LHU constant-climate cabinets for moisture conditioning

ESPEC · Reliability qualification and failure analysis

Purpose: New delamination after reflow calls for comparing moisture and drying histories under matched reflow conditions.
Technical approach: LHU cabinets provide controlled temperature/humidity exposure and record setpoints and process values to document conditioning history.
Scope of use: Package moisture-conditioning studies, with the model selected for the required environmental combinations, specimen load and measurement setup.
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
Reflow, drying and delamination localization require separate arrangements. Cabinet settings do not establish specimen conditions, moisture equilibrium or package qualification.
What to prepare
BLNKK suggests documenting specimen size and count, moisture/drying history, target environment and duration, with matched reflow profiles and before/after defect checks.
Confirm with the supplier
Confirm the selected model’s temperature/RH combinations, loaded-cabinet performance, specimen-temperature measurement and data export. Ask which functions require options.
Public evidence: ESPEC’s product page and July 2024 catalogue describe control ranges, recording and measurement options. Catalogue performance conditions use an unloaded cabinet at specified ambient conditions.
