Graham brings up a good point. When a stringent end-item ionic cleanliness
requirement is levied, it can be very difficult to meet consistently if you
have either absorbed contaminants in the solder mask or laminate, or if you
have a less than fully cured mask, a ROSE test will be hard to pass. If the
mask is not fully cured prior to HASL, they tend to absorb more flux and
leach it out in a subsequent ROSE test.
