So instead of the IR thermometer you simply attached a sensor to the chip and you didn't even reached the recommended 230°C. And yet still success!?
, do you think it's a common thing to be (self-)authorized to use the "walk as an Egyptian" thingy?
Guess i will stop this stupid search for the right equipment and go with what's available in the store i buy all my tools.
Sure, you need a less German and more Latin approach
, after all the stupid thingies were probably assembled by people (not their fault) that don't even know the difference between °F and °C, and there is "tolerance" and "deviation", what precision do you expect out of a thermo couple given for free with a 20 or 25 € multimeter?
According to it my body temperature (when holding the thermo couple between my fingers) was 30 to 32 °C, and since I am still alive
a +- 5 degrees error it's probable. Is this fixed/linear or proportional?
PS: What went wrong with the other two?
They were dead and remained dead after the "treatment".
Either the problem was not related to a bad soldering or the procedure was wrong.
Or, since at the time I did have the hot air gun but not the thermo couple + multimeter I simply heated them a tad too much.
But I have no idea how to troubleshoot the hardware of an electronic board if not checking with a ohmmeter the continuity of the (few) tracks that you can actually test or visually inspect the board and maybe see if a capacitor "popped out", so it is possible that the problem could be easily solved by a "real" technician, with the right knowledge and possibly the right tools.
Though the actual base is too meager to draw any conclusion, of the first three attempts (without the temp control) one was successful.
Of the two attempts (with temp control) two were successful.
On the other hand, in my time
, I fixed more desktop motherboards than I can remember that simply had the 0.02 €/apiece keyboard fuse interrupted and were thrown away as "not repairable" by the actual (self-defined) "technicians".
