Three things to check first

Illustrative ic inventory inventory preparation — Match the complete part number, lot, quantity and packaging photos to each list entry.
Illustrative image, not a customer case photograph.

Full Part Numbers Are More Important Than Abbreviations

Retain known fields such as brand, part number suffix, package, and temperature grade. Do not replace the full part number with series names such as “STM32” or “power IC” alone.

整批回收与零散处理的对比

对比维度	整批回收（华芯购）	零散/档口处理
对接对象	工厂/企业主体，对公流程	个人或档口，现金私下为主
覆盖范围	整厂打包，多品类一次性对接	单品少量，多料号需分批
估价口径	按真实状态与市场行情，分组评估	口头报价，口径不透明
结算方式	对公账户结算，凭证留痕	现金/私下转账，留痕少
保密与合规	可签保密协议（NDA），合同约定	一般无书面保密
服务响应	工作日提交资料后当日报价，可全国上门	视档口现货情况，无上门能力

六类常见呆滞物料的处置口径

物料类别	常见形态	评估关注点	处置方式
IC / 主控	QFP/BGA/SOP 等封装	品牌型号、丝印、年份、库存环境	可流通料整批回收
存储类	FLASH/NAND/NOR/eMMC/DDR	容量、速率、批次、通电状态	按型号与状态分组评估
被动件	阻容感、晶振、磁珠	封装精度、料盘完整度	整盘/整卷打包
连接器	排针/座子/端子	规格、针数、表面处理	整批回收
功率器件	IGBT/MOSFET/二极管	耐压、电流、批次、封装	分组评估后整批对接
PCB 板卡/废料	板卡、边角料、电子废料	贵金属含量、板卡形态	按电子废料口径处置

Record Batches and Conditions Separately

List different date codes, batches, opened/unopened status, and quantities of the same part number separately. Label photos should correspond to list line numbers.

Discontinuation Does Not Necessarily Mean Appreciation

Whether it can circulate should be determined based on specific demand, alternative parts, traceability documentation, and physical condition. Lifecycle status should be verified against original manufacturer documentation.

Prepare inventory information that can be checked

MCUs, analog chips, logic devices, and discontinued ICs are verified by full part number. A preliminary review of submitted information and a final physical inspection are separate steps.

Manufacturer, full part number, quantity and count date
Lot / date code, packaging and opened status
Location, list version and representative label photos
Known issues and any confidentiality requirements

From information to handover

Prepare the list

Separate part numbers, quantities, lots and condition.

Clarify the scope

Match labels and photos to the review and inspection needs.

Agree the terms

Confirm price, logistics, discrepancies and settlement.

Document handover

Keep the agreed list and receiving records.

Before sharing sensitive information, discuss confidentiality scope, access, image use and retention. Initial valuation does not require unrelated project design files.
