Are you looking to measure foil thickess or etched aperture depth? Using an indicator, you would mount it to a stand / surface plate, then you zero the indicator on the plate surface, then place the foil on the surface and indicate to the top surface of the foil. This will give you the foil thickness. -----Original Message----- From: Leland Woodall [mailto:[log in to unmask]] Sent: Wednesday, October 14, 2009 1:42 PM To: Glidden, Kevin; TechNet E-Mail Forum Subject: RE: [TN] Stencil Thickness Verification Kevin, I looked at that device online, and can't understand how I could use it to check the depth of an aperture. What am I missing?

For example, mitutoyo p/n 1923 in a range of 0 - .05 in, .0005 graduations. -----Original Message----- From: Leland Woodall [mailto:[log in to unmask]] Sent: Wednesday, October 14, 2009 1:22 PM To: [log in to unmask] Subject: [TN] Stencil Thickness Verification TechNetters, Does anyone in the industry verify their framed stencils for thickness upon receipt at their facility? If so, could someone please share what kind of tool they use? I'm having difficulty finding such an animal that will accurately distinguish between 5 and 6 mils.
