Hello everyone

I am working on a web site and I need your input to help me build a
section of it. This is not a sales presentation I just need your input
as fellow professionals dealing with the ROHS no lead problem.

I am in need of Pictures of your solder joint failures.

I need also what caused the error if you know it, if not, I can help
you access it.

I need these pictures to be only of the solder joint area with no
proprietary items shown in the picture.
I need them to be non copy written meaning that you took them, you own
them, and you are transferring ownership to me and certifying that the
pictures taken are originals and that you are licensing me to use them.

I will need information on the process you used and the type of solder
and flux chemistry you used. Also in most cases the PCB material
(Ie..FR4, IS410 ETC...)

Board plating also can help and inf. on the component finish will help
me also.

I am building a database of problems and solutions using different
solder mixtures and profiles.

This will help our community of engineers to have one more
comprehensive resource of shared knowledge.

Please send to:

I don't have solder joint failures

Is there a problem? I've been using lead free solder for a while now
and as long as you adapt to the need for a slightly higher soldering
temperature and use good quality solder it makes very good joints.

I'll be happy to recommend a good lead-free solder if you are having
problems.

You're asking for proof of poor workmanship. I've not had any problems
with lead free solder and I'm an amateur. I'd suggest you just mention the
usual ways of ensuring a decent solder joint.

Contact CORGI .. I'm sure they can provide list of people in your area who
are capable of creating poor solder joint failures.
