您好！

       我购买的产品有些小问题，有些 不良品，想请求做个失效性分析，帮忙查找原因，但是被拒绝了，回复如下：

Comments from TI: TI has reviewed this request and determined that the problem description is not clear. Please update the problem description based on TI device functionality. Tell failure pins and corresponding failure signals/waveforms, comparing btw NG and GOOD. Also, please contact TI techncial engineer to review the application design.

我不太理解要求补充哪些资料，能帮我看一下吗？
