Fascinating video of how the original NeXT Cube's circuit board was made. It's actually a fairly good explanation of how SMT manufacturing is still done today. It is a little different (and much faster) but all the basics are there. What's so interesting to me is how far ahead of their time these manufacturing engineers were. They had 3-dimensional solder paste inspection in the 80's. That's amazing. 3D SPI has mostly been considered a modern technology. The NeXT engineers were truly ahead of their time. I would love to talk to whomever was responsible for this assembly line someday.
