IPC J-STD-001E Ionic Cleanliness Standard

Electronics Forum | Fri Aug 30 22:51:14 EDT 2013 | cvogel

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL. Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typi

since IPC-J-STD-001 RevH obsoleted the 1.56ug/cm2 UCL of ionic contamination tester in testing using ROSE test, how do you define the acceptable limit per PCB assembly? thanks

Ionic Cleanliness-No clean residues

Electronics Forum | Fri Dec 15 11:06:06 EST 2006 | Gman

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

You�re asking the wrong person to give remedial math lessons. Anyhow, here we go: * [1.56 microgram NaCl/cm^2]*[2.54 cm/in]*[2.54 cm/in] = 10.06 microgram NaCl/in^2 * [Omegameter] / [MIL-P-28809 Beckman / Markson] = [10.06 microgram NaCl/in^2] / [GS

Ion Contamination level allowed on Connectors

Electronics Forum | Tue Sep 21 13:24:17 EDT 2004 | GS

Hello, does any one please can tell me if any Standard says how much is the Total Ion Contamination ( ugr/NaCl sqcm equivalent, Br- in particular way) allowed on Connector surface/body ? (ie. DIMM connectors, and similar). Many Thanks in advan

Deionized Water Standards
