Acceptance Criteria Ion Chromatography testing?

Electronics Forum | Thu May 31 21:43:44 EDT 2012 | davef

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days

Ionograph or Omegameter

Both are equally efficient process control tools. Neither is particularly effective in testing ionic contamination. The best way to sell your customer on allowing you to do this is to show them that you understand the WHOLE process and are able

Electromigration Testing

Electronics Forum | Mon Jun 28 10:03:22 EDT 2004 | davef

First, welcome to your new job. Second, IPC-TM-650 2.6.14 is only loosely an �Ionic Contamination (Electromigration) Test�. * Electromigration Test, IPC TM 650 2.6.14, * Ion Chromatography for Ionic Cleanliness, IPC TM 650 2.3.28 Third, I

SIR starting point...?

Electronics Forum | Mon Oct 21 22:15:36 EDT 2002 | davef

First, SIR data is heavily dependant on the test pattern selected. Be very careful when comparing the results of resistance readings taken from different geometric patterns. Second, if yer talkin': * Bare boards, yupper. * Finished assemblies impor

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

Ion Chromatography (IC) qualification

Thanks for the reply. R/O/I is ROSE / Omegameter / Ionograph which is used as a baseline for Ion Chromatography.

Ionic Contamination Acceptance Criteria

Electronics Forum | Thu Dec 16 09:59:47 EST 2004 | saragorcos

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

Cleanliness test

Electronics Forum | Thu Jan 02 11:35:30 EST 2003 | Richard

Cleanliness test � �Area Grid Arrays�. Evaluation of residues� resistivity in a specific location on the board. (As compared to �Solvent Extract� evaluation.) We are: SMT assembly, using standard �water soluble� process with micro BGAs (example: C

Ion Chromatography (IC) qualification

Electronics Forum | Wed Apr 13 09:15:07 EDT 2011 | blnorman

Have used IC for years, but I'm not familiar with that, ROSE maybe. Its a stretch, but maybe R/O/I would be rosin/resin, organic, or inorganic for the type flux being used?

Board Cleanliness Monitoring

Electronics Forum | Tue Nov 15 21:15:22 EST 2005 | davef

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
