​Tin line, and more with rosin, help flux under the condition of surface tension is big, a little slit can be separated. No tin with absorption with multi-strand wire, not as thin as possible, multi-purpose flux increase liquidity solder. In fact, sometimes afraid of earthquakes a fall after adequate heating is all gone.

Around a circle to manage socket, bad soldering iron, tin tin old not net absorption, absorption and are double row needle, some even slightly on the through hole, just how do down behind the brute force method, from the front with iron socket pin plastic hot enter a pair of tweezers to pull out of a root, busy for a night, plastic seat.

Find a power point of the soldering iron, put plenty of solder on the head, back and forth in this row needles on the solder joints of walk, walk a few times, in the process, on the other hand, try on the other side pull row needles. Pay attention to the unnecessary time is too long, long will get solder joints.

General circuit board the tin with vacuum suction tin tin or line with woven, more troublesome. To general circuit board using more simple solution: use common soldering iron, welding head clean eating live solder.

Welding head iron on the vertical upward, hold circuit board, will need to remove the solder welding, solder will depend on gravity flow to the soldering iron head. Tin welding head to eat full jilt a clear again.

The way to remove the very clean, even the welding holes can be exposed. You might as well try, the disadvantage is that the neck more laborious!

Actually everybody worry burns is too cautious, with a little note can be avoided. Soldering iron tilt a bit, for example, not hot, on the workbench wouldn't ironing the clothes, pay attention to other people during soldering iron rejection is being too close to you.
