Recently, the boards for a small power converter arrived from PCBWay. This board house provides a fast and reliable service. In the following image you can get a own impression of the produced boards:
I especially like the wide range of solder mask colours you can choose from. They have green, red, yellow, blue, white, black, purple, matte black and matte green. Unlike some other manufacturers, the first six colours are produced at the same cost.
For me personally, it is a good choice for rough prototypes, where cost is the main factor. You get a fast and reliable service with a functional result.
