PCB Soldering Process For Your Printed Circuit Board

Are you looking to know all about the printed circuit board irons? Are you searching for the steps for the printed circuit boards? Today, we are going to discuss all about PCB soldering. Even though, here we are going to discuss all about the PCB soldering process. The above blog is very much beneficial for all such people, who are having background within PCB soldering. So, without wasting your time, you must have a look at the information below:

Things that we will discuss in our post:

What is PCB Soldering?

Before understanding the PCB soldering process, you must have an idea about the PCB soldering. It is the thing, which is all given to the process, which is all used for soldering electrical circuit boards. It is the major technique that is used during maintenance of the electrical circuits and electronics. It is the method, which involves joining of two small pieces of soldering along with the surface of the PCB or printed circuit board. PCB soldering is the way, which is all used for making connections among two electrical components along with the solder Board. 

The things that you require during the process of PCB soldering is soldering iron, solder, and the material that you want to connect along with each other. The biggest thing that you should keep in your mind, while doing the process is that soldering iron is extremely hot and it all works like a pen. So, you must pay attention to it while working.

The other thing that you must understand that there are different types of solder available which are brass, silver, and other and the melting point of such solder is quite low.

Different Soldering Techniques

After understanding all about the PCB soldering you must have an idea about the different soldering techniques. In the traditional time, the wave process is used for the process of PCB soldering. It is the process, which is all used for thru-hole parts, and it is also used for the surface mount parts. The solder is all made along with the combination of all the major things, which includes tin, lead, and many more. 

Soft Soldering

The process of soft soldering is all used for making the connection along with the larger PCB on the small components. The small components are all designed to have the low temperature on the soldering circuits boards, which all offers higher temperature on the heat source. 

Hard Soldering

Hard soldering is the process which is all done during the usage of the two different metal elements. It is all done, throughout the holes of the solder boards. The two processes, which are involved in hard soldering are brazing and soldering. Hard soldering is the process, which all involves usage of the silver, alloy, cadmium-silver, and other things.

PCB Soldering Process for your Printed Circuit Board

Now, coming to our main topic about the PCB soldering process, which is used on the printed circuit board. Before understanding the topic, you must know the equipment which you require during the smt solder. Here is the list of the equipment that you must require are:

Soldering Iron: Soldering iron is an instrument which is used to provide heat to melt the solder. It is all designed in the shape of a pencil. 

Solder Flux: The solder flux work as a purifying agent. It is all used for overcoming three purposes, which are all done to fulfill this job. It is very much important in overcoming the whole project from rust and makes it look clean. 

Soldering Paste: The soldering paste is all available in grey color and it work as a putty. It is the material which is all join the lead along with the chip.

The PCB or Soldering PCB Board

The PCB is the circuit board. It is all surface of the board where all the soldering tools are used to make a connection along with the various components. 

Steps for the PCB Soldering Circuit

Prepare Your Iron

Before moving to the topic, you should prepare your iron first and this process is known as tinning. In this process, coating tip is done on the iron to perform the heat process. You have to first warm iron first and let it cool down. After getting it cool down, you must coat the tip with the help of the solder. While you are doing so, you must need a huge amount of solder. Once you found that you have an excess of solder, then you need to clean that along with the help of the clean cloth. It will help you in getting rid of the excessive flux residue.

Prepare Surface

It is the first and the most important thing that you should consider is to prepare your surface, while cleaning it. A well-cleaned surface is all set for a soldering circuit. You can use a cleaning pad to make it clear from any debris or even from dust. You can also use acetone cleaner to make your surface well-cleaned.

Check the components

Check the components While you are working on the solder boards, you must focus on the smd components soldering. You must have one or two components along with each other while you are working. To start working on it, you must work on the smaller pieces after that you have to work on the bigger one. This technique will help you in balancing. You need smaller components and then work on placing them on board.       

Apply some heat

You can use smd solder, to apply heat on the tip of the iron. This isn’t the weld that will hold the parts set up however is fairly expected to lead the heat from the iron to the board. 

To appropriately warm the joint, hold the iron so the tip contacts both the board and the part lead. This situating is basic since if the tip is in touch with just one of these pieces, the patch will not stick. When the tip is in position, the patch you applied before will connect with both the lead and the board, warming them up and setting them up for the fastening. Stand firm on the iron in footing for a couple of seconds before eliminating it.

It’s feasible to overheat during this stage, which you’ll need to stay away from. In the event that you notice the region beginning to bubble, eliminate the hotness right away. Sit tight for it to cool and afterward heat it once more, more circumspectly this time.

Use solders to make joints

Once you have heated your joints, you are now getting your solder work done. You can easily do so, with the help of the strand of solder, that you have connected along with the solder pad and lead. If you have heated your solder correctly, then you will make the heat to get easily flow inside the soldering circuit boards.  

Continue to add bind around this joint until it’s altogether covered, framing a little hill. At the point when you’ve arrived at this point, quit adding bind and eliminate your iron from the space, saving it. 

As the joint cools, ensure it stays still. If you jar it or permit it to move, the completion will look dull and grainy.


Now, you have done with the process of cool and now it is the last step for the prototype board soldering. During this step, if you found that your solder joint is looking great, then you can move ahead with the next step of trimming. You can finish this work while doing the side cutters from the top of the joint. After doing this process, you move to the next step of placing your solder in a right place.

Whenever you’re done with all your fastening for your present meeting, make a point to tidy up any additional motion from the load up, leaving you with a spotless and completed item.


At last, we hope that you have cleared all the most important steps which are very much important during the PCB Soldering Process.
