Comment on Let's play Spot the Cold Solder.
lazylion_ca@lemmy.ca 5 months agoThis is a circuit board from my slow cooker. It quit heating a week ago so I opened it up and found a broken wire. That was easily fixed.
I figured while I had it apart I should look at the display board and see if I can fix the missing segments. I resoldered the one pin but nothing changed.
Unfortunately my eyes arent what they used to be so the others someone pointed out will be a challenge.

Oh, that makes more sense. The heat from the malfunctioning cooker may have resoldered these points badly.
I was curious how like half the points were bad, and that explains it.

Unlikely any heat from the slow cooker did anything. Solder melts at 370F. A slow cooker is never going to get anywhere close to that hot.

Strange that all the bad points are in the lower half of the board, and that most points in that half are bad, then.

It’s most likely that it’s related to the original manufacturing. These will be machine wave-soldered, not hand soldered, and having quality vary across the board isn’t impossible if the setup/operators were less than ideal.

5th pin down on the far left side in the picture.
There's no solder on the pin.
Most of the joints are questionable, that one is flat out bad.
