What is lead-free solder? Is it safe for users?

Lead-free solder is a commonly used material today. So do you know what component lead-free solder is made of? Is the use of lead-free solder safe for users’ health? Follow along with the article below to get these questions answered!

What is lead-free solder?

Lead-free solder is a type of solder with a lead-free composition. Melts at high temperatures from 90 – 450 degrees Celsius are used to bond metal surfaces together. This material is commonly used in electronic and component manufacturing plants.

Lead-free solder is used together with a tin soldering iron to create a polished, beautiful, and durable solder joint over time. Lead-free solder retains the inherent properties of the solder metal. At the same time, it also has good electrical conductivity, and at any temperature can easily melt to weld metal.

Current lead-free solder

On the market today, lead-free solder is classified into 3 main types follows:

Pure lead-free solder

Pure lead-free solder is a type of solder made from 100% pure Tin (Sn). This type has a rather high melting point, close to 400 degrees Celsius.

Silver solder lead

Tin silver solder is a solder that contains silver in its composition. The composition of this lead includes 96.5% tin, 3% silver, and 0.5% copper. There are also manufacturers that will increase to 36% silver, 62% tin, and 2% copper. Tin silver solder has the advantage of good electrical conductivity and less resistance to deformation. At the same time, the degree of tensile strength is also much higher than that of solder on the market today.

Lead-free solder tin wire containing rosin

Finally, a lead-free solder coil containing a rosin core. This type melts at a fairly high temperature, around 200 – 250 degrees Celsius. The soldering tin contains turpentine to help the solder stick better, is easy to solder, gives the weld a high gloss, and keeps it for a long time discolored. At the same time, the ability to conduct electricity and heat of the weld remains the same.

Is lead-free solder safe for users?

The composition of lead-free solder will not contain the element lead (Pb). So when welding, the gas produced will not be toxic to the human body when inhaled, ensuring the health and safety of the welder.

And especially, when soldering metal with lead-free solder, it will prevent the risk of lead poisoning for users. Therefore, devices using this type of material will not cause harm to the user.

In fact, with such high safety, this material has gradually replaced leaded solder. And it has been most widely used in plumbing, circuit boards, and electronic components for users.
