    This was the first time I got a solder stencil from PCBWay. I am very satisfied by it. Tiny features were cut perfectly. See the picture for how the solder paste was deposited.

    Amazing quality and precision. I was able to assemble them very quickly to replace the 3D printed prototype. Also great communication with the team throughout the entire production process.
    Another high quality board from PCBWay. I ordered 0.8mm lead free and got it for a great price.
    Nice work. This board will be used in a logic trainer for a class I am teaching.
