I used to work at a place that had a factory that made cryogenically-freezable circuit boards. I only had to visit from time to time... It was a crazy 1980s legacy place with ancient machines and weird vats of weird smelling chemicals all over the place for etching and finishing. No idea whether they were harmful or not, nobody seemed to need any PPE though....
