It is a common phenomenon in manual welding that solder wire does not stick to solder during soldering. Recently, many customers have askedSolder wireWhat is the reason for not sticking to tin? The following is a summary by JJY Tin Wire Manufacturer:

1The surface of solder wire is generally coated with a layer of anti-sticking coating, which is used to prevent the solder wire from sticking to soldering tools such as soldering irons. This coating can effectively reduce the adhesion of tin, making it less likely for the solder wire to stick to the tin.

2The cleanliness of the solder wire is also one of the factors affecting its adhesion. If there is dust, grease or other impurities on the surface of the solder wire, or if the temperature of the soldering iron tip is not high enough or the heating time is not long enough, it will affect the adhesion between the solder wire and the tin.

3The adhesion between the solder wire and the tin is related to the temperature of the soldering iron tip. If the temperature of the soldering iron tip is too low, the solder wire cannot be fully melted and thus cannot fully fuse with the tin, making it difficult to adhere to the tin.

4The reason why the solder wire does not stick to tin may also be related to the quality of the tin. If the quality of the tin used is poor or other impurities are mixed in the tin, it will affect the adhesion between the solder wire and the tin.

The above are some situations that may occur when the soldering iron tip does not stick to tin during wire soldering. You can have a look. If you don't understand, your partners are welcome to consult Shenzhen JJY Industrial Technology Co., LTD. Let's learn and grow together!
