If you are a soldering hobbyist or a professional, one piece of equipment you might want to consider investing in is a desoldering station. There are quite a few options to choose from that provide flexibility for the user. However, one thing you will need to decide on is the method that you want to use to desolder or rework your PCBs. There are desoldering stations and hot air rework stations. Both accomplish relatively the same thing, but work in slightly different ways.
Hot air rework stations work better for small jobs when you are working with older PCBs. It is not exactly precise, but gets the job done by melting old solder so you can remove components. In addition, hot air rework stations are much faster to use as you can usually melt a part off and reapply a new component within a short span of time.
Hot air guns are also non-contact options, which can prevent damage to your PCB. Another benefit of hot air rework stations is that many times they also double as solder stations.
With desoldering stations, you get a more precise execution. Most include vacuum pumps for removing old solder and maintaining precise control. Desoldering stations are much easier to manage and clean up from since they limit the area of rework compared to hot air gun stations.
Unfortunately, one downside of desoldering stations is that there is a risk of voltage damage when using due to the contact options. However, these stations tend to be much more cost effective compared to hot air rework stations.

PCB Tool ExpertConclusion
We have provided a complete list of various hot air rework and desoldering stations. This was to provide a comparison between the two as both work well for desoldering projects. However, hot air guns are more broad based solder removal units, while desoldering guns provide more precise melting.
It really all depends on what type of work you will be doing. Desoldering guns are definitely more precise, but can do pinpoint damage to the PCB if not used correctly. However, hot air guns do not include vacuum pumps for solder removal so they do not always remove all the solder in the first go around.
The different models we have discussed here come with a variety of extra options, but most include digital displays along with built-in safety features. These safety features include things like sleep mode or automatic shut-off during idle periods.
Most of the units also include docking stations for placing the units during cool down or when not in use. Of all the products, the Aoyue 2703+ had the most features and includes a soldering iron, a desoldering gun, and a hot air gun, which provides a lot of flexibility to the user.
As always, we recommend reading over the individual reviews on these models and any other units you might be interested in to get good user feedback before purchasing.
