So, I was wondering how thick 2 oz. Copper is supposed to be? I have heard 60 microns and 70 microns, but the PCBs that we have that are supposed to be 2oz Copper are 68.5 microns, the Customer would like at least 60 microns, but what is the reality

Might want to double check my figures, but my notes have 2oz copper at 2.8 mils or 71.12 microns in thickness. 'hege

2 oz copper should be 2 oz per ft^2 thick. There is no relationship between thickness and copper weight due to the effect of processing. Since this is a painful way of thinking about things, ppl have reached a compromise and talk about 'nominal thick

Yes Rick, you are correct, Zevatech HBA, PPM7 & > PPM9 were all designed and built by Swiss. That > was a long long time ago. Sorry, I guess I forgot about those old beasts. Then don't forget about the good old CATs and Microns made by Zevatech

I was wondering if anyone has had any experience with either the Esec Micron 2 or the RD Automation CDB-50? We currently have a Micron 2 (1997 build). We are using it for small batches of flip chip. We use the waffle pack feeder not the wafer loader.

I would like to talk with anyone that owns a Zevatech 570 or 575. I currently own 2 PM460's and am looking for a brief upgrade to a 570 or 575 before buying a 750 or 760. Any information will be helpful. Brian Morgan - VP Manufacturing

Hi Everybody My company is looking to buy some precision measurement systems to measure the height of flip chip bumps (nominal height of 100 microns). We are looking for a resolution of about 2 - 4 microns. Any help would be appreciated. Thanks Man
