- Kulicke & Soffa · Thermo-Compression Bonding ↗
View source notes and limits
The official page describes heat-and-pressure TCB with temperature, pressure, and tilt control, noting open risk with under-compression and short risk with over-compression.
These are general technology and supplier-capability statements, not recipes or yield guarantees for this HBM structure.
- ASMPT · Thermocompression Bonding with Active Oxide Removal ↗
View source notes and limits
Official resources describe AOR TCB as fluxless bonding using active oxide removal for clean, residue-free interconnects and fine-pitch HBM stacking.
Supplier claims do not establish oxidation or flux as the cause and provide no sample-validation results.
- ASE · Failure Analysis Lab ↗
View source notes and limits
The official page lists microbump cracks, voids, cold joints, bridges, electrical localization, nondestructive inspection, and sections / FIB.
Capabilities do not guarantee resolution, success, or root-cause determination for these fine-pitch HBM samples.
- Yield Engineering Systems · VeroTherm FAR XP formic-acid vacuum reflow ↗
View source notes and limits
The current product page documents reflow architecture/applications; the corporate page confirms formic-acid positioning.
Scope and limitations Customer-qualification or no-defect claims do not guarantee this project. Mass reflow is not localized TCB contact-force control. What to prepare BLNKK suggests preparing solder, bump/joint geometry, oxide conditions, die thickness/support, measured thermal histories and acceptable atmosphere conditions. Confirm with the supplier Confirm formic-acid/vacuum recipes, compatibility, thermal windows and measurable process limits; define wetting, void, cross-section and reliability validation.
- ASE · ASE microbump and package failure analysis ↗
View source notes and limits
The official laboratory page names micro-bump defects and non-destructive, localization and destructive-preparation capabilities.
Scope and limitations Listed capabilities do not guarantee detection or root-cause determination. Sectioning/FIB preparation may alter evidence. What to prepare BLNKK suggests preparing coordinates, process stages, layers/materials, electrical records and controls, planning non-destructive observation before sampling. Confirm with the supplier Confirm laboratory, sample acceptance, resolution, sampling/destructive risks and report/follow-up validation scope.
- JEOL · JIB-PS500i site-specific FIB sampling ↗
View source notes and limits
The named page documents FIB/SEM and preparation functions, distinguishing sampling/automation/EDS options.
Scope and limitations Destructive local preparation can introduce ion damage/redeposition. A lamella neither proves the open's cause nor represents every contact. What to prepare BLNKK suggests preparing electrical coordinates, layers/metals, section direction, prior images and controls, planning protection and sampling. Confirm with the supplier Confirm mounting, sampling/transfer options, ion-damage control and downstream TEM/EDS or other analysis responsibilities/configurations.
- Nippon Kayaku Co., Ltd. · Nippon Kayaku NK E-cleaner SO C175 flux cleaner ↗
View source notes and limits
Nippon Kayaku identifies SO C175 as a flux cleaner, without a published HBM/TCB cleaning window or qualification result.
Scope and limitations It does not repair non-wetted joints or establish access to buried interfaces. Conditions for adjacent post-ashing or resist-removal products do not apply to C175. What to prepare BLNKK suggests preparing flux, thermal history, gaps, residue locations and exposed metals/polymers. Existing cleaning records, residue images or ionic-contamination results can support comparisons. Confirm with the supplier Confirm flux/material/gap suitability and concentration, cleaning, rinse and dry conditions. Agree on residue, corrosion, ionic-contamination and electrical checks.
- ASMPT · FIREBIRD die-level thermo-compression bonding ↗
View source notes and limits
The official page lists ±2.0 µm placement accuracy, handling cycles below 2 seconds and mixed wafer/tape-and-reel input. These figures do not establish complete-bond throughput or product yield; the 2024 presentation adds application context.
Scope and limitations Handling-cycle time is not completed-bond throughput. Controls alone do not qualify a particular bump, underfill or warped assembly. What to prepare Prepare die/substrate geometry, interconnects/materials, input format, warpage, thermal budget and quality/throughput targets. Confirm with the supplier Confirm configuration, compatible materials, temperature/force/time windows, full bond cycle and sample-based quality/reliability validation.
- Kulicke & Soffa · APAMA PLUS chip-to-substrate and chip-to-wafer thermo-compression bonding ↗
View source notes and limits
K&S reports qualification of the three processes at major OSATs. The page does not quantify customer-package warpage improvement or production throughput.
Scope and limitations Process qualification does not qualify every customer package. Public evidence provides no universal warpage tolerance, void-reduction or throughput guarantee. What to prepare BLNKK suggests preparing die and substrate dimensions, thickness and warpage, bumps, underfill, bonding flow, yield criteria and throughput targets. Confirm with the supplier Confirm the configuration, material route, temperature and force windows, process monitors, and accuracy, cycle time and yield measured on representative samples.
- Samsung Foundry · 3D X-Cube / 3D Cube vertical die-stacking platform ↗
View source notes and limits
Samsung's current platform page describes Cube-T microbump chip-on-wafer and TSV technology as ready for mass production for low-power 3D IC, while explicitly identifying Cube-H hybrid Cu bonding as under development.
Scope and limitations This is a foundry packaging platform, not a standard component, and T/H maturity differs. Public descriptions do not establish a specific stack's warpage, thermal resistance, yield or lifetime; project validation is needed. What to prepare Bring die/process-node information, interconnect and power needs, stack dimensions, cooling conditions, and test/reliability targets to discuss architectural trade-offs. Confirm with the supplier Confirm which T/H route, design rules and schedule are available for the design. Agree on thermomechanical modeling, bond/test validation responsibilities and access to relevant qualification data.
- SET · FC300 high-accuracy, high-force flip-chip bonder ↗
View source notes and limits
The product page lists ±0.3 µm post-bond accuracy, 1–4000 N force and 1 µrad pre-bond leveling; the October 2025 family brochure positions FC300 for fine-pitch R&D and pilot production.
Scope and limitations Nominal placement accuracy and force range do not guarantee a particular specimen’s bond quality or establish wetting/electrical continuity. The page and brochure give different minimum forces; available tooling and operating conditions need confirmation. What to prepare BLNKK suggests preparing die/substrate dimensions, bump metals and pitch, coplanarity, incoming topography and existing force–temperature–time profiles, together with post-bond alignment, electrical or cross-section results. Confirm with the supplier Confirm specimen/tooling configuration, force and temperature controls, accuracy acceptance conditions and process atmosphere, plus support for the proposed HBM/microbump trials and pilot operation.
- Hanmi Semiconductor · HBM TC BONDER thermocompression bonding ↗
View source notes and limits
HANMI’s SEMICON China 2026 listing on the SEMI event site explicitly includes HBM TC BONDER, separately from its 2.5D TC BONDER models and other bonding equipment.
Scope and limitations The verified evidence is a product list, not model-specific accuracy, temperature, force, throughput or material-window data. Specifications of separately listed 2.5D models should not be assigned to HBM TC BONDER. What to prepare BLNKK suggests preparing the intended HBM stack, die sizes/thicknesses, joint metals/pitch, NCF or other bonding materials, current thermocompression profiles and non-wet/open specimens for an initial discussion. Confirm with the supplier Request the exact model/version and force–temperature–time/alignment data.
