Quality & Condition of Refurbished Memory Components

Every part is reballed where needed, tested, burned in and lot-recorded at our Shenzhen manufacturing base, then shipped with the documents you ask for.

Process

1 Incoming inspectionVisual check under magnification. Markings and package are compared with manufacturer part-number data; mismatches are rejected.

2 ReballingAutomatic flux dispensing, solder-ball placement and ball inspection at ±0.05 mm, up to 3,000 devices per hour.

3 Reflow10-zone vacuum nitrogen reflow, oxygen ≤1,000 ppm, void rate ≤5%.

4 Electrical testDedicated DDR3, DDR4 and eMMC test machines check each device and bin out failures.

5 Burn-inSimultaneous burn-in of 128 DDR3, 128 DDR4 or 240 eMMC devices per machine.

6 Lot record & packingLot identifier linked to inspection and test data; ESD-safe, moisture-controlled packing.

Exact part number

We ship the number you ordered, or tell you before shipping if it is a near match.

Condition in writing

Every quote states New (unused), Surplus (unused stock) or Refurbished (previously used or reclaimed, reballed as needed and tested).

Tested before sale

Electrical test and burn-in on the equipment above; failed devices are never sold as good stock.

Traceable lots

A problem can be traced back to its lot, inspection and test records.
