Hi, Guy, please check the lamination of the PCB's; or the the BGA rework machine, some things like m/c levelling, and force placement head

We are looking at reflow soldering some Flexi-rigid pcbs. I have heard that IR reflow soldering can make the Polyimide "self heat" and cause de-lamination. Does anyone have any info.
