Key Circuit Nodes & Hardware Interconnect Points
Sensing and control
Review reference points, harness loads and isolation from power circuits.
Board power path
Check resistance, rise, joints and fault current for actual current sharing.
Dissimilar-metal transition
Define Cu-Al contact surfaces, cut edges, fastening and moisture protection.

Project Validation Plan & Records
The Challenge
High-voltage spacing, low-level sensing and vibration loads require separate validation.
Review Plan
Compare candidates under matched electrical, thermal and mechanical boundaries; define sample revision, sensing points, method and acceptance.
Validation Records to Collect
- ✓ Four-wire resistance, contact drop and sensing locations
- ✓ Ambient, load, cooling and steady-state temperature rise
- ✓ Assembly loads and function before/after applicable exposure
- ✓ Quotation, sample results, deviations and revision approval
Frequently Asked Questions
How should certification and quality records be checked?+
Check the valid document, legal entity, site, product scope and expiry. A quality-system certificate does not replace component or equipment safety approval.
What is needed for an RFQ and sample review?+
Provide drawing revision, electrical and assembly conditions, quantity and validation requirements. Agree review scope, samples and lead time for the project.
