Your Ionograph and Zero-ion Values are set by you. There is no raw pass of fail criteria only the limits you set up. Ionograph is great for bare board resistivity (salt) test just as a pass fail for incoming inspection but this is all per your facto

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

Hello All, Is Ionic Cleanliness testing using say an Ionograph on No-clean assemblies a valid test? If not, why? I understand factors like PCB cleanliness but is the 1.56ug/in2 IPC criteria valid for no-clean assemblies and can an Ionograph be used

Dave, Ionic contamination testers are considered to be a valuable tool to determine the cleanliness of both bare boards and post solder boards. There are some instances when SIR testing is more suitable for determining cleanliness than ionic contamin

Military and most commercial standards requires post-soldered boards to measure less than 10 �g/in of NaCl (14 when using an Omegameter, 20 on a Ionagraph, and 37 on a Zero-Ion). As Dave stated, 6.5 �g/in of NaCl is called out in Mil-P-55110 for ba

Wanted to inquire if anyone has a way to monitor cleanliness of boards that are assembled with a no-clean process. I'm aware that incoming board cleanliness can be monitored, however, I am after checking of cleanliness of boards after assembly. Wit

We understand that testing for ionic contamination and surface insulation resistance measure different properties. We assemble printed circuit boards for other companies. We will not get combs on 90% of the boards that we assemble. We have no custo

The EMPF published a nice article, now old but relative, to Cleanliness. www.empf.org Under Technical Docs The listing is ... RR0013 - An In-Depth Look at Ionic Cleanliness Testing - August 1993. Cal

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

A fairly painless method for monitoring cleanliness is Resistivity Of Solvent Extract [ROSE]. Equipment is: * Omegameter * Ionograph * Ion Chaser [Zero-Ion] Anyone who desires to use an Resistivity Of Solvent Extract tester should read EMPF repor
