CM extractable ionic-residue measurement

GEN3 Systems Limited · Packaging processes and engineering validation

Purpose: Humidity-related leakage studies benefit from comparable extractable-residue data under controlled sampling and extraction conditions.
Technical approach: CM circulates extraction liquid and measures conductivity, offering ROSE and PICT methods with temperature/CO2 compensation.
Scope of use: Match compatible boards/components, specimen dimensions, area, liquid volume and procedure to the model/method.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
It does not identify individual ions or buried CAF. PICT is not total residue content; excessive extraction can change results.
What to prepare
BLNKK suggests cleaning history, surface-area calculation, material compatibility, blanks and controls with a fixed procedure.
Confirm with the supplier
Confirm ROSE/PICT selection, liquid/temperature controls, area/volume, calibration and duration criteria.
Public evidence: The body and FAQs distinguish ROSE from PICT’s reproducible residue extraction for monitoring process changes.
