Thank you so much to all contributors, I will refuse the use of bright tin
for that application. There are too many aspects that make it too risky for
that application.

Regards,

Cedric

Objet : [TN] Bright tin

Hello all,

I've been proposed Bright Tin as PCB finishing. It is the first time I've
heard about this plating for PCB. 

Is someone is familiar with this process and could expose drawbacks and
benefit? 

Do you confirm that it is an electroplating process? Do I need to specify a
Nickel barrier or something lie that underneath the tin layer? Is the
thickness of tin is critical and has to be monitored carefully? 

I'm also concerned about tin whiskers with bright tin as it as been banned
from the plating of connectors and components due to its propensity to the
growth of whiskers.

Ok, it's a lot of questions!  I just want to be advised on what is important
to know about that subject.

Thanks in adavance for your bright advice.

Cedric ORAIN
