So . . . . I baked a logic board last night

[sajunky]

let me clarify a little further.

the machine in question did boot, but when it got too warm, usually when playing videos it got the garbled display with lines all over.

In this case it seem to be ordinary overheating issue, so for others who read it, correct action is to replace thermal compound first.

As for baking for reheating BGA soldering, apply only when neccessary, but there is other method involved heat gun. It seems to be better, as it is localised and fast - prolonged heat is dangerous for the silicon structures. Professional reheating machines use neutral gas to prevent oxidation. If you read some specs sheets, you will see that reheating BGA chips is not approved by most of manufacturers.

How long baked life is extended? It could be few weeks, but also couple years. I read that reheating services are offered in some countries for money, but people report that it works only for few months. Other matter when it is for free.

Anyway, if you have more retired machines, let me know.

How did it taste?

i considered the use of a heat gun and believe it would be more effective.

however, i suspect it is a little more risky to apply intense heat to a small localized area.
one would have a situation where the logic board is sitting at ambient temperature of say 25 degrees, and then intense heat is applied to a small area of the board. i feel the heat and resultant localised expansion and contraction on the board has the potential to have an adverse effect on adjacent components - more so than the even and uniform application of heat to the entire board.

just like chicken actually

 

[Seriously]

Apple quality

Totally, those 1st gen MacBook Pros were solid, and ahead of their time. Just like all the others, I guess.

Why did it fail in the first place then.

Problem with heat gun and hot air stations is that if you are not careful the air stream may blow away very small and light light smd components when the solder is melted and then you wont know where they were originally.

Same problem is if you bump the MD or electronic board in the oven which cold dislodge the component.

hence my overly cautious approach in allowing the board to slowly cool before touching it

Well done lad. i have a few (close to ten) items waiting in the baking queue but could not gather the required commitment yet. Time to give it a bash I guess.

No problem then. But your next chicken will taste arsenium.

we actually used my oven as it is one of those over engineered german jobs.
one can do fish and vanilla cake at the same time without the prospect of "cross contamination" of smells etc, so hopefully from now on chocolate cupcakes wont have a tangy lead flavor.
also, and most importantly, it has an oven probe which was placed on the gpu to constantly monitor temperature.

biometrics' comment was tongue-in-cheek/sarcasm, and mine a fanboyish pro Mac, suitably in response.

There will be some failures here and there... The nature of electronics.

But on the topic of quality... Of course Mac has higher quality. From build quality, to PCB/solder quality, to the choice of chips for network/audio, to screen, etc. They fail less, too. Open one up and gaze at that sexy black mobo and solder.

You believe all the garbage the Apple salesman sell you? i gaze at a lot of electronics on a too regular basis so no more hard ons for me unless its a plasma screen in FHD with a naked beautiful blonde.

Right... Now I remember why I never give you the pleasure.

Pleasure was mine. AGE IS A BASTARD SO I BATTLE TO REMEMBER TOO.

anyway.... LIGHTEN UP MAN IT WAS MEANT AS A JOKE.

well, it's been a week now and i have tried to get the thing to crash.
it's a dual boot machine and a friend has been playing some games which are apparently graphic intensive (i'm no gamer - so i'm clueless in that dept)
still running flawlessly.

so now i'm on a bit of a mission to get it to crash (i guess this has become a bit of an academic exercise on an unused machine).

time will tell

Made by foxconn, chips can be found on normal pcs as well. As for failures there have been a few models with real serious issues rendering them useless, not always acknowledge by apple.

A different department in Foxconn. One that makes higher quality stuff.

Sure they can be, Macs are PCs too. The point is that one knows they're always getting quality. They're paying for it, after all.

Better stuff tends to cost more, simple.

And the bottom line is that the hardware is all perfectly compatible with OS X.
