If you have control of the solder alloy you're able to use on the product, you could run a lower temp solder on the second side and try to avoid the first side entering reflow.

I see that the connector has plastic alignment pins. Is there any reason you can squirt a drop hi-temp "Crazy" glue into each hole, after the bottom side assembly and before printing the top side?

Hello, The oven profil is not the solution! The only solution for the solder mount on the side is to put gel flux on the side of qfn and make a second travel in reflow . The flux remove oxyde from the copper that is not tinned and the solder is able

I guess the link you sent shows Top Side of the component. Send a picture of the bottom side - which the camera will see and I may be able to help.

Has anyone experienced issues with the Red-E-Set support system damaging components on double sided boards? How's the setup, its advertised as quick? Any issue with misprints using this support system?

You may have to use an adaptor board. A small board with one footprint on one side and the other on the other side. Do not assume that the pin outs of the two parts are the same. I have seen smaller parts with a different pin out than the bigger part

Hi SMTnet. It is possible to reflow BGA's 0.65 pitch with a convection oven that only have heating zones on one side (topside) or is it a must to have heating zones on both sides in the oven (top and botton). Regards Ole C. Denmark

Why is your customer controlling your process? You should be the expert on your processes. As long as the components that are on your second side would stay if they were processed as the first side this would be an acceptable solution to your issue

First of all, like I said before, I only worked on similar type of part. For this part, I would add at least 1 of 0603 size solder bead at each end (091845.jpg), 2 of 0402 size solder beads side by side would be even better.
