CP-15B, CP-20B, and CP-30B Goot Wick Lead-free Sucking Wire with Bulk Length RoHS-Free Desoldering Wicks
The mainboard will leave a lot of soldiers behind during desoldering, which will have an impact on the chip welding. The standard procedure for cleaning tin involves placing the iron tip on the suction wick and moving slowly across the chip pads. This causes the solder to be drawn up by the suction wick.
The best way to clean the chips after this is to use washing water. The suction tin wick can be used to clean the tin of large chip components. With a suction tin, the tin of aluminum electrolytic capacitors can be cleaned.
