    9:45 Oh no, all that effort, and the paste alignment is off by half the pin-pitch, and the paste has messily smeared across multiple pads, shorting them all together.
    I sincerely hope that this device can do better quality than that.
    (and before some says this quality would be "ok", we do not just rely on the solder's surface-tension to compensate for sloppy paste printing as that leads to high board-failure rates in production)

      Hi Nicholas. This stencil foil in the video has very little, and thin pad slots, particularly those that match with the processor chip. And yes, we can detect issues of alignment (that you talk about in your comment) due to the amplification of the images that we made with a manual electronic magnifier. Even so, we obtained not so bad results due to the capillary phenomenon in the melting solder paste that, around some limits, can compensate for these tiny misalignments sliding to the correct position during soldering process in the oven.
      Note that this project was made entirely in my home (except few parts that were made in a metal lathe shop). And I never ever made nothing similar before. My friend (the electronic engineer that regularly uses this contraption and the owner) is satisfied with the results, even in more detailed and complex projects such as computer PCB motherboards. I have another video (the first video about this contraption) where I explain a few more things about the exact same project (maybe you already viewed it): ruclips.net/video/-FIDfDakW5I/видео.html

      Hi Sandeep. Great. I'm glad you enjoyed my project. Everyone can make this project at home in a very small budget because is possible to obtain all de parts. Some parts are available, in STL format, for free, in the thingiverse for download (you can find the matching links in the description) and other parts, like the aluminium profile, for example, have the provider address indicated in the drawings plans (please look for the matching links in the description too for downloading all the drawing plans of this project). At your disposal. Regards.
