Thank you both, it is not the good HLA design and this is why the deflection is needed to sit everything properly in the case. We did ask cust0mer(we are CM) to change it, I am just looking for a standard to support our claim.

Be careful of MSL level 4 or higher devices on the first side. if they sit out 3 days, they will need to be baked before second side reflow or you risk component damage.

Hi Russ, there�s something I don�t understand about the measures you took. I guess that TAL means time above liquidous and shortening of that time can result in bad dissolution of the protective Au-layer. The necessary time for the Au to mix with you
