That sounds like a terrible idea unless you like planned obsolescence. I imagine those boards will have a very short lifespan.

They’re still encased in polymer. “Soluboard printed circuit boards need to be immersed in 90°C water (close to boiling point) for 30 minutes for the product to delaminate”, according to the CEO. I don’t imagine it will just melt/degrade slowly in a very short time span simply because of environmental heat and humidity.
