- I've unintentionally set up a race between DHL and UPS They both have their warehouses right next to each other, both orders had their import taxes paid at the same time yesterday. Any bets on who will deliver first?
- Really excited to share this one - I arranged the PCB factory tour in China because I ordered the first production batch of Soleil boards there. This clip shows me unboxing the boards in the shipping room of the factory. They turned out absolutely great, really impressed with the quality
- Okay this was a really cool machine that I hadn't seen before. For certain through hole components, there is a machine which will dip the through hole legs into a small well of solder. It's better in some cases because it doesn't require tooling to create a mask for wave soldering
- This one is called wave soldering, and it is used to solder through hole components (which have "legs" that poke through the PCB) Basically, the PCB is loaded on a conveyor and slowly moves over a bath of melted solder. The legs drag through the liquid metal, and get soldered to exposed copper pads
- New clip from my factory tour of a PCB assembly shop in China this past week - showing a pick and place (PNP) machine. The toolhead on this machine has multiple vacuum nozzles which pick up the tiny components, move them to the correct spot on the PCB, then place and release them
