It has been my experience that with round hole protobards, the pads tend to rip off easier under soldering heat and that they are harder to connect with solder bridges. In lieu of this, I would like to propose that you guys offer some protoboards with square pads instead of round ones.
An example of what I am talking about: apogeekits.com/eurocard_ecs1-2.htm
The boards from the link above are quite possibly the best protoboards I have ever used, and are pretty reasonably priced. If you guys could come up with a set of something like those in addition to the ones you have, that would be awesome!
Also, on the protoboard pages you have, you have a picture showing some different sized boards, but those sizes aren’t available in the store…is there a plan to release those sizes anytime?
