| Does anybody put QFP's on the backsides of boards? Can they be reflowed without falling off? Do you use adhesive? | I use a double sided reflow process all day, everyday. I've hung QFP240s with embedded heat sinks and they don't fall off. Yei

I'd like to add something about the ECD product. During a past work term (I'm a a co-op student) in an SMA plant, I worked extensively with the Super MOLE Gold in developing the reflow profiles for high-mix, low-volume production. I was 'married' t
