Get ready for the Metro M4! The Adafruit Prototyping League is at it again, this time manufacturing our first test batch of Metro M4’s. We hand stencil each PCB using a laser cut jig and send the boards through the pick ‘n place one by one. After visual inspection they head into the reflow oven where the solder paste transforms into solid metal joints. Stay tuned for more.
Happy Manufacturing Monday from Adafruit!
