Identify: 2 chips visible; CPU model clearly readable (not covered).

  • No ball-count discount
  • Highest resale value
  • eMCP (eMMC) / uMCP (UFS)
Type 2
Cover Board (PoP)
30–100% depends on ball count

Structure: RAM stacked on top of CPU (PoP); storage chip standalone beside it.

Identify: 2 chips visible; CPU completely covered by RAM chip — CPU model NOT readable.

  • Regular, ≤64GB: 30%
  • Regular, ≥128GB: 50%
Type 3
Three-Chip Board

Quick Identification Guide

→ Three-Chip Board

2 chips + CPU model readable

→ Top Config Board

2 chips + CPU covered

→ Cover Board (PoP)

Non-Tier-1 Flash Memory — 50% Discount

Boards using non-tier-1 original flash chips (including Longsys and other minor/unbranded manufacturers) are settled at 50% of the standard price for the same capacity. Judged by chip silkscreen brand, verified by warehouse teardown.

Stacking rule: If a board qualifies for multiple discounts simultaneously (e.g. cover board + non-tier-1 flash), only the lowest discount applies — discounts do not stack.

Storage Types We Accept

EMCP

Embedded Multi-Chip Package. 221-ball and 254-ball configurations. RAM + ROM combined in one chip. Most common in mid-range devices.

UMCP

Universal Flash Storage Multi-Chip Package. 254-ball and 297-ball. Higher performance than EMCP, found in newer mid-to-high-end devices.

UFS / eMMC

Standalone UFS (153-ball) and eMMC (162-ball) memory chips as part of complete boards. We accept 32GB to 1TB capacities. Individual loose chips are NOT purchased.

Packing Requirements

  • Use anti-static bags for all boards and chips

  • Weigh with a gram-precision scale and photograph the reading
  • Use thick 5-layer cartons with foam filling; transparent tape for seams

Cover Board Special Handling

Cover boards (especially ≥128GB) must be individually wrapped in bubble wrap — no stacking or compression. Photograph the intact cover surface of every board before shipping. Without photos, cover damage claims will not be accepted.

Anti-tamper: Draw continuous cross-seam marks with a thick marker across all tape seams (half on tape, half on carton) and date them. Or use numbered tamper-evident seals. We verify marks at every transit node.
