Capabilities do not guarantee sample localization or specify mold-sealing recipes.
- ESPEC · LHU constant-climate cabinets for moisture conditioning ↗
View source notes and limits
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.
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.
- Resonac · Resonac CEL/GE EMC for organic-substrate packages ↗
View source notes and limits
The page describes reflow-crack resistance and low molding warpage, with separate typical-property tables.
Scope and limitations Published characteristics do not establish an MSL rating or delamination-free target package. Typical values are not universal guarantees; changing material does not repair existing delamination. What to prepare BLNKK suggests recording grade, surfaces/pretreatment, molding/cure and moisture/drying/reflow history, with pre/post-reflow C-SAM comparisons. Confirm with the supplier Confirm grade availability, molding window, moisture-absorption and adhesion data, and validation criteria for the actual stack.
- Yield Engineering Systems · VertaPrime PLP silane-vapor panel treatment ↗
View source notes and limits
The named description documents deposition/curing chambers and surface-modification uses.
Scope and limitations Silane treatment does not qualify every molded interface or guarantee no moisture/reflow delamination. Confirm actual thermal configuration and compatibility. What to prepare BLNKK suggests preparing substrates/films, surface condition, chemistry, temperatures/wait times and adhesion/pre-/post-moisture comparisons. Confirm with the supplier Confirm deposition/cure recipes, thermal/support configuration, compatibility and treatment-to-use window; discuss interface-strength and reliability validation.
- NETZSCH Analyzing & Testing · STA 509 Jupiter paired mass and thermal events ↗
View source notes and limits
NETZSCH describes simultaneous mass and thermal analysis.
Scope and limitations Mass loss is not automatically water. Small specimens do not establish package moisture diffusion, locate delamination or define a universal bake schedule. What to prepare BLNKK suggests preparing paired wet/dry specimens, storage and treatment histories, composition, intended programs and corresponding package-failure observations. Confirm with the supplier Confirm the Select sensor, furnace, atmosphere and calibration. For identifying evolved species, confirm gas-analysis coupling, detection scope and interpretation.
- Shin-Etsu Chemical · Shin-Etsu KBM-403 epoxy silane coupling agent ↗
View source notes and limits
The named selection guide identifies epoxy functionality, additive use and glass-fiber/resin interfaces.
Scope and limitations Water-resistance/adhesion positioning does not establish MSL/reflow qualification or repair existing package delamination. What to prepare BLNKK suggests surface, resin/filler, addition/treatment and cure history alongside dry/wet adhesion and reflow results. Confirm with the supplier Confirm dosage, solvent/hydrolysis/treatment, storage/safety and compatibility using formulation-specific specimens.
- Rigaku · STAvesta simultaneous mass-loss / thermal analysis ↗
View source notes and limits
Rigaku documents TG-DSC, furnace configurations and GCMS/FTIR expansion.
Scope and limitations Mass loss may reflect several volatiles or decomposition. TG-DSC alone does not identify water or a delamination root cause; gas analysis needs suitable configuration. What to prepare BLNKK suggests preparing material/sample-location details, moisture/drying history and comparable heating programs. Confirm with the supplier Confirm preparation, furnace/atmosphere selection, baseline/calibration and whether combined gas analysis is needed.
- Nippon Kayaku Co., Ltd. · Nippon Kayaku NC-3000 epoxy formulation resins ↗
View source notes and limits
The official epoxy page names NC-3000 variants and describes semiconductor uses and lead-free solder heat resistance.
Scope and limitations Resin information does not establish finished-EMC qualification, assembly MSL or interface reliability, or guarantee elimination of delamination. Other resin families' low-water-uptake or low-warpage claims do not transfer. What to prepare BLNKK suggests preparing formulation, filler/hardener, cure and moisture history, contact surfaces and dry/wet interface observations. Confirm with the supplier Confirm the grade, available material/formulation data, cure conditions and assessment approach for the actual substrates and moisture-delamination concern.
- MA-tek · Multi-technique failure analysis and reliability verification for advanced packaging ↗
View source notes and limits
The packaging service page lists non-destructive inspection, cross-section/material analysis and tests including TC, HAST and HTS. The SAT page explains acoustic inspection of delamination, voids and cracks; these document service scope.
Scope and limitations A defect image or compositional difference may not establish root cause on its own. SAT penetration and detectability depend on the specimen; water coupling and destructive preparation need prior agreement. What to prepare BLNKK suggests preparing the failure symptoms, package structure and suspected locations, moisture/reflow/cycling history, control samples and existing electrical or imaging results, plus acceptable preparation methods. Confirm with the supplier Confirm analysis sequence, sample count/consumption, interface accessibility, test conditions and interpretation criteria, raw-data/report deliverables, and the laboratory performing the work.
- MacDermid Alpha Electronics Solutions · PackageBond copper-polymer adhesion promotion for panel-level packaging ↗
View source notes and limits
The page gives HVM and MSL-1 claims without stack or test conditions; supporting details need supplier confirmation.
Scope and limitations Improved interface adhesion does not guarantee global panel-warpage improvement. MSL-1 claims need the actual stack and test conditions. What to prepare BLNKK suggests preparing delamination location, copper/polymer types, pretreatment and process sequence, moisture/reflow histories and reference samples. Confirm with the supplier Request grade, treatment/cleaning conditions, compatibility and reliability-test stack, protocol, acceptance criteria and data.
- Mitsubishi Chemical Group · jER epoxy resins for packaging formulations ↗
View source notes and limits
The jER page describes resin types and curing, while the separate packaging-materials page identifies encapsulant and laminate applications.
Scope and limitations jER is a resin family, not a finished adhesive qualified for the intended package. The reviewed pages do not establish grade-specific Tg, CTE or moisture/reflow interface results; claims for other packaging products cannot be transferred. What to prepare BLNKK suggests preparing resin/hardener grades, filler loading, cure history, contacting surfaces and Tg/CTE/stress targets, with interface-coupon results before and after moisture exposure and reflow. Confirm with the supplier Confirm suitable grades, formulation compatibility, processing/cure conditions and available physical-property and moisture-conditioned interface data. Agree sample tests and reliability acceptance criteria.
