Have you talked to people [Specialty Coating Systems 800-356-8260 317-244-1200 scscoatings.com/parylene_equipment/omegameter.aspx] about repairing your Omegameter? Major differences between the testers are: * Ionograph measures conductivity, while t

Alcohol Content: Ionographs don't like to have the alcohol content too far off from 75%. If that happens, either way, your resistivity will be low. Temperature: Ionographs don't like to be rushed. Stay focused on a proper warmup time. If you don't,

Hello all, Any idea what is causing low resistivity in ionograph?

CMI International says, there are five basic, non-destructive methods of determining coating thickness. Each method was devised to achieve cost-effective, accurate, and repeatable results. Those methods are: * X-Ray fluorescence * Eddy-current * M

I want to know how you measure capacitance and resistance to 01005 components?Is there such a machine for automatic measurement of component values on PCB? We have a lot 01005 components and we lose time to measure first panel components...I'm inter

I have dealt with it before and usually it's consistent, so you use some simple math to work around the issues. Now, if you have so much variability between different locations on your board for resist thickness, HASL thickness, etc., that it fouls

We have an AUREL CS1222 machine to measure the thickness of the solder paste deposited on a bare board by a stencil printer. This device has a laser beam that has to be put on the pad where you want to measure the solder paste thickness. The measure

Ionograph measures conductivity while the Omegameter measures resistivity. They both accomplish the same task in terms of ionic contamintation detection, but go about it a different way. One is really no more accurate than another. For more informati

Casimir: Resistivity of Solvent Extract (ROSE) testers measure ionic contamination by washing boards with a DI water/IPA solution. (No-clean people: Stop and go on to something else.) The testers are process control instruments used to monitor a
