Right. And the reason why it keeps breaking? Well, the solder on the board might not have any flux left, so it might have trouble flowing properly. There could be a cold joint, etc.
If it fails again, one possible next step would be to grab a multimeter and test the resistance across each component on the board. If the resistance is infinite, that might be your problem component.
- niels_olson 12y agoDon't you have to isolate components from the circuit to check resistance? Otherwise, you're looking also the other components look like the other arm(s) of a parallel circuit.
- jamesaguilar 12y agoYou know what, you're right. I saw a video of someone testing that a chip had been soldered on correctly with a multimeter, but he was testing for the lack of a connection. Testing for a connection would not be done this way.My bad.
- fest 12y agoThere's more than resistors on logic board. Also, by even touching component leads with multimeter probes is sometimes enough to connect the joint back thus fooling you to think connection was ok. Also, the problem might as well be one of the numerous chips in BGA packages whose connection points you can't even see, let alone- probe.
