Recycled Aluminium From Beverage Cans As An
Alternative To Hazardous Lead In Soldering

Lead (Pb) based solder in assembling electronics components
are hazardous and dangerous for humans. Environmental
Protection Agency has strictly banned the use of lead solder
alloy due to its toxicity. The use of silver (Ag) in solder is one
of the best alternatives for replacing lead. Unfortunately, the
expensive price of Ag will intensively increase the cost in mass
production of electronic devices. In schools around Kuala
Lumpur, beverage cans are found abundantly. Thus, it is the
perfect solution to reuse the waste and subsequently reduce the
toxicity of soldering properties. The number of cans collected
from the school compound is more than 120 cans per week.
These amounts of cans are considered plentiful proving that the
source of recycled aluminium in the society is not a problem.
Moreover, the aluminium cans are not disposed or recycled
properly which causes a nuisance to the society.
In this project, new composite solder Sn-0.7Cu with additions
of recycled aluminium from beverage cans is suggested to be
used for replacement. The addition of aluminium in Sn-0.7Cu
from recycled beverage can produce the same properties as
other sources of aluminium. Furthermore, it has low melting
point and also a good corrosion resistance. Moreover, it is
more ductile as a soldering material. The use of aluminium
from beverage cans reduces the industrial cost as they are
reused and recycled. Most importantly using recycled beverage
cans is the solution to a greener and safer environment.
