How to Desolder: 3 Mistakes to Avoid

People who are into metal working projects and electronic/electrical projects need to know how to desolder. Desoldering is the process of removing unwanted, wrongly placed, or excess soldering on a piece of equipment or connection. The process involves the use of a desoldering tool as well as a soldering tool. There are two types, but they pretty much do the same thing. These two tools are the soldering sucker and the soldering wick. The soldering sucker uses a suction mechanism that sorts of vacuums the heated solder. The solder wick is a special braid that removes the solder by sticking to it. There are some things to consider when learning how to desolder. Read on for more information.

1 - Desoldering Without Proper Planning and Preparation

Desoldering cannot be done just at anytime that one feels like it. There are proper times for desoldering. One instance is when the connection created by the solder is not strong enough to hold the joint firmly. Since the joint may loosen after a period of time, it is recommended that the solder be removed and replaced with a stronger connection.

When working with a circuit board, make sure not to solder and desolder frequently, especially on a single connection, because it may destroy the components being connected or the circuit board itself. It is best to take careful preparations when soldering, in order not to constantly be desoldering. Desolder only if the component is soldered at the wrong place. Just be sure to solder the component at the right location the second time to avoid risk of damage to the component and the board.

2 - Lack of Knowledge and Improper Use of Desoldering Tool

When considering how to desolder, also consider what type of desoldering tool to use. The desoldering device that is typically used is the desoldering suction or pump. When using this tool, be careful not to move the hand at the instant the suction is released because it may only suck a portion if not properly positioned. Be sure to clean the tool first before using it in order to ensure maximum performance. Since the solder residue may clog the device, always inspect for any sign of clogging.

Another solder remover is the solder wick or braid. This special braid is very useful in removing any remaining solder that the pump did not remove from the joints. Although the braid is indeed effective, it may be quite costly because the used portion cannot be reused again. Another problem with the tools is its tendency to stick to the joint instead of removing the solder on the joint. When using the braid, make sure not to remove it from the joint before the solder cools off and sticks back.

3 - Engaging in a Project Without Ample Practice

When desoldering, be sure to grasp the techniques first before working with delicate materials. Common mistakes can be avoided by mastering soldering and desoldering skills. Before heading on to more difficult soldering and desoldering tasks, practice on easier tasks first until they are mastered.
