What is liquid tin and how to use it correctly

Passion for electronics is a truly fascinating process, thanks to which it is possible to create various electronic devices on our own.

When creating the next electronic gadget, the tinning procedure for the prepared board is almost mandatory.

In order to speed up this boring and time-consuming process, liquid tin was created. Didn't know about him? Then I'll tell you everything in detail.

The composition of liquid tin and the subtleties of its application

Taking a bottle of liquid in your hands, you can see that its composition is as follows:

First remark. Take into account such a moment that a normal liquid tin solution should have no sediment at all or the sediment should be present in a minimum amount.

If you open specialized forums, then you can read a lot of controversial reviews about liquid tin. Of course, a lot depends on the quality of the solution used, but more than half of the failed experiments on chemical tinning are associated with improper board preparation.

How to properly prepare the board

So, suppose you have already etched the board and now want to tin it with liquid tin.

The first thing to remember: in no case should the board be processed with sandpaper.

In order to prepare the board, take a solid and liquid detergent, connect them together so that you get a gruel and rub the surface of the board with your fingers.

The next step is to degrease the workpiece. To do this, we treat the surface with acetone, and then be sure to clean the board with alcohol.

We cover the board with liquid tin

Further, without touching the cleaned surface, we place the board in a container with pre-poured liquid tin so that there is at least 1 cm of liquid above the surface.

You will see the result almost instantly, but to fix the effect, you should keep the board in the solution for at least 10 minutes and only then can you pull it out.

If you do not plan to solder immediately, then put the processed board in a tight plastic bag, and after long-term storage, remove the board again, treat it with alcohol and put the board in a solution of liquid tin (fortunately, it can be used repeatedly until it is completely depleted) for a couple minutes.

Thus, soldering will be carried out easily.

Conclusion

Whether or not to use liquid tin in their electronic homemade products is up to everyone for himself. The main condition is to strictly follow the technology and there will be no problems.
