Generally, leakage of electricity is a topic that many people are most concerned about. This issue is rather complex and is related to many factors. To accurately identify the cause,Solder wireWhen leakage is detected, how can we determine it? JJY solder Paste Manufacturer will explain it to you:

The first thing to consider is notPCBThe leakage caused by the residues on the board, so it is necessary to first determine whether it is correct during and after solderingPCBThe board is cleaned. If there is leakage of electricity after cleaning, there are also several factors that can cause this situation.1.PCBThe board is broken. It has already short-circuited itself. Regarding this,PCBThe pre-welding test can be conducted before the board is used.2.It wasn't cleaned thoroughly. In addition, it is also necessary to clarify whether the cleaning agent used will cause corrosion or leave residues.

PCBThe distance between the solder joints of the board should not be too close, and the frequency of power supply between the solder joints is also a factor that needs to be considered for leakage. If the solder joints are closely clustered or the current frequency between the solder joints is very high, it is best to use lead-free solder wire or rosin core solder wire in such cases(It should be cleaned after soldering).

Leakage may also be related to one's own insulation resistance. The smaller the insulation resistance, the higher the probability of leakage. The insulation resistance of different types of fluxes varies, and what determines this insulation resistance is the active agent in the flux.

This is some information about leakage that I have shared with you all. Please pay more attention to this aspect. For safety reasons, JJY solder Paste Manufacturer recommends that you choose high-quality and active flux, which will also make you feel at ease when using it.
