Topic: What is the most expensive board you ever smoked? (Read 7278 times) previous topic - next topic


@ Grumpy Mike  " Only blew two parts but one was a BGA device. "

then you find out how good you are with a solder sucker and wick ?

As the solder points are underneath on a BGA packaged device, a solder sucker and wick would not be of any use.



"a solder sucker and wick would not be of any use."

Just my attempt at humour :-)

hot air and a good tap against the desk would fix that (hehe)


EPROM and system board in an old Telxon data collection terminal. We connected it to a DEC mini/mainframe (1989-ish) with RS232. One of the pins was high voltage from the DEC and smoked the entire Telxon unit. Left a black mark on the DEC case where the unit was sitting. When we were connecting it I was joking around saying "if you guys have a fire extinguisher around you might want it close by".....

Last time I used that joke.


I didn't do this, but I worked for a while building CNC plasma cutting machines. The plasma power supplies came in and we were supposed to check the voltage settings. One of the supervisors was setting a new set of plasma supplies up and hooked a supply that was wired for 220 to 440. It didn't last very long...


I once flashed an $1,500 motherboard back in 2000.. although not smoked, not turning on either lol


Back in the BA  ( before Arduino ) days,  I made a prototype washing machine timer with about 6 CMOS chips, to replace the clockwork one that was packing up in a popular machine.
My partnet waited for me to finish, as he had to drive 1000 Km to the factory for them to test it.
After I had it working I sealed it in white silicone so they couldnt copy it.
I didnt let it set enough I think, and when I did a final test, the silicone lit up with a brief white flash.
I built up another, and my partner drove through the night to get it there.
They approved it and we were busy with the megabucks agreement over 3 years, when they went bust :-(
