@foone lol better not talk about a company who sells emmbedded circuits for satellites, a friend checked two recently, boards where dirty as ***, covered in flux residue, lots of solder microballs hanging around (meaning they used too much solder paste and didn't follow their supplier's recommendations on solder masks) and bad solders making the board not functional without rework. Top space-grade shit, everything is fine 😅
If we find products this bad on aerospace devices, I am not surprised that it's even worse in IoT ...
