Several Simple Methods to Remove Solder

Extra solder filling a hole happens quite frequently. There are several useful and simple methods for removing solder from a PCB hole. Usually, the clog is residual solder that occurs when an existing electronic component is desoldered and removed.


Drill

One of the effective methods is to use a small hand drill or a pin vise with a miniature drill bit.

For many PCB layout programs, the hole size is default. People can easily with a certain size of drill. But do not use an oversize drill to remove the solder because it will do harm to the through-hole plating that connects the trace from one layer of the board to another layer. The loss of electrical connectivity may prevent the circuit from working.

Desoldering Braid

On the other hand, there are people that remove solder by desoldering braid. Desoldering braid is made from tiny woven copper wires that wick up adjacent solder when heated.

The idea is that you place fresh desoldering braid on anywhere with excess solder, and then apply heat to the braid using the tip of the soldering iron. When the braid is saturated with old solder, you simply take off the solder.

Just Leave Solder in the Hole

Just do nothing if there is only one hole is clogged of each component. When you are going to solder the component, it is acceptable to simply heat the component lead and the solder will melt.
