I bought a slew of these for a large project full of small elements. The price and size are great as is the mounting hole but I am finding them very difficult to use because the traces described are only visible with a magnifying glass and they don’t seem to connect the 3 holes. Consequently I am having to bridge all connections which is slow and messy. Maybe mine are dysfunctional? Also 2 power rails that run all the way through would make this product more useful to me.
Hi, Sorry for the troubles. The connections should be there. We do sell a different protoboard that is not internally connected. If you do not have any internal traces, we may have made a mistake and sent you the wrong thing. If you have some internal traces, try setting the board so that the mounting hole is pointed up and away from you(like the second product picture), then the traces will go up and down and be connected 3 rows at a time.
I love these things. As with most prototyping boards, the conductive ring pads (I’m not sure what they’re called) will come off if they’re overheated.
If you’re having a hard time seeing the traces, try putting the board in front of a flashlight or a lamp or something.
