Very basic question: I have a small circuit board that has headers already soldered onto it. I want to solder these headers to a "protoboard" and then attach other components to the protoboard. However, when I do that the original circuit board is suspended above the protoboard about an eighth of an inch with no support except for the solder joints on the headers. This doesn't seem like a good idea but I'm not sure what to do about it. Is it typical to just leave the original circuit board suspended, assuming that the solder joints can take the very small amount of stress from the weight of the small circuit board? Or is it more typical to put something underneath the small circuit board to support it? But in that case, what's the best thing to use to do that? A picture of the best way to securely attach the small circuit board to the protoboard in this situation would be very helpful. Sorry for the very basic question, but I haven't done this very much. Thanks in advance for any suggestions.
