封装可靠性试验TCT经验分享 上图中,MSL3等级的TCT常用条件为B或者C,根据客户应用场景和客户系统级可靠性的标准来定,只要高于客户的系统级考核标准就行。至于cycle数,是根据寿命要求和工况来算。 按照封装形式,通常BGA用B,框架类C;LGA用TCB,cycle 500/700/1000都有;QFN功率器件一般都是TCC。 如果对自己公司的基板...

Intriguingly, NPHP1 also regulates resistance to apoptosis but not the cell cycle22. To ascertain whether NPHP1 expression is altered in the brains of Tctn3 KO mice, we collected brain tissues from E12.5 mice to examine the protein expression of NPHP1 in Tctn3 KO mice. Our results showed ...
