我们发现近期来料的20Kpcs MSP430G2955IRHA40R中有的料盘标签上的湿敏等级(MSL)不一致,有的为"3",有的为“2”,请问这个情况正常吗?TI官网查到的MSP430G2955IRHA40R湿敏等级为“3”,意思是这颗料无论产地无论Date Code湿敏等级都应该是“3”呢,还是说湿敏等级不低于“3”,可能会因产地和生产时间不一致?

以下是我核实后的回复
The different MSL level are correct. While the MSL for material from Malaysia is 3, the MSL for material from China is MSL 2.
The device was originally build in Malaysia only and later on also in China. During re-qualification for the A/T site in China, the device was passing MSL 2.
出现这样的情况是正常的,请您转告客户,谢谢
