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

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.

Anyone can help me how many percentage of blowholes and pinholes if i do the followings: 1. Increase copper plating thickness more than 25 microns. 2. Pre Baking of PCB to remove gassing by drying out the PCB's

Can someone look this over and see if this helps?? ****************************************************** I read the e-mail threads and I think the respondents are all mixed up on the units of measure. the print reads: Gold Plate (80 mocroinches m

Is there somebody who knows if there is a machine already available in market that can transfer die from wafer to waffle tray. This machine should a stand alone type or can be integrated to some P&P machine. What I'm trying to say is just like the on

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

Please check with Fab house, what is the thickness of the immersion gold if the gold thicknesss is less than say 2.5 micron, you will found dewetting or open. It is recommend the gold thickness is around 5 micron. Good Luck Dason

Hi All, Need your suggestions on the below queries: 1. What will happen if the Au thickness maintained @ 0.5 to 1 micron (Where Ni Thick is within 3 to 5 microns) in 0.2mm Thickness FR4 PCB. 2. Is there any solder quality affcted during Reflow Solder
