Returns and issue handling

Semiconductor prototype work is handled through RFQ, quote, inspection and aftersales tickets rather than instant consumer checkout returns.

Operational policy

Acceptance criteria, documentation, packaging state and inspection window are confirmed in the quote or purchase order.
Nonconformance, shipping damage or missing documentation should be raised with order references and photos where safe.
Do not send export-sensitive design files through public forms; use the agreed secure channel after MST review.
