HiLetgo 20pcs Solder Finished Prototype PCB for DIY 5x7cm Circuit Board Breadboard

Like I put this was a first time using these boards. All the others were put the part in and solder in place the traces were already done. This was for a motor controller project I need for the main project I'm working on.I did overheat a couple of the copper spots and they came off the board but didn't hurt the project any. This was basically watch, figure where components go, solder and cross fingers when powering up. Needless to say had a solder bridge and forgot to connect one side of a component. After that it works. Guess is not bad for winging it.Will be making two more later on as the main project grows with these boards.

Thank You!

They're a bit in the thin, flimsy side, but the holes work for most resistors and other soldering projects. I had trouble with random cracks as I was trying to cut these down to size, so I would use a rotary tool or a small jewelers hacksaw to cut these to shape.

Good for DIY projects

These smelled so bad I had to seal them up in a baggie and put them away upon opening them. I couldn’t tolerate having them on my bench - hopefully I can put them outside and they’ll air out before I go to use one.They feel exceptionally cheap, and given the smell, I would strongly caution against buying. I fully expect to have the copper traces lift if I try to reuse one (which I won’t given the smell and flimsy quality).However, if you know what you’re getting into and are looking for a cheap perfboard, this may be for you and I’m an outlier.Keep prototyping!

These don’t look like much but they are nice and sturdy and work well. I especially like that the rows/columns are labeled like a breadboard and broken into grids. One of my most annoying mistakes while trying to assemble a prototype is placing a component on the wrong spot.

The thing I like best about these boards is that they are cheap and adequate quality. Solder rework may result in losing a copper pad, so be careful. Second best thing is that they use an organic coating over the copper pads that prevents them from corroding, yet act as a flux during soldering. This coating is a replacement for tin coating that you see on the more expensive bread board products.

Pads don't stick. Inaccurate sizes, alignments, and etching. Should have read other reviews. Yeah, you get what you pay for, and I suppose some will say that I shouldn't complain about 20 boards for $7. Yet, I still feel cheated. If you need one board for a project and someone offers you 20, and you get 20 crappy boards, you've still lost. Stay away from these boards.
