Quality you can evaluate

Clear arrival-inspection commitments.

Choose the part. Confirm the test requirements. Evaluate the sample in your own application.

These commitments refer only to customer arrival inspection of ordered chips, not module acceptance standards, bit error rates, measured historical statistics or lifetime failure rates. The sampling plan and acceptance criteria are confirmed for the ordered part.

Company roles and details →

How do original-marked used and refurbished chips differ?

Original-marked used chips retain their original markings. Refurbished or re-marked supply is disclosed with its actual identity and condition. Neither description means factory-new material; appearance alone does not establish electrical performance.

Read the condition checklist →

Is every unit tested before shipment?

Sampling inspections are carried out before shipment and during customer incoming acceptance. Contact Yuyue to confirm the applicable test items, sampling plan and acceptance criteria for your product and order. The two stages may use different test items, sample sizes and acceptance criteria. Sample results do not establish that every unit was tested or that an entire lot is defect-free. Sampling does not restrict after-sales support to the inspected units.
