Hi All We have a customer that would like us to remove the Manufacture Logos and part#s from 4 parts on their assemblies (PLCCs and QFPs). Acetone and Alcohol were both tried with zero deterioration of the markings. I suspect the parts have been Laser Marked. What would you suggest Mechanical Abrasion? Chemical What type? marking Laser (we have access to one)? Volumes would be about 2000 ICs/month This would likely have to be done after placement (QA's request).
