I am looking at setting up dye penetrant testing of BGA solder joints.  I
have the methodology from IVF and they use a material called "Steel Red"
(which is in fact a "layout fluid".

I was wondering if anyone has any other suggestoins for dye penetrant or
layout fluid for this task.   I do want something "reasonably"
environmentally friendly, dries in a relatively short length of time (or
overnight at ambient) and good visibility/contrast with solder joints.

thanks in advance.
Jim
