I need your process pictures

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:

Mike,

Your intention to build up a database has some merit, but there are some
things you should let know potential contributors:

OK so far.

Pictures taken by employees in the scope of their work are usually owned
by the employer - do you want people to cross that line? Will
contributors get free access to that database?

This is usually proprietary information (I am referring to the process).

Are the contributors part of this community?

You are offering seminars etc. in the workfield of RoHS, so you will
have some gains from the content of this database. ( eBay item

Everybody is free to do what he/she wants, but people should know.

Michael

Why do you need ownership of the pictures? Why
is permission to use them not sufficient?
