Priority items to confirm · 4
01Traceable evidence availableUnconfirmed
Have circular reconstituted-wafer dimensions, thickness and stack been confirmed?
Check diameter, mold material, die layout and process stage; rectangular panels require their own configuration.
Update engineering conditions →02Traceable evidence availableUnconfirmed
Are free and chucked states measured at matched temperatures, references and locations?
Document faces, center/edge locations and support definitions; a room-temperature bow value does not represent loading shape.
Update engineering conditions →03Traceable evidence availableUnconfirmed
Are thermal conditioning, vacuum chucking and timing histories traceable?
Record support, vacuum, dwell and recovery. If thermal conditioning was performed, also record material temperature limits and oxidation sensitivity; explicitly state when it was not performed. Momentary flatness does not establish a lasting improvement.
Update engineering conditions →04Traceable evidence availableUnconfirmed
Have downstream chuck, transfer and acceptance limits been confirmed?
Match tool size, pick/place, flatness, vacuum and fracture risks to the actual wafer.

View source notes and limits
Published limits are ±5 mm input and typically <500 µm output. Up to 25 UPH is product-dependent; −10°C to +260°C is station-dependent.
Scope and limitations Typical output and maximum throughput are not guarantees for every wafer. Adjustment does not establish that material or structural causes are resolved. What to prepare BLNKK suggests preparing wafer dimensions, stack details, warpage measurements and downstream thermal budgets, then evaluating representative samples. Confirm with the supplier Confirm model, stations, recipes, acceptance criteria and oxygen-free options. Discuss material compatibility and subsequent reliability checks.

View source notes and limits
The product page and brochure both specify bow, warp and thickness measurements, with scans under one minute. Accuracy depends on the sensor and warpage; the two sources give different heating specifications.
Scope and limitations Published sources do not establish continuous reflow imaging. Their heating ranges and uniformity differ, so the current configuration must be confirmed. What to prepare BLNKK suggests preparing wafer dimensions, material and surface details, expected warpage, support conditions, measurement temperatures and repeatability targets, with representative samples. Confirm with the supplier Confirm the current heating range and uniformity, sensor and calibration conditions, stabilization time, actual scan time and export format.

What to do next
No result provided. Clarify key conditions before arranging an assessment.
- Have circular reconstituted-wafer dimensions, thickness and stack been confirmed?
What to prepare
- The tool supports 200 or 300 mm molded, reconstituted wafers, particularly FOWLP. ERS positions it for R&D laboratories and technology-ramp pilot lines. 200/300 mm reconstituted wafer stack; conditioning history, shape, oxidation sensitivity and downstream limits
- For process comparisons on 200/300 mm silicon, molded and other wafers; confirm surfaces and configurations. 200/300 mm wafer geometry, sensor configuration, support or vacuum boundaries and required temperature profile; confirm the current model’s heating specification
