| Based on years'
research and practical experiences in tin solder
bars, combined with the direction of green and
environmental -friendly and requirements of reliable
products of the modern electronics field, we are
producing the lead-free tin wire with metals of
high purity. Under strict quality control, we
have effectively controlled the degree of oxidation
and impurity content of both metal and nonmetal.
With even and smooth surface, high purity, good
fluidity after melting, good wetting performance,
bright soldering spot and little oxidizing slag,
the product is applicable to all kinds of waving
soldering and manual soldering with requirements
of high-quality. We are researching and developing
on new products and providing selections of different
alloy proportions and different types.

ÎÞLead-free alloy into the important
point |
|
| To help transit to lead-free manufacturing,
we will provide guides on lead-free solder, which may be valuable
to you on your productions. |
 |
Please choose Sn/Ag/Cu, Sn/Cu¡¢Sn/Ag serial alloy because
they are best eutectic alloy among all |
| |
lead-free solders. With a good property
of lead-tolerance, it is more applicable to the gradual
|
| |
lead-free process of the complete material. |
|
Check the temperature-control stability of the lead-free
equipment to guarantee the smallest |
| |
difference in temperature at welding process. |
|
Design the nitrogen welding environment by the operation
of opening on the moulding board to |
| |
acquire the smallest difference in temperature. |
|
Pay attention to the reliability check after welding
operations, including electric performance |
| |
and check to the stress, thermal fatigue, creep and
damages by mechanical vibrations. |
|
Make sure that the alloy and thermal endurance property
of the Thread binding material matches |
| |
the tin solder. |
