Reliable Volume • Controlled Cost • Low Warranty Risk
Strategic & Foundational

Clear Tooling & NRE Strategy
Assess tooling options—pilot fixtures, bridge tooling, production tooling—and amortize NRE to balance risk and unit cost at expected volumes.

Supplier & Process Qualification
Supplier audits, capability studies, PPAP/FAI coordination and build plans to ensure suppliers meet throughput and quality targets.

Supply Chain & Logistics
Packaging engineering, DDP fulfillment, VMI/JIT programs and customs/duty optimization to reduce lead times and inventory cost.
Five Stages of a Successful Ramp
Pilot & Proof
Low-volume pilot to validate process and assembly flows before heavy NRE.Tooling & Jigs
Plan and build production tooling and fixtures aligned to target cycle times and tolerances.Process Qualification
Confirm supplier readiness through PPAP/FAI audits and SPC/Cpk studies, establishing rigorous process windows for all critical-to-quality (CTQ) parameters.Scale Operations
Volume ramp with VMI/JIT, line balancing, and takt-time optimization to meet demand consistent with capacity.Continuous Improvement
Ongoing yield optimization, change control, warranty root cause closure, and lifecycle cost reduction.Capability-Focused

First pass and overall yield trends during ramp
Cpk (CTQs)
Process capability on critical dimensions and outputs
Throughput
Parts per hour and takt adherence
On-time Delivery
Supplier fill rate and DDP arrival performance
| Metric | Target | Action if off-target |
|---|---|---|
| First Pass Yield | > 95% | Root cause & containment, immediate process correction |
| Cpk (CTQ) | > 1.33 (1.67 preferred) | Process stabilization, tooling correction, tolerance evaluation |
| On-time Delivery | > 98% DDP | Supply rebalancing, expedite lanes, alternate sourcing |
Continuous Improvement & Post‑SOP Support

Warranty & Field Reliability
We run warranty analytics and closed-loop failure analysis to reduce root causes, track returns by SKU and supplier, and implement corrective actions with verification in production.

Lifecycle Cost Management
Review total landed cost periodically: duty, freight, packaging, warranty, rework and obsolescence to seek additional cost reduction opportunities.
Case Study — Scaling a Power Module Program
We supported a power module program through a six-month ramp from pilot to 50k units/year. Activities included tooling consolidation, supplier second-sourcing, establishing SPC dashboards, packaging redesign (reduced damage 67%), and a VMI program with Dallas warehouse stocking. Outcome: achieved target output with Cpk > 1.67 on CTQs and reduced time-to-ship by 40%.
