My guess would be that thermal cycling of the heat-sink has cracked the track on the PCB, and once it started to arc across the gap things would go downhill pretty fast. But that's a guess. Repair is not impossible. I had a similar PCB fire with an STMBL and managed to repair it. https://photos.app.goo.gl/76JSesUMGi65fFBPA I cleaned out the carbon, painted the bare FR4 with nail varnish and replaced the missing tracks with wires (some floating in air connected only to component pins). Then I ordered 50 replacements :-) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
