How to use soldering iron tip resurrection paste and what precautions should be taken
The soldering iron tip is oxidized after a short period of use. The oxidized tip is inconvenient for soldering components and has to be replaced. Now, with the soldering tip resurrection paste, it is simple and economical, and the soldering tip can be reborn. Effectively removes the oxide layer from the welding tip. And re-tinning the welding tip to achieve the purpose of regeneration of the welding tip. It can resurrect various soldering iron tips that have been burnt black due to oxidation.
How to use soldering iron tip resurrection paste:
1. Regeneration operation is performed when the temperature of the welding tip is 300℃~360℃.
2. Let the soldering iron tip and the resurrection paste rub together repeatedly and wait for a few seconds.
3. Use soldering sponge or copper wire to clean the soldering tip.
4. Plating a new tin layer, the soldering iron tip will be as clean as new.
If the regeneration effect is not obvious after one operation, repeat the steps 3-4 times until the desired effect is achieved, and then plate a new tin layer.
Precautions
I usually use a soldering iron sponge to wipe the tip of the soldering iron. Because I wipe it too clean, the tin layer will be directly oxidized. This situation can easily lead to the tip of the soldering iron being burned (not being able to apply tin). In this case, even if the temperature is increased, the temperature is not hot enough. To melt tin, follow the above method.
When the soldering tip regeneration abrasive remains on the soldering tip for soldering, the abrasive adheres to the printed circuit board and may corrode the circuit board. Please completely remove the abrasive from the soldering tip before proceeding with soldering.
When the soldering iron tip is burnt black and oxidized and does not stick to tin, do not use a file to file the surface of the soldering iron tip. The alloy layer on the tip of the soldering iron tip is very thin. If you use a file to treat it, it will easily cause the tip to be completely scrapped. With soldering tip repair After applying the paste, you only need to install the used soldering iron tip on the soldering iron, turn on the power and heat it up. After the temperature reaches your usual soldering temperature, dip the soldering iron tip into the repair agent, and then immediately tin the head with tin wire, back and forth. A few times is enough.
Solder paste is suitable for welding of generally smooth surfaces, such as two steel wires with smooth surfaces, wire welding, and is suitable for all external patch welding (note that it must be cleaned). It is not suitable for BGA welding because it has no stickiness!
