An interesting article. I particularly liked the statement "There exists a sobering truth about today=92s electronic assemblies. 100% of today=92s consumer electronics are made without rosin flux (moisture resistance), use fluxes that do not =93require=94 cleaning (leaves contamination behind more readily), use solders that contain no lead (creates more difficult soldering processes), and use boards that contain no halides to prevent the board from burning if a shorting or corrosions event were to occur." Regarding the original posters problem - how about adding a crowbar circuit + fuse. Pretty easy to implement on any type of power supply.
