Hi Jie,Please be aware that some B364 flexes have expired at FATP site (Compal) so we need Compeq to do shelf life extension test and wetting balance test following J-STD-033 at your site.Compal will return some samples with below expired DC back to Compeq for the testing and please work with Compal on this testing (I have looped them in) and let us know if you need any help.
