I replaced a component on the PCB board with a 40W electric iron,Insert the replacement new components into the PCB board,Use the electric iron to heat the horn of the element and place the solder on the other side of the antenna (from left to right: solder, element, horn, electric iron)At this point, the solder melts and runs to the head of the electric iron and does not remain on the antenna of the elementExcuse me, why is this solved?Is it necessary to have rosin around the tentacles first?I don't know if there is any rosin in my solder wire
Not clean around the tentacles, first clean the tentacles, and then plated with tentacles on the line
Before soldering, it is better to solder each pin to the tin. If you do not hang on the tin, you can first use a knife or sandpaper polished, so that the bright pin, and then rosin hanging tin is much easier. (place the pin on a block of rosin, with tin on the tip of the iron)
With good soldering, good soldering iron, the station rosin can be taken away
