BLNKK's current understanding
Please check the details- Structure / bonding interface
- Power-module wire-bond joints and heels
- Observation stage
- After power cycling or mechanical fatigue
- Phenomenon to localize
- Wire-bond resistance drift, lift-off, or heel cracks
- Engineering decision
- Use wire-bond locations and electrical / fracture-surface evidence to plan comparisons of bonding windows and stress controls.
- Sample evidence still required
- How is the wire-bond electrical path correlated with feet / heels and normal joints?
Paths to assess first
Paths serve different purposes and can be combined01
Wire-bond location and fracture-surface reviewPreserve the original condition and correlate wire feet with heels.
First02
Bonding and local-load comparisonsHold wire material and geometry constant when comparing actual bonding conditions and local loads.
First03
Mechanical-mode and load comparisonsConfirm tools and destructive-test deliverables; distinguish single-test modes from cyclic loading.
FirstCurrent candidate solutions
Sample suitability still needs confirmationWire pull / shear configuration and fracture-mode comparisonNordson TEST & INSPECTION · Can help answer: The manufacturer lists wire pull / shear equipment and fracture-observation capabilities. First ask about this wire diameter, tool position, fixtures, and destructive-test deliverables; interpret these separately from cyclic loading.

→Preparation of bonding-load or mechanical-mode comparisonsBLNKK engineering research summary · Can help answer: When inputs are complete for either bonding and local-load comparisons or mechanical-mode and load comparisons, prepare that independent comparison first. The other retains its unconfirmed / excluded status.
