I’m trying to reflow my circuit boards I recieved. Test 1 failed, test 2 in the oven cooling after a two stage reflow attempt. More details to come, but suffice to say QFN packages suck for DIY. I always suspected this would be an issue. Lots of test reflows went great, it’s just the stencil doesn’t work for the QFN (or BGA of the Balun). As a result I’m delaying my post entitled “Launching a Product” which will outline the next stages.
