UCC21732QDWRQ1 质量问题
是板卡FCT测试出现的问题,异常表现是 板卡输出电压异常。
ICT未覆盖这个点位。ICT测试平台EDS点检合格。
板卡FCT测试不良,交叉定位UCC21732QDWRQ1 READY脚位可输出电压异常。
我们有三台机器因为这颗芯片出现故障报废
请帮确认这颗料为什么会失效呢?
请给出失效原因报告,谢谢

Hi Qiulin,
Our team is based in US and can't respond in Chinese. If needed, and you have a TI engineer assigned to your account, please ask them to reach out to us for further discussion.
If you want to request the FIT rate report, you can do so here https://www.ti.com/product/UCC21732-Q1#all, where it says "Request more information."
Hope that helps!
Thanks,
Vivian
