Cleanliness Testing Samples - What to Use?

Electronics Forum | Mon Oct 04 20:06:31 EDT 2004 | davef

We know SIR coupons are not ROSE coupons, but coupon boards are: * IPC-B-24 (copper and HASL, FR-4 and polyimide) * IPC-B-36 (bare copper and HASL, FR-4 and polyimide) * IPC Phoenix board (bare copper, FR-4) * IPC-B-25A (FR-4, bare copper only)

No clean with higher SIR values

Wow, good luck. None of my test results would be helpful since we use IPC-B-24 test boards as received from our board suppliers so we have a clear understanding of what we're shipping customers, not necessarily paste performance alone. We'll only cl

Electrochemical Methods to Measure the Corrosion Potential of Flux Residues

Technical Library | 2017-07-27 16:51:57.0

Reliability Expectations of Highly Dense Electronic Assemblies is commonly validated using Ion Chromatography and Surface Insulation Resistance. Surface Insulation Resistance tests resistance drops on both cleaned and non-cleaned circuit assemblies. It is well documented in the literature that SIR detects ionic residue and the potential of this residue to cause leakage currents in the presence of humidity and bias. Residues under leadless components are hard to inspect for and to ensure flux residue is totally removed. The question many assemblers consider is the risk of residues that may still be present under the body of components.

Divergence in Test Results Using IPC Standard SIR and Ionic Contamination Measurements

Technical Library | 2017-07-13 16:16:27.0

Controlled humidity and temperature controlled surface insulation resistance (SIR) measurements of flux covered test vehicles, subject to a direct current (D.C.) bias voltage are recognized by a number of global standards organizations as the preferred method to determine if no clean solder paste and wave soldering flux residues are suitable for reliable electronic assemblies. The IPC, Japanese Industry Standard (JIS), Deutsches Institut fur Normung (DIN) and International Electrical Commission (IEC) all have industry reviewed standards using similar variations of this measurement. (...) This study will compare the results from testing two solder pastes using the IPC-J-STD-004B, IPC TM-650 2.6.3.7 surface insulation resistance test, and IPC TM-650 2.3.25 in an attempt to investigate the correlation of ROSE methods as predictors of electronic assembly electrical reliability.
