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.
