Franz,

Does this mean that a Hot Air Leveled Sn Cu finish has been discounted.

Dear all,

for a leadfree finish solution the market favours Sn or SnBi. One problem
using Sn is the creation of Whiskers.
I just heard about an underplating of nickel to solve that problem.
Are there any further informations/ experiences on this topic?

Franz
