Hello.
Can you do double sided PCB soldering?
If so, how to do that?

Any challanges to solder large PCB's?
If so, what is best practice.


Regards

thanks for asking. Our lab advises: double sided PCB reflow soldering should be possible theoretically even if we haven't tried yet… this will be done as soon as possible.

An idea would be to use component glue -- first put the paste on the pads on the side with the smallest number of components and a drop of glue in between the pads, place the component, allow it to glue to the boards surface, then do a reflow soldering process. Then put the paste on the second side, the components and then solder again… Should work fine.

Regarding large PCBs, no special precautions are necessary; please give it a try and practice before you go for a real target.

Well, if your PCB doesn't have plated through holes, then you must set up short pieces of wire in each via hole & solder on both the sides of the PCB to make the top to base connections. Through the hole elements provide the relationship with their legs, you do not have to get worried about those.
