Engineering conditions

Use 4 key conditions to see how the assessment order changes.

Record free and chucked shapes of circular reconstituted wafers before reviewing thermal conditioning, support, transfer and downstream acceptance. Unknown conditions remain pending; readiness does not qualify a solution or establish a root cause.

Assessment with your current conditions

Assessment order does not indicate endorsement or performance

The order changes only with conditions you confirm. Public information cannot establish suitability for your actual samples.

New test result? Update your assessment

After a controlled comparison, use the observed result to plan the next step.

A trend, recovery or correlation cannot establish root cause, exclude other failures or guarantee production results.

Current assessment and next steps

Based on reported conditions and public sources. Ready to assess does not establish sample applicability or root cause. Order does not identify the best solution.

Known conditions · 0

    Key unknowns · 4

    • 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.
    • 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.
    • 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.
    • Have downstream chuck, transfer and acceptance limits been confirmed?Match tool size, pick/place, flatness, vacuum and fracture risks to the actual wafer.

    1. 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

    ERS electronic

    Compare wafer-specific thermal conditioning and downstream handling acceptance for a molded reconstituted wafer.

    Basis: 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.
