Actually it's kinda the norm in most places. Subjects your active components to one less heat cycle.

Of Course you can. We have a customer specific board that has a stupid connector underneith, and we must manually glue this one onto it's postition before reflow on the secondary side first... And as you know, the customers is alwayw left... The funny thing is: Only chips on the primary side...But they are paying us for this stupid behaviour...

Ps. Don't tell anybody, but I have almost secretly been able to change the process in the oppossite way, our operators doesn't care but they think this is a bit of fun...We still doing the glueing process though. We all need some laughter once in a while. Ds.
