Concerned about environmental impact? Laser soldering is here to address these issues

Manufacturers of electronic products have always tried to provide superior and better products. They know that today the consumers have become more demanding and conscious because of increasing competition and options in the market. Also, they have become more alert towards any harmful impact on the environment. This is the reason that manufacturers try to remove lead from solders. This ultimately gave birth to lead free solder that melt at higher temperature. But there are some issues attached with this new found lead free soldering. They do not connect or flow as well as the traditional ones. 

Laser soldering is a new technique that is directly applied at the joint. It has many advantages as it is very quick and hassle-free. Solder wires and solder sticks are used widely for joining metals. Solder wires are used by heating but with laser soldering, these are not heated and completed in few seconds. Another laser type that is famous is diode laser as these are compact, energy efficient and require lower maintenance. So, why would a manufacturer stay away from such a wonderful technique?

Here is brief description of the process of soldering that will act as a guide for the beginners:

1. Clean the surface of the metal so that it is completely free from rust or any sort of coating
2. Now you need to apply the tinning compound or flux, depending on whether the solder is lead free or not
3. Clean the tinned area with a piece of cloth
4. Now apply the solder. Here, the solder bar will touch the tinned surface 
5.  You need to prevent the soft solder from getting stuck with the paddle by heating it gently
6.  Refine the shape by using a flat flexible file  
7.  Use baking soda to clean the surface area so that any residual acid is neutralized from flux operation

There are certain pointers also to recognize whether a panel needs to be soldered or not. You need to avoid soldering of perforated panels and partially welded seams. You need to keep updated so that any important latest techniques are not missed.
