>
>Hello:
>
>Our customer made a mistake on their print.  Instead of specifying
>immersion gold, they specified Hot Air Solder Levelled.  Now they have
>LOADED boards that they want to get immersion gold on.
>
>Has anyone done this?  The questions I have off the top of my head are:
>1. How do you protect the components from the immersion gold?  Would
>conformal coat work?
>2. Do you have to strip the solder first, or can you go gold over
>solder?
>3. What, if anything, would all this do to reliability?
>
>Thanks for your help....
