How big is the residual-value gap between domestic-substitution ICs and imported ICs in recycling?

It depends on certification tier and part-number liquidity. For MCUs, an imported AEC-Q100-qualified part (e.g., STM32F407 series) can carry 5-8× the residual value of an equivalent consumer-grade domestic part after refurbishment. A domestic substitute that has not yet entered the end-customer's BOM may have limited liquidity even with intact pins, typically clearing at only 40%-60% of the imported equivalent. The key variable is "can it actually sell?" rather than "what is the part worth on paper?"

What is the fundamental difference between MLCC recycling and IC recycling in terms of processing?

IC recycling is function-level verification: programmer read-out, pin continuity, key parameter measurement (Vth, Idd, frequency), and for automotive-grade parts, lot-number and certification-marking verification. MLCC recycling is electrical-parameter screening: LCR meter for capacitance deviation (±10% = Grade A), voltage-withstand test (1.5× rated voltage, 60s hold, no breakdown), ESR check, then re-taping. ICs are "tested one by one for life"; MLCCs are "batch-screened for parameters." The equipment investment and labour model are fundamentally different.

How do recyclers price fab edge wafers vs. OSAT rejects?

Two different logic chains. Fab edge wafers (edge dies, test scraps) are priced on "material residual + usable yield": if die integrity >80% and the part number has secondary-market circulation, pricing at 15%-30% of new-part value is viable; if it is a trial-production wafer or a part number with no secondary market, it is disposed at silicon material value (~CNY 100-220/wafer). OSAT rejects (pin oxidation, hermeticity failure) must pass visual + functional screening first: passing units go out at Grade-B refurbishment price (30%-50% of new), failing units go to material-residual channel. The critical step is verifying part-number liquidity before quoting.

Which categories offer the highest recycling margin in H2 2026? Is it still too late to enter?

Three areas currently concentrate the most profit: ① Automotive MCU / PMIC (AEC-Q100 certified, OEM lead-time instability, repair-market刚需); ② DDR5 / NAND storage (consumer iteration ~15% YoY, high price-cycle volatility, clear timing windows); ③ Special-spec MLCC (X7R / Y5V small-batch SKUs discontinued by OEMs, secondary market in sustained shortage). Entering now is still viable, but the window is narrowing—destocking completion will trigger concentrated stagnant-inventory liquidation, making Q3-Q4 the golden buy-in period, with potential price softening by end of Q4 as supply hits the market. Priority: lock in part numbers with proven secondary-market circulation; avoid accumulating domestic trial-production wafers with no downstream channel.

IGBT功率模块回收和普通芯片回收有什么不一样？

两类差异：一是形态——IGBT模块是大功率封装，内部是IGBT芯片+FRD续流二极管+铜基板DBC+键合铝线，不是单颗小封装，测试靠万用表二极管档与双脉冲测试台，而不是芯片测试座；二是渠道——普通芯片流向维修与翻新市场，IGBT模块流向功率模块翻新、电驱维修与变频器维修渠道，炸管件按废料铜基板计价。两者混料报价会损失大量利润。

IGBT功率模块回收价大概多少？

2026年参考区间（好模块）：车规英飞凌HybridPACK Drive FS820R08A6P2B约120-220元/块、FS400R07A1E3约60-110元；工业模块FF600R17ME4约80-150元、FF400R12KT4约50-100元；三菱CM400DY-24A约60-110元、CM600DY-24A约90-160元；单管IGBT（TO-247）IKW75N60T约3-6元/颗；国产同规格模块按英飞凌6-7折计价；炸管件5-15元/块按废料铜基板回收。

怎么判断IGBT模块是好的还是炸管的？

三步：一看外观——烧痕、外壳鼓包爆裂、引脚发黑的直接废料档；二用万用表二极管档测FRD续流二极管正反向压降，再测栅极-发射极，压降异常或开路短路的降档；三上双脉冲测试台实测开关特性，能正常开关、无拖尾的按好模块价，带测试记录的好模块可溢价15-25%。拆解时避免撬伤DBC基板与键合线，模块完整度直接决定价格。

国产IGBT模块和英飞凌/三菱的回收价差多少？

同规格国产模块（斯达GD系列、时代电气、士兰微、宏微）按英飞凌的6-7折计价，好批次成色完好的甚至更高。2026年国产IGBT回收量已占三成以上且持续上升：国产化率提升意味着供给更充足、价格更透明，出货渠道也更稳定——车规模块里HybridPACK Drive仍是流通量最大的单品，但国产模块是增长最快的档位。

2026 H2 Chip Recycling "Part-Number Liquidity" Play: Domestic Substitution Deep Waters × Inventory Residual-Value Pricing × Slow-Moving Flow Tracking

Destocking Ends, "Scrap Thinking" Retires

By H2 2026, the global semiconductor destocking cycle is drawing to a close. The blanket "chip shortage" narrative of the past two years is giving way to a far more granular structural split: leading-edge nodes (5 nm / 3 nm) and automotive-grade ICs remain on unstable lead times, while 28 nm and above mature-node capacity is visibly oversupplied. Domestic fabs, driven by accelerated substitution, continue to ramp volume—yield-ramp wafers, engineering samples, and OSAT rejects are flooding the secondary market. Meanwhile, end-manufacturers who hedged supply-chain risk by building dual-track (imported + domestic) safety stock are now facing concentrated liquidation pressure.

This contradiction—high-end tight, low-end glut, mid-band stagnant—is rewriting the pricing logic of the recycling industry. Recyclers who once quoted by "scrap tonnage" or "pulled-part average" must now adopt an inventory residual-value management lens. The same MCU package can carry 5–8× the residual value of a consumer-grade equivalent if it carries AEC-Q100 certification and an active secondary-market part number; conversely, a domestic yield-ramp trial wafer with intact pins may have near-zero liquidity.

The Core Variable: "Market Liquidity" of Domestic Part Numbers

As domestic substitution enters its deep-water phase in 2026, domestic design houses across the SMIC / Hua Hong / JCET ecosystem are spinning up record wafer starts, yet many part numbers have not yet established stable secondary-market channels. The critical question for recyclers is no longer "do we buy it?" but "can this part number actually sell, to whom, and at what clearing price?"

Part-number liquidity hinges on three dimensions:

Certification equivalence: whether the domestic part number has been qualified into the end-customer's BOM as a drop-in substitute (e.g., a domestic MCU mapped to an STM32F4xx series part with automotive or industrial-grade sign-off);
Demand-side fit: actual purchase frequency and lot size from repair shops, EMS providers, and research labs;
Supply-side scarcity: whether the OEM has EOL'd or retooled the part, and whether distributor channels still hold stock—discontinued part numbers command a significant premium.

Tracking Slow-Moving & Substitution Flow: Where the Premium Lives

From Q3 2026 onward, a clear pattern emerges in the flow of substitution and slow-moving inventory: OEMs with excess mature-node capacity are dumping unencapsulated wafers and aged devices at steep discounts; OSAT rejects (pin oxidation, hermeticity failures) are routed to non-critical equipment and teaching/research channels after inspection and sorting; and the highest-value recycling—automotive MCU, DDR5 / NAND, high-capacitance MLCC (X7R / Y5V special specs)—concentrates in repair-market and EMS replenishment demand.

A recycler who passively waits for inbound lots will only capture "scrap-tier" pricing. One who pre-builds a domestic part-number database, links information flows with OEMs and Tier-1 distributors, and tracks substitution-switching windows and slow-moving liquidation cadence can capture excess returns in volatile price cycles.

Category Residual-Value Matrix & Processing Paths

Category	Residual-Value Driver	Core Processing Requirement	Target Downstream	Liquidity Rating
Automotive MCU / PMIC	AEC-Q100 cert, high replacement cost, OEM lead-time instability	Functional test + pin/encapsulation grading + lot traceability	OEM repair, industrial control, EMS replenishment	★★★★★
DRAM / NAND (DDR5 / NAND)	High price-cycle volatility, fast consumer iteration (~15% YoY growth)	R/W test + bad-block rate + capacity/speed grading	Repair market, embedded dev, used OEM	★★★★☆
MLCC (X7R / Y5V special)	5G / NEV / AI-server demand, OEM EOL of small-batch SKUs	Capacitance / voltage screening + re-taping + ESD protection	EMS, research labs, small-batch lines	★★★★☆
IGBT / MOSFET (SiC)	NEV demand pull, domestic yield-ramp waste stream	Voltage / Vth test + thermal resistance + binning	NEV repair, industrial PSU, education	★★★☆☆
Consumer SoC / low-end logic	Thin margin, abundant substitution	Batch sort, material-residual disposal	Scrap extraction, teaching kits	★★☆☆☆

From "Scrap Buyer" to "Resource Balancer": H2 2026 Priorities

Three actions rank highest for recyclers in H2 2026:

Build the database: map domestic IC part numbers (MCU, memory, MLCC, power) with certification status, OEM lead time, and secondary-market activity—maintain a dynamic "part-number liquidity map";
Lock the source: establish direct-supply agreements with fabs (edge wafers / test scraps), OSAT (rejects / encapsulation defects), and OEMs (stagnant / tail-end stock) to secure stable inbound and bypass middleman markup;
Time the window: monitor OEM EOL notices, distributor stock-out signals, and end-customer BOM-switching windows—complete buy-in and redistribution within the 2–4 week "substitution gap" before spot supply normalises.

Structural chip shortage and domestic substitution are converging. The recycling market is no longer a "leftover" business—it is an indispensable strategic replenishment link in the semiconductor supply chain. Whoever masters part-number liquidity management will capture the premium in the next price cycle.
