….that 48 people were killed in 1980 when a space-launch rocket exploded whilst being fuelled at Plesetsk in the then Soviet Union.
The rocket used hydrogen peroxide as fuel, and the method of fuel filter assembly had changed from using lead solder to tin-based solder.
Fuck you, RoHS directive!
Hydrogen peroxide can decompose in the presence of some catalysts. This reaction can be violent. Lead doesn’t do it. Tin does.
So not only does it cause your Xbox to die and need the tea-towel treatment, it may blow you up also.
knew there was a reason why, in my computer-fixing workshop days, we used to use leaded solder as a kind of illicit prison-cigarettes currency.
Lead-free is the devil.
