A little oil on the dough, then the pizza sauce, then the toppings. Next place it in the reflow oven using a standard leaded reflow profile, might have to slow down the belt a bit. Should turn out a tasty pizza. ;-)

Yeo, These are possible rootcause of that defect and you can evaluate. 1. Orientation of the capacitor, maybe the cap is located behind big component. 2. Reflow profile, check the profile on that side. 3. Yes, check also the mounting force. Philip

We use a universal recipe for 90% of our products. But, I had to develop a temperature profile for each PCB to know that I was getting the correct temperature at the PCB. You may need to work a weekend or a couple of late nights to get the data. Go

Myu: Did you have to change your reflow profiles when you changed from 609 to 709? What ramp rate & time over liquidus are your profiles at?

Thanks Grant. I have Heller 1707 and it has built in thermal profiler. As a start up We won't be able to buy kic, but I have used in past and it is great.

That is what I was looking for. The profiles did not make much sense to me. We are getting alot of cold solder joints or bumpy solder joints.

Well that Genius did it on this BGA. It does have a heatsink and absorbs alot of heat. It just stinks because the BGA cost over 1000 and I really can not scrap a board. But that first profile does not look correct for this board with the BGA esp.
