Flex-rigid PCB | 24 June, 2020

Dear experts,

We are in stage to fix lapse or hold time between pre-bake to reflow process ( SMT ) for flex-rigid PCB, usually for flex pcb , we need to assemble as early as possible once after baking & if not , we can store in humidifier up to some hours before SMT assembly , so my question is that how long time we can hold the baked board before start of SMT assembly & again what is recommended duration between bottom side & Top side assembly for FLEX-RIGID POLIMER PCB .. As of now , we planning for 8 hours after pre-bake to reflow , is this fine ?? , please support as early as possible.

Thanks Prem Process Engineering Chennai,INDIA
