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 |

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 Packaging and Storage Information
Opening time, moisture-barrier packaging, labels, and warehousing records can help determine the scope of the next verification step. Intact appearance alone cannot prove electrical performance or original authenticity.
Communicate Based on Current Conditions
Batch age does not correspond to a fixed discount ratio; the specific evaluation also depends on market demand, traceability, and physical verification. No general price-increase/decrease commitments are provided.
