ElectroCookie Solderable Breadboard Large PCB Board for Electronics Projects Compatible for DIY Arduino Soldering Projects, Gold-Plated (3 Pack, Black)

These are excellent quality and replicate standard full-size breadboards almost exactly. Where they differ, they are actually an improvement, with the power rails being available at all 63 positions. I built Ben Eater's 6502 breadboard computer and then transferred it to these boards. I highly recommend them. A tip for the person who finds adjacent holes filling up with solder - use finer solder. That will allow you to control more easily how much you apply. Also, if you are using additional flux - don't. There's enough flux included in the solder for this particular through-hole purpose. Surface mount components are a different case but you won't be using them with these boards.

I was actually undecided between 4 or 5 stars for this one.Build quality is really good, and they can take the heat well when soldering.But for me, I find the terminal strips a bit too wide for my taste.If you look at the product pictures, you'll see the terminal strips are as wide as the power rails. This makes it easy to accidentally cover with solder adjacent holes on the same strip (see my picture).The previous solderable breadboards I used were Adafruit's Perma-Proto, where the strips are way narrower (maybe too much actually).Depending on your assembling method, it might not make any difference, but personally I tend to solder some things such as connectors, sockets, etc to set the desired layout then go ahead and do the actual wiring, which means once I go for the wiring step, I might need to use some wick to clear up any holes I accidently covered.If it's a small enough project, you'll probably put put everything on the board and solder all at once, so that won't make any difference, and the spilling the solder to the next hold in the strip might even make it easier.Still, from slightly more than 100 connections I soldered yesterday on my first step of new board, I had only 1 of those accidents, but a lot of close calls. :DThe upside is that I found that wider strips make it easier to get that satisfying pyramid shape when soldering (makes for a better connection).So far, that seems like the only niggle I have, and something to keep in mind.I'll probably keep buying them, since they are good value for the quality you get.
