BLNKK's current understanding
Please check the details- Structure / bonding interface
- Copper-clip bondline above the power die
- Observation stage
- After clip attachment and during reliability stress
- Phenomenon to localize
- Clip-attachment voids, displacement, or interface cracks
- Engineering decision
- Localize the upper clip bond region to plan comparisons of attachment material, thickness, and clamping processes.
- Sample evidence still required
- How is the anomaly correlated with the die and leadframe ends of the clip above the die?
Paths to assess first
Paths serve different purposes and can be combined01
Upper bond location and stageSeparate the two endpoints, upper and lower bondlines, and defect timing.
First02
Clip material / thickness and attachmentCheck actual materials, metallization, bondline thickness, and attachment histories.
First03
Clamping and pre- / post-stress comparisonsHold support and test contacts constant; correlate the upper bond before and after stress.
FirstCurrent candidate solutions
Sample suitability still needs confirmationMethod review for upper bond locations and stagesBLNKK engineering research summary · Can help answer: Separate the two endpoints, upper and lower bondlines, and defect timing.
→Clip-attachment or clamping / stress comparisonsBLNKK engineering research summary · Can help answer: When inputs are complete for either clip material / thickness and attachment or clamping and pre- / post-stress comparisons, prepare that independent comparison first. The other retains its unconfirmed / excluded status.
→Joint review of clip attachment and clamping / stressBLNKK engineering research summary · Can help answer: Clip material / thickness and attachment and clamping and pre- / post-stress comparisons must both be comparable before discussing variables and tradeoffs under shared conditions.
