A Story of environmental "Lead(Pb) Free Solder"

Himawari	I heard that "Solder" have been used for very long time. For example, it was found in old Roman excavations and it was also used to build a huge statue of Buddha.

Happy	Wow! So long!

Himawari	"Solder" is used for almost all the electric and electronic equipments, such as TV game machines and mobile phones. "Solder" is a kind of bond with electrical conduction.

Happy	"Solder" is so important for our life now.

Himawari	But "Lead(Pb)" used in solder is harmful to human beings and all the creatures.

Happy	I’m afraid of that. What will happen with "Lead(Pb)"?

Himawari	"Lead(Pb)" makes human beings ill and it also harms our environment in nature. It can wither plants away from the soil.

Himawari	Therefore, "Solder made with Lead(Pb)" is not allowed in Europe. Of course, in Japan and in other countries, it will be prohibited soon.

Happy	But, how can we manage without "Solder"?

Himawari	Yes. That will be a problem because we won’t be able to produce electrical equipments.

Happy	Then, why don’t we remove "Lead(Pb)" from solder?

Himawari	You are right. To remove "Lead(Pb)" is the key answer, but it was hard to find a suitable substitute for "Lead(Pb)". Many engineers and scientists worked and studied hard and finally they succeeded to produce "Lead(Pb) Free Solder".

Happy	I believe that was not an easy job.

"Lead(Pb) Free Solder" with five elements

Himawari	For example, this "Lead(Pb) Free Solder" is made with five elements! Tin(Sn), Silver(Ag), Copper(Cu), Nickel(Ni), and Germanium(Ge). It doesn’t harm human beings and our nature. Look! Flowers are blooming so beautiful.

Happy	Great! Then, there’s nothing to worry.

The harmful result of "Lead(Pb) Free Solder"against the environment is little.

Himawari

The Lead(Pb) free solder considers hard an effect on the environment though it is difficult to find out the Lead(Pb) free solder from the outside of the product.
How better the Lead(Pb) free solder material is than the previous Lead(Pb) solder!
I understand that it is important that each one of honest development and the research becoming the link to the future!
I do my best because I want to see beautiful earth in the future.
Don't you think so?
Let's find helpful thing for the environment of the earth together!
