Power wire-bond lift-off and heel fatigue

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.

Before you get started

What will I get from Navigator?

Explore technical paths and candidates related to an engineering problem. Compare intended uses, applicability and sources, identify missing information and key questions, and download an assessment preparation summary. These outputs help you prepare your next technical assessment. Applicability still requires samples, measurements and supplier confirmation.

When do I need to sign in?

You can browse engineering problems, suppliers and solutions, and compare solutions without signing in. Sign in to save cloud copies of cases, view account-linked inquiry history, claim a supplier company, propose updates or reply with supplier authorization. Supplier permissions also require a reviewed claim or an owner invitation.

How are solutions compiled? Are candidates recommendations?

The supplier catalog is compiled from public sources. Problem-specific candidates include context for the problem, structure and stage. A listing or candidate does not establish verified applicability, supplier endorsement or a purchasing recommendation. Read the sources and limitations together, then confirm your conditions with the supplier.
