The main purpose of using flux is to remove the unwanted residue while soldering. The initial process is when you heat the tin to the liquid to make proper solder. In the desoldering process, you also melt tin to remove it. To be sure that after desoldering the area you work on is clear you should use flux. There are different types of fluxes. It is recommended to use those who are compatible with your target of soldering.

Tip: You only need to heat gun the board for a few seconds, or else you will melt the copper plating on the PCB and damage the board, as shown in the picture. The Ultimate Guide to Desoldering Stations What’s the Difference Between Hot-Air Rework and Desoldering Stations? You can consider other SMD soldering and desoldering station options according to your requirements and budget. We have chosen all equipment based on ease of use, Suction Power of vacuum unit, type of soldering station, Temperature Setting, Warranty period, and no of Accessories delivered. Desoldering Stations Comparison Table

Some of the key features include this product that it has 2 has two lines, one for power and another for vacuum directed to the station. It consists of a transparent display to set input and other crucial settings. Zhongli SMD soldering and desoldering station temperature can be done by up and down the adjustment buttons. This system is specially designed for lead-free soldering. What I Like/Dislike about Zhongli:

I can describe this desoldering heat gun as the best thermal performance available in the marketplace. It’s a futuristic innovation with well-designed features. The Hakko FR301 Safe Portable Desoldering Tool features a Unique pump design that helps lower vibration and noise. But it feels smooth, confident, and satisfying without lowering the vacuum pressure and flow. I used his best desoldering stations, and I never faced using them. Key Features: The memory temperature function saves you some time in setting up the required temperature every time you turn on the desoldering station. When you turn on the station, it will heat up to the temperature that you set before turning off the device. Furthermore, the settings get easily switched from Celsius to Fahrenheit (as per your convenience) and its dedicated buttons let you tune up/down the temperature level. The pistol grip of the soldering gun is convenient and safe to hold, and controlled via a microprocessor. Single hand operation that can effectively remove solder from one-sided or two-sided soldering equipment. A three-in-one system allows you to vacuum, desolder, and solder. One-year US Warranty can also be considered to buy the best desoldering station. It’s ultimately one of the best soldering desoldering stations on the market, What I Like/Dislike about YIHUA 853D:The bad things about the hot-air rework are, firstly it is very expensive compared to the desoldering station, and secondly, it is heavy and large in size. If you are a person like me, a weak guy, then better do somebody lifting before buying it. Just kidding! This kind of innovative technology puts JBC desoldering products ahead of other competitors on the market. It is an excellent option with a variety of Multiple features. Desoldering stations use heating elements, air pumps, and soldering irons to melt and remove solder wherever you want. Desoldering stations require more power, and sometimes there is a risk of voltage leak damage involved.
