The EMS scramble
Your customer in Querétaro needs 80,000 power IC units for the next automotive build. The Shenzhen EMS you’ve used for two years quotes 14 weeks instead of 4 — they’re allocated 95% on a Tier-1 automotive customer through Q3. You don’t have a second EMS qualified for this part because nobody finished the Suzhou backup onboarding 18 months ago. The single-source risk has been a yellow cell on a spreadsheet ever since. Now it’s a missed quarter.
