Looking for PC B boards?

Question: The PCB boards look like they would fit into some kind of card slot or socket because of the pads on the edge. Is that true? If so, where can I find them from China OEM PCB assembly supplier?

Answer: I just used it for soldering components on it. However, it is easy to cut and can be custom shaped to fit into any kind of platform. 

Because I build a lot of relatively simple projects (parts count, anyway) years ago, and I needed some small boards for prototyping. Up until now, I had to buy relatively expensive larger boards and cut them down. Now with the high development of technology, it is time for the change of the high quality steering parts oem in China too. These boards are great because they are small, cheap, and single-sided. You might think that the last item is a deficiency, but double-sided, plated-through holes take a PCB more solder. You also have to be careful with component mounting because the top side is live. If you have complex wiring you probably do need to have wires on both sides, but these are better for simple projects.

Too some extent, China metal stamping parts OEM is also good for us with relative cheap price.
