Component Sourcing & Supply Chain Support

Reliable PCB assembly depends on more than component availability. We review BOM requirements, sourcing channels, lead times, approved alternatives, and traceability before production begins.

BOM & Part-Number Review

Confirm manufacturer names, specifications, packaging, quantities, and acceptable alternatives.

Availability & Lead-Time Check

Identify long-lead, discontinued, or allocation-sensitive components before production.

Approved Alternative Coordination

Discuss substitute parts with customers before any component changes are made.

Traceability & Incoming Verification

Check supplier records, labels, packaging, quantities, and incoming material condition.

Component substitutions are not made without customer review and approval.
