BLNKK's current understanding
Please check the details- Object and structure
- Molded circular reconstituted wafers and chuck/support interfaces
- Stage of occurrence
- After debonding, before or after RDL, and during downstream transfer/loading; confirm the configuration for material and oxidation sensitivity
- Observable symptoms
- Free-versus-chucked shape differences, chucking failures or handling-crack risk caused by warpage
- Engineering decision
- Use supported shape measurements to compare thermal conditioning, chucking and downstream acceptance windows
Paths to assess first
Paths serve different purposes and can be combined01
Free and chucked wafer-shape measurementCompare free and chucked shapes at matched temperatures and references without mixing measurement states.
First02
Thermal-conditioning and support controlsCompare support, vacuum and conditioning histories; if thermal conditioning is used, check material-temperature and oxidation limits.
First03
Transfer and downstream acceptance windowsMatch measured shape and recovery time to downstream chuck/transfer windows to establish loading conditions.
