As a novice at soldering, I now have an opinion about single-sided vs. double-sided breadboards (self.electronics)

Me a few days ago, shopping on Amazon: "All the component and jumper wire leads are going to be on the bottom anyway; why shouldn't I get a pack of single-sided breadboards for $6.25 instead of double-sided ones for $10?"

Me today, after having lifted three pads off the damn board in 10 minutes: "Oh, that's why."

Get the double-sided breadboards; they're worth it.

The solder joints will be a lot stronger too. The solder will flow through the plated through hole and create a strong mechanical connection.

The pads shouldn't be lifting off the single sided boards though. Either the boards are crap quality or you're overheating the pads.

Either the boards are crap quality or you're overheating the pads.

Or both, probably!

Yeah I've only seen lifted pads when I'm desoldering a huge component, or on the absolute cheapest board. I find that the white boards and orange boards always suck

Double sided perfboards way more often than not don't have plated vias. The vast majority are just etched from a 2 layer blank without any post processing.

You would have to solder specifically on both sides in order to increase the strength.

But yes pads lifting is almost exclusively from dumping way too much heat in it. Because there is no plated through hole, it also has ~1/4 of the thermal mass so it is easier to overheat and damage the adhesive.

I guess the stuff I buy is an extra tier above then, because I definitely only spring for the platted through-hole double sided boards. I've cut little sections of my supply to use in various projects.
