YUNGUI PCB Protoboard,3 Pack PCB Prototype Board Solderable Breadboard for DIY Electronics and Soldering kit(4” X 6”,Blue), 4 Inches X 6 Inches

Hey, it's hard to mess up something like this. It was a decent price for decent quality, and I was able to do my prototyping with it.

I spent forever trying to find a quality PCB for prototypes, and this board is way better than most, due to the trace layout, which has common traces which form little bus bars, instead of individual holes that are not tied together like most cheap circuit boards. This PCB is blue, it has a white grid pattern of 1/2" square grid lines on the top surface, but it looks really nice and high quality.

Sturdy boards with pre-linked solder strips to reduce solder-blob connections. Take a look at the solder pattern in the pictures for details. For my project, these boards are perfect, sped up the soldering and probably reduced errors. My boards were 5 7/8" x 3 7/8", had 55 numbered columns. Rows are not numbered. Pre-printed solder strips on back were appropriately placed for my project with single-row and double-row components.

They are as advertised. Well built, small but need to describe how printed circuit is organized. Good product.

Got these just in case. Working mostly with standard PCB but I feel I will need this at some point.

Pretty decent for the price. The pads will withstand a couple of desolder/resolder iterations and the board itself is good quality. Hole spacing is standard 0.1” (2.54mm)

I use these boards for home projects and they work great. No issues to speak of.

I think the trace layout on these are almost perfect for proto-typing. But I had nothing but problems soldering parts to these boards. Seems that the holes do not accept solder. To get it to work I used gobs of solder (no, the bigger the gob does not make a better job). So I hope the manufacturer goes to plated through-holes. Then these things would be almost perfect. On the plus side they are very rigid, strong, good sized, have plenty of holes, are in general (except for the hole solderability) they appear to be a superior product. Ignore me and see what you think of their solderability. Just what I found.

fait la job

Although I purchased these some time ago, I only now used one to build a small project. I found that there is no continuity on some lines on the board. I am not sure if this was present prior to the build or caused by the heat of soldering with a micro-solder tip. In either case, it required the use of jumpers on some lines.

Solder pads only on one side. Even with 50 years soldering experience, difficult to solder to. Wouldn't buy it again.
