SOLUTION NAVIGATOREngineering conditions
For “Power wire-bond lift-off and heel fatigue”, add details that may change the assessment order and check the basis and limits of each candidate.
Engineering conditions
First correlate electrical drift with local wire-foot / heel evidence, then compare bonding records and actual thermal / mechanical loads. Overall thermal resistance and a single pull-force value cannot substitute for wire-bond fatigue modes. Unknowns remain unconfirmed. “Evaluable” means only that the method has complete inputs; it does not establish diagnosis or qualification.

Unconfirmed: Have the electrical path and physical defect been localized to a wire-bond joint or heel?; Are original / staged samples, decapsulation records, and foot / heel fracture-surface controls preserved?First obtain the location, history, or comparison baseline missing for this route.
Unconfirmed: Have the electrical path and physical defect been localized to a wire-bond joint or heel?; Are wire material / diameter, pad surfaces, loop / heel geometry, and actual bonding records comparable?; Are actual local current, thermal / mechanical loads, temperature-measurement timing, and package constraints comparable?First obtain the location, history, or comparison baseline missing for this route.

The order changes only with conditions you confirm. Public information cannot establish suitability for your actual samples.
After one round of comparisons, choose the next step based on actual observations.
Results only change the order of the next investigation; they do not modify condition answers, prove a root cause, or qualify a solution.
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.

Zeng et al. / Infineon author repository · First results of development of a lifetime model for transfer molded discrete power devices ↗The 2018 study concerns transfer-molded discrete devices; it does not qualify this power module. Do not transfer voltage thresholds, fitted coefficients, or cycling lifetimes. Bright SAM regions and overall voltage drift do not prove a single fracture mode.
Nordson TEST & INSPECTION · Bond Testing ↗Public equipment capabilities do not establish service acceptance for this wire diameter or package. Destructive pull / shear loads cannot directly substitute for power-cycling fatigue or sample acceptance.

Confirm with the supplier Confirm opening methods, available analyses, sampling and acceptance criteria, and how the report distinguishes original defects from preparation or test damage.The official page describes the three-layer finish and eliminating external solder plating during IC assembly.
Limit: Scope and limitations PPF neither measures fatigue nor repairs cracks. General reliability descriptions do not qualify every wire/finish pairing or establish mission life.

Confirm with the supplier Confirm head, bandwidth, spot/access, reference synchronization and sample feasibility, together with the separate bond-quality acceptance method.SIMULIA documents multi-solver fatigue analysis.
Limit: Scope and limitations Bulk-material database curves are not automatically valid for fine wires or bonds.

Confirm with the supplier Confirm wire/pad compatibility, tool and loop limitations, available process signals and the sample/reliability validation approach.Nippon Micrometal distinguishes EX grade features, but provides no qualification or fatigue-life result for your package/loop.
Limit: Scope and limitations Coatings and humidity/temperature positioning differ by grade. Qualification statements cannot cover the entire family or your assembly; changing wire does not repair existing lift or cracks. What to prepare BLNKK suggests preparing grades, diameters, pad metallurgy, loop drawings and bonding parameters.

Agree on loop, failure-location and actual-load comparisons, and clarify the scope of any qualification statement.The official page names these TANAKA ELECTRONICS products and power-device applications.

Confirm with the supplier Confirm grades, dimensions and bonding compatibility, and comparisons of failure modes and durability after thermal/current loading.The official lineup distinguishes TG loop types and TG-B/RB bumping wire, with qualitative series-specific features.
Limit: Scope and limitations Stable-loop or bump-height descriptions do not qualify the actual height distribution or fatigue life. Properties are not interchangeable across TG grades.

Confirm with the supplier Confirm the grade, ball/cut/bonding window and assessment of height consistency, interface strength and cyclic reliability.Official information lists wire pull, ball shear and die shear applications.
Limit: Scope and limitations A single strength test does not predict fatigue life. Tooling, speed and failure location affect comparability.

Confirm with the supplier Confirm sensors, tools, holders and current microscope configuration, and how to compare test conditions and failure modes together.Official specifications describe heads, monitoring and optional PiQC/non-destructive pull, not this module’s cycling qualification.
Limit: Scope and limitations Real-time monitoring establishes neither fatigue life nor detection of every defect. Wire/ribbon size is application-dependent; confirm actual PiQC/pull configuration. What to prepare BLNKK suggests preparing wire/dimensions, pad metallization/surface, loop and bonding settings, pull/shear results, fracture locations and cycling-load records. Confirm with the supplier Confirm model/head/tool/material compatibility and monitoring/pull options. Agree on actual-module strength, failure-mode and cycling trials, including alarm criteria.The official page separates ball, wedge, deep-access, heavy-wire/ribbon heads and pull/shear testing configurations.

Confirm with the supplier Confirm selected heads, tool/material compatibility, pad access, data export and required fatigue-validation arrangements.Current system and pull-test pages document wire/ribbon testing.
Limit: Scope and limitations Pull force depends on angle, tool contact and fracture location; it is not individual-interface stress. Static strength or one proof load does not establish fatigue life.

Confirm with the supplier Confirm sensor/tool, hook placement, speed, fixture and test mode. Agree on calibration, repeatability, fracture grading, comparison criteria and data export.The service page describes planning and project management; the October 2024 PEM FAQ gives package risks and an example flow.

FAQ sample counts and stress sequences are examples, and copper-wire capability does not establish qualification of every wire material. What to prepare BLNKK suggests preparing device/package and material changes, operating conditions, target requirements, previous tests and failures; wire-bond investigations also need wire materials, bonding metals and suspected locations. Confirm with the supplier Confirm the qualification plan, standard editions, representative sample quantities, stress/rejection criteria and handling/reporting of failures. Wire-bond work also needs agreement on decapsulation and pull/shear methods.Before assessment
