A Comprehensive Guide on Lead-Free Soldering Materials and Process

Almost every electronic item needs a solder in its production. Solder acts as a glue that attaches the parts of the electronic items to a circuit board. This is why the choice of solder can play a huge role in the soldering process. If you do not pick the right type of solder then the soldering process can be extremely dangerous. Lead-free solders are becoming popular these days because of the many benefits it has to offer. Although a lot of people go for Amtech lead free soldering materials, the lead-free soldering materials of Shenzen green Qiantian Tin Technology are equally the best.

What is a Lead-Free Solder?

It is common knowledge that lead can be extremely hazardous. This is why the electronic industry has restricted the use of lead in the manufacturing of consumer electronic parts. Therefore, lead-free solders have become the standard solders in the market these days. While the traditional solders used in the industry were a mixture of lead and tin, leaf-free solders have completely omitted lead from their manufacturing process. Some of the best lead-free manufacturers out there are Amtech lead free soldering materials and Shenzen green Qiantian Tin Technology.

What Is The Difference Between Lead-Free Solders and Leaded Solders?

Lead-free solders are gaining popularity all over the world these days. That’s because they offer many health and environmental advantages to both the manufacturers and the users. This is why almost every industry is using lead-free soldering materials. There are several varieties of lead-free solders available in the market. The most common is the one that contains 0.7% copper and 99.3% tin. On the other hand, the composition of the leaded solder is based upon 40% tin and 60% lead. These two materials are blended on the melting point that ranges between 170 to 190° C.

If you look at lead-free solders and leaded solders performance-wise, they both work slightly different from each other. The major difference between the two solders is their melting point and the wetting process. Lead-free solders have a higher melting point as compared to leaded solders. On the other hand, the wetting process is slower in lead-free solders.

Some Lead-Free Soldering Materials

Before lead-free solders became standard solders among leading manufacturers such as Shenzen green Qiantian Technology and Amtech lead free soldering materials, leaded solders were the most common solders used. All the electronic items were designed in such a way that they were able to withstand the use of lead solders in their manufacturing process. But, the introduction of lead-free solders has revolutionized the way solders are used. This is why their use has become so popular among all the materials. Some common materials used for lead-free soldering are given out below.

• Tin
• Antimony
• Copper
• Zinc
• Silver
• Indium
• Bismuth

Why Are the Manufacturing Companies Using Lead-Free Solders?

Nowadays, many leading manufacturing companies are producing lead-free solders. The major example of this is Amtech lead free soldering materials and Shenzen green Qiantian Tin Technology soldering materials. That’s because they are better in comparison to leaded soldering materials.

Furthermore, the electronic industry guidelines also compel the manufacturing companies to use lead-free soldering materials instead of leaded materials. Based on the regulations of the electronic industry, the manufacturers that do not comply with the rules of producing lead-free soldering materials will not be allowed to do business anymore. This is why almost all manufacturing companies are using lead-free solders in their manufacturing process.

What Are the Advantages of the Lead-Free Soldering Process?

The lead-free soldering process offers several advantages to both the manufacturers and the users over the leaded soldering process. This is why Amtech lead free soldering materials and Shenzen green Qiantian Tin Technology soldering materials are so popular out there. Let’s check out some of these advantages below.

1.     Protection of the Environment

Lead-free solders are extremely important to protect the environment. That’s because the lead materials that we use can find their way to the ground and stay there for a long time. What’s more, the lead that is present in the fuel can bring air pollution in urban areas. The lead can affect marine life as well if it comes in contact with lakes and seas. The people that drink lead-contaminated water can fall sick as well. Lead can be hazardous for pregnant women too. This is why it is recommended to use lead-free soldering materials instead of lead soldering materials.

2.     Better PCB Soldering

Another reason that the manufacturers are using lead-free solders over leaded solders is that they provide better soldering of PCB. That’s because lead-free solders will never spread during the reflow process. This is why the manufacturers will get better results during PCB soldering with lead-free solders.  What’s more, the lead-free soldering process does not arise with any other significant issue as well. On the other hand, the manufacturers that use leaded solders will more likely face the problem of voids and fillet lifting. Thus, you will get the perfect PCB solders with lead-free soldering. This is why leading manufacturers are using lead-free solders such as Amtech lead free soldering materials and Shenzen green Qiantian Tin Technology soldering materials.

3.     Easier Oxidization with Chemical Compounds

As compared to leaded solders, lead-free solders require a higher melting point. Their melting point is 34°C higher than that of traditional lead solders. As a result, it becomes extremely easy for the lead-free solders to oxidize with chemical compounds. The chemical compounds can grow extremely quickly between metals. This is why their quick oxidization is very important. On the other hand, leaded solders have a lower melting point. This is why they are not able to oxidize quickly.

Final Thoughts

Lead-free solders offer several advantages to both the manufacturers and the users. They are not only safe to use but they offer better PCB soldering as well. This is why their use has become so popular and they are used with a wide range of materials.
