Victor,
I haven't seen and TechNetter responses but I'll give you my two cents. The
IMC thickness numbers you heard sound much too high. I think the IMC
thickness should be half as thick as those numbers.

Subject: [TN] IMC Formation Thickness in OSP
Fellow TechNetters:
What is the acceptable guideline for IMC Formation thickness on OSP after
2x rework.. IPC-4555 is still pending. I've heard of 3-5 microns on first
pass and 5-10 microns on 2x RW. All comments/suggestions welcomed.
Victor,
