Last year my $2500 oven stopped working. I am not a tech guy but my good friend who is an electrical engineer taught me a few things. First I smelled the board and I smelled burnt plastic. Found a relay switch or something like that that was burnt. Its over 10 years old and they stopped making the circuit boards for it. i found one on ebay for around $600. So instead I brought it to my friends dad who works on electronics. Took him about 10 min to resolder one of the post back to the board and it was fixed. A 10 min resolder saved me from having to buy a brand new stove at around $2500 or to buy the $600 board on EBAY and hope it works!
He thinks the solder was bad and was arching causing the solder to slowly disappear over the years, to where it failed by melting completely.

So, an alloy of tin silver and copper " slowly disappear"d? NOT in this universe! Why do you only believe the fairy stories?

Why do you think spark plugs get "worn out" or light swtches stop working? Every time there is an electrical arc it strips the atoms away from the metal, creating light as it "burns", otherwise known as plasma. Yes, it disappears! Into the universe, as energy, maybe, I dont fucking know. Maybe it just transfers to another peice of metal somewhere else on the pin or the board. As far as I can see, it disappears, lol! That is what happened on the circuit board of my stove. There was not enough solder or it was not done properly and every time my oven kicked on, through the relay switch, it ate away at the solder, over a decade of use it finally arched large enough to separate the solder and the pin completely.
I am NOT that knowledgeable in this field, I am explaining it the best I can, someone else who knows more than I do about this can explain it better than I can. For instance, what happens after the arch and where does the metal go? I dont know. I do know that arching electricity does eat away at the metal.

Is that a Roman arch or a gothic arch? BTW as a registered instructor for IPC 610-c, I do understand the phisics of soldering and the chemistry. Yes my first degree was in chemistry, physics was part of my second degree, and I spent most of my working life as an engineer working in manufacture of electronic assemblies. That is why I get annoyed at ignorance of the depth displayed here.

Well, god damn, you could have just explained it better than I could have instead of just being a dick! WTF! I clearly did not have the time in my life to learn everything about this shit and I even said so in my comment, I was sharing a story. If there are gaps or flaws that you know about, then feel free to ADD to conversation instead of sitting on your high horse of knowledge doing nothing but mocking!
Soooo... what is YOUR take on what happened to my stove???

If the problem was permantly solved by resoldering a single joint then the most probable cause would be a badly formed / reflowed solder joint, these usually occour when the manufacturing is based on cheapness/speed and not quality.
A common problem found in a low skilled, under pressure workforce.
I will stick my neck out and say that PCB was not manufactured in Germany! Or any other civillized country.

Maybe if you are in Europe you can find good qaulity made products, I am in the USA, EVERYTHING is made in China!
Ok, so solder can NEVER be lost due to arcing, is that what you are telling me? If it is, hey what the fuck do I know, you claim to be the expert so I will agree until I hear otherwise. Reflowing, sounds good. The solder gave out after ten years of use, Badly formed seems like it would have given out first try, arcing producing the heat to shift the solder over time, sounds good!

i've dabled in electronics, ruined alot of stuff growing up, licked alot of 9v batteries and rode the lightning a few times.
a soldering joint, if done right. will continue to work hundreds of years after we die.
an arc is a short, the arc itself it does create heat but solder sticks to heat, it literally flows to it. if it was an arc, you would have probably been hearing some sort of clicking, sparking. you'd probably also be having issues with other things because of the arc is bypassing the resistance on the board, maybe popping resistors and capacitors.
