When running some double sided reflow boards through the Heller oven, some of the caps/ res's are falling off the bottom side of the board. I understand if the parts are too heavy they wont stay in the molten solder, but these particular parts are no

Are the components that fall from the board solderable? Is the board solderable? Where is the solder for the components that fall from the board [eg, on the pads, on the component]?

Hello, As you know for the double side assembly PCBs, we normally first place the bottom side, then place top side after reflow soldering of bottom side. are there any other considerations for the sequence of reflow soldering ( bottoms side first, to

We run double sided surface mount boards through our Heller oven without any parts falling off the bottom side unless they are too big/heavy. The trick we use is to set the bottom side temperature in the final 3 heat zones 10C-20C lower than the top

I would like to have information about the processability of different packages. In particular I would like to known for which package I can use a double reflow for soldering. Best Regards

Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

By double reflow are you referring to double sided reflow? Or are you referring to reflowing twice? | I would like to have information about the processability of different packages. | In particular I would like to known for which package I can use

This site is dedicated to double sided reflow and solder balls. Wasssup?
