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.
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.
Yuyue provides three-year after-sales support starting from the customer's acceptance date. For after-sales assistance, contact us through the email or WhatsApp listed on this website.
