01Free / supported maps registerableUnconfirmed
Are same-coordinate panel maps available in free state and under specified support?
Record orientation, support points, and references. Free-state bow cannot replace residual topography on the chuck.
Update engineering conditions →02Contact and loading records registerableUnconfirmed
Can loading-failure locations be mapped to chuck contacts, vacuum, and handling records?
Record equipment model, support surface, orientation, and failed step. Do not set universal vacuum or clamping forces.
Update engineering conditions →03Comparable timing and loading conditionsUnconfirmed
Are post-mold timing, temperature, and loading orientation fixed and repeatable across comparison panels?
Different thermal histories, waits, or orientations prevent direct chuckability comparisons. Retain curvature-reversal observations separately.
Update engineering conditions →04Integration limits traceableUnconfirmed
Have candidate carrier dimensions, CTE, adhesion / debond, and downstream equipment limits been checked?
Confirm evaluation scope only. Glass rigidity does not establish damage-free debonding or vacuum holding on arbitrary equipment.

- Akrometrix · Measurement Vision Technologies ↗
View source notes and limits
Shadow Moiré measures temperature-dependent warpage of continuous surfaces; DFP measures discontinuous surfaces and height differences, including solder balls.
Optical capabilities do not establish successful chucking, actual contact gaps, or reflow bonding. Reference datums and support conditions must be defined.
- Onto Innovation · JetStep S3500 product overview ↗
View source notes and limits
The official product overview lists warped-panel handling, dynamic-focus, and die-shift-correction options.
Public manufacturer options provide no panel-specific chuck pressure, deformation acceptance, or handling-compatibility specifications.
- SCHOTT · Glass carrier ↗
View source notes and limits
Explains glass-carrier mechanical support, expansion matching, and transparency for laser debonding.
Uses and material capabilities do not validate panel adhesion, debonding, temperature, or equipment compatibility.
- Toray Engineering · TRENG-PLP glass-panel coating and cure ↗
View source notes and limits
The product page supplies coating/handling information; the December 2024 launch describes glass-interposer use and the announced sales stage.
Scope and limitations Common-shape correction does not accept arbitrary warpage or permanently remove material stress. Example uniformities and optional inspections are not universal outcomes or standard configuration. What to prepare BLNKK suggests preparing dimensions, temperature-dependent shape, material viscosity, target thickness, cure history, and contact/contamination limits. Confirm with the supplier Confirm allowable warp, material/temperature windows, drying/curing and inspection options, then plan coating and handling trials.
- Tokyo Seimitsu (ACCRETECH) · AD3000TW fan-out substrate blade dicing ↗
View source notes and limits
The product body documents package-substrate design, frame handling and work dimensions.
Scope and limitations Size/material coverage does not qualify arbitrary warpage or stacks, nor guarantee no chipping. Validate actual workpiece shape and cutting damage. What to prepare BLNKK suggests preparing dimensions/warpage, stack/thickness, streets, frame/clamping, blade/feed/water conditions and kerf records. Confirm with the supplier Confirm fixture compatibility, blade/spindle options, allowable warpage/process conditions and kerf, chipping and handling acceptance methods.
- TOWA Corporation · FWC1020 thermal flattening before singulation ↗
View source notes and limits
The portfolio provides thermal units/dimensions; the dedicated page identifies pre-singulation correction.
Scope and limitations Descriptions do not guarantee permanent flattening or elimination of thermal reversal, nor large fan-out-panel compatibility. Measure retention and material damage. What to prepare BLNKK suggests preparing material/thickness, temperature-dependent shapes, allowable thermal history, support/handling and post-correction shape-versus-time data. Confirm with the supplier Confirm heating/cooling recipes, support/temperature measurement, acceptance and waiting time; discuss reliability and downstream singulation validation.
- ASE · ASE stress and thermal characterization ↗
View source notes and limits
The official lab page explicitly lists wafer/panel warpage and separates modeling from measurement services.
Scope and limitations Published capability does not establish every panel size or fixture. Supported shape cannot replace free shape or guarantee handling acceptance/flattening. What to prepare BLNKK suggests stacks, process/moisture history, temperature/time and consistent coordinates/free-or-supported states for comparable records. Confirm with the supplier Confirm site/acceptance, sizes/fixtures, coverage/resolution, temperature settings and report format.
- ZEISS Industrial Quality Solutions · ATOS Q panel-scale geometry comparison ↗
View source notes and limits
The Industrial metrology page documents 3D scanning and measurement fields.
Scope and limitations Point spacing and point count are not measurement uncertainty or demonstrated microbump resolution. Control support, temperature and registration so measurement-state changes are not mistaken for warp. What to prepare BLNKK suggests preparing dimensions, surfaces, supports, temperatures, handling stages and datum definitions. Identify target regions and warp scale; provide existing scans or repeatability data if available. Confirm with the supplier Confirm sensor/lens selection, field stitching and any surface preparation. Agree on repeatability and uncertainty checks and how free versus supported states will be compared.
- Corning · Precision glass carriers for lower-warpage advanced packaging ↗
View source notes and limits
The current series page lists CTE choices spanning 3.4–12.6 ppm/°C; January 2019 sheets distinguish individual families. Up-to 40% process-warp reduction is a supplier claim without a published universally applicable test basis.
Scope and limitations Glass families have different specifications; a series-wide CTE range does not apply to every grade. Validate the product/carrier/adhesive/thermal process together rather than assume 40% warp reduction. What to prepare Bring wafer/panel dimensions, stack-up and materials, temperature range, existing warp and handling conditions, plus temporary-bond adhesive and debond method to plan carrier selection. Confirm with the supplier Confirm glass family, dimensions, thickness, TTV/flatness and CTE specifications with test conditions. Ask about adhesive/debond compatibility, edge strength, reuse and actual-process trials.
- Yield Engineering Systems · VertaCure PLP vacuum curing for low-warpage panel processing ↗
View source notes and limits
The 2022 PLP brochure documents configuration and applications; the 2019 white paper explains polyimide vacuum-cure principles. Its quantitative comparison uses YES-PB12 and specific material conditions, not PLP performance qualification.
Scope and limitations Recipe, material and panel support require joint validation; improvement ratios from another model cannot be transferred. The brochure does not define the measurement state of “Warpage ≤3 mm one side,” so it is not a guaranteed post-cure result. What to prepare BLNKK recommends preparing panel dimensions, materials/film thicknesses, soft-bake/cure histories, carriers and thermal budgets. Include existing cure, outgassing, stress and warp measurements to plan controlled comparisons. Confirm with the supplier Confirm current sizes/carriers, temperature/pressure windows, nitrogen/cooling options, uniformity and throughput validation. Ask the supplier to define the warpage entry, measurement state and material conditions before agreeing acceptance criteria.
- Unity Semiconductor · TMAP optical metrology platform ↗
View source notes and limits
The current EMD listing establishes the brand; an official UnitySC post names modules and measurements. Full model and module specifications remain unverified.
Scope and limitations Configurability does not establish every panel format or buried-defect inspection capability. Readable current sources do not establish a specific panel-warpage measurement range. What to prepare BLNKK suggests preparing target features/thicknesses, stacks, formats and handling. For panel topography, add expected warp, sampling areas and reference measurements. Confirm with the supplier Request the current model/module datasheet. Confirm principles, formats, ranges and calibration, then assess repeatability, correlation and exports using representative samples.
