- Always reference your PO number and Amtech work order number in correspondence
- Put design changes in writing — verbal change authorizations are not accepted
- Send schedule changes as early as possible — rescheduling a build that has been kitted wastes material handling time
- If you receive an NCR (Non-Conformance Report), respond within 5 business days with disposition
- When requesting expedite, explain the business reason — it helps Amtech prioritize across customer needs
GOLDEN RULE: The earlier you communicate a problem or change, the cheaper it is for everyone. Surprises are expensive.
