What Is The Difference Between Soldering and Desoldering?

When working in manufacturing processes involving metals, it is often very important that one knows the difference between soldering and desoldering. While soldering involves the process of joining pieces together by establishing a joint, desoldering is the opposite process where the solder is removed from a joint. Both processes can be very important for a number of applications and needs, and they both involve separate sets of equipment and safety instructions. Additionally, the practice of soldering and desoldering can be tricky to master, and both practices are known for their learning curves. To help you better understand how each is carried out and when, we will briefly discuss soldering and desoldering in this blog.

Soldering is a practice that humans have carried out for thousands of years, and it has seen various advancements leading into the present as new technology and methods arise. In general, soldering consists of joining two or more pieces together through the application of heat to melt a solder or filler metal that is placed in the joint. Generally, this metal exhibits a lower melting point than the joining parts for the benefit of creating a strong joint. Soldering should not be confused with welding, and soldering does not require the melting of the work pieces to create a secure attachment.

When conducting soldering processes, it is important to have equipment such as a soldering station, soldering iron, soldering gun, and various tools and accessories that are chosen based on the application. A soldering station will often come alongside essential tools to get started, and they will require a connection to an electrical outlet so that tools can get the power needed to create high temperatures. The soldering iron is one of the most basic tools that allows for many operations to be carried out, and they come in the form of a pen where the tip can be heated to melt a solder. The soldering gun, meanwhile, can be a little more advanced in its capabilities, and it has the shape of a pistol where heating is activated by pulling the trigger of the tool.

Regarding desoldering, the practice is typically carried out when there is a need for a component change or repair for the soldered assembly in question. To remove the solder from a connection, heat and a vacuum, wick, and braid will be required. There are various desoldering practices that one may carry out, though the most common is simply to remove one component at a time. As desoldering requires the melting of the solder to remove the joint, it is important to have clean tools and to regularly remove any excess solder on the piece in question.

Like how a soldering station is the perfect place for soldering, a desoldering station is extremely useful for conducting component swaps and repairs. In order to avoid accidentally causing damage to any components as you desolder them, it is important to use the correct size nozzle for heat application. This is because too much or too little heat can quickly cause issues and break down parts. With the correct toolsets and practice, desoldering can be a fairly straightforward process.
