I agree.

The question was 'as an alternative to HASL".

As an alternative to HASL immersion tin can be very good with all the
benefits mentioned earlier.

One problem to watch out for is compatibility with solder resist - it can
attack some resists causing problems - use a robust resist and you should
see few problems.  Like the man said - try it and see what you think.

It's the old horses for courses - immersion gold might be the right finish
for your application but I would definitely try immersion tin first.

                Hello folks. Yes it's been a while since i have responded to
any talk on the
                net....majority of the time....i like to talk about things i
have experienced
                first hand...u know....hands-on.....cuz like they say....
talk is cheap. :o)

                For those who aren't aware of the fact.....the company i
work for...has been
                marketing white tin for the last 5 years, and our success
speaks for itself.

                It amazes me when i see someone asking " does anyone have
info on white tin?"
                then getting an answer back...." I would suggest immersion
gold".

                Hello!!!!......are we all on the same planet here? If that
someone did try
                white tin where immersion gold should have been used in the
first
                place.....well.....the answer speaks for itself.

                In all my years of working with "white tin" i don't believe
the manufacturers
                of the product ever implied that white tin can replace
immersion gold....but
                when will people ever sit down and try to understand that
those are two
                different applications.....maybe never...and maybe we'll
keep on getting
                responses like.......i would suggest immersion gold.

                If there are parties interested on more info or references,
please do e-mail
                me.........

                Thank you for your time
