affect the soldering. You can moderately control the heat of the soldering iron. It is better to use a constant-temperature soldering iron.

It is related to the formulation inside the flux. In the production process, the flux inside the Tin wire contains gas or moisture. When burning rosin, the temperature control and burning time should be long enough to allow the moisture of the rosin and the surfactant to evaporate completely.

When the tin wire used contains a relatively high tin content, a soldering iron with lower power can be used. This can reduce the occurrence of flux splashing. Multicore Solder Wire can also be selected. This can disperse the expansion force of the flux when heated and reduce splashing.

Changing the properties of rosin and increasing its viscosity can cause some inconveniences and is generally not advisable. If you want to know more about low-temperature tin wire, welcome to consult Shenzhen JJY. Let's learn and grow together!
