Cleaning a PCB

[Mauzy]

..and this _used_ to be a equipment rack till I got hold of it.  I'm still finding uses for the stuff.


To get back on topic,
 I _finally_ got a message from the seller, and he thinks it's just soda.  I'm going for traditional cleaning (using the advice) before going for dishwasher. it may work out

What the hell is that? Is that a real dedicated Starwars? It looks like it but that Atari controller looks HUGE.

I recently obtained a set of Joust boards that have suffered what appears to be a 20-year old cola spill -- while I am not afraid to put them in the dishwasher, I am too lazy to remove all of the socketed chips, so will probably spray and wipe the boards as described by Xiaou2.

You're going to have to reseat the chips most likely anyway... they always need to be pulled and cleaned on boards like that.

...and I doubt any of us has a $20,000 PCB.  

I have seen people on eBay who obviously think that they do 

I helped a friend do some retrofit work on one of their ENG helicopters (they build them, not own them) and they had to remove an old mini camera. the cord cost $520,
and since they were removing it permanently, there was a minor argument as to who got to cut that expensive cord in half...

Tearing obsolete expensive stuff up can be a lot more fun than installing it sometimes

The Atari-like controller is the right size, it's the scale of the rest of the cabinet. The cabinet is only 28" tall and the monitor is 9". A better question is where the ---fudgesicle--- he got a 9" Triniton.

That's not a 2600 controller, it's a "game in a stick" and has NTSC output.  2600 controllers don't have a silver Atari logo and they don't have buttons on the side.

Corrected, you happy? Any other inconsequential details you would like to nitpick on? Would you like to discuss the graphic on that cabinet? How about the shape?

Hey, Chad, you want to quit derailing kayoteq's thread?

Peale, can we get a cleanup, aisle 1?

 

[ChadTower]

I mentioned that because it means he is using a TV... wasn't clear if you meant Trinitron as in PC monitor or TV... and the evidence was there to clear it up.

HarumaN, seriously, you seem to have a mancrush on me.  Ease up, I'm married.

Just to be clear, I was at the controls when I derailed the thread. It is a Trinitron. And I appreciate the confusion with a real one. That was the goal.

(back, finally on topic:)


Okay, finally got the PCB. and some insight as to where it came from, basically a 'building chock full of games'. 
 More on that later (as amtrack announces a delay)


Ugh.. if that's soda, I'm quitting sodas. Here's what I've done so far, since the store was closed for the cleaner.
application of liberal amounts of alcohol applied with q-tip, 1/2 hour soak, then application of high-pressure air (4-60psi) over and over.
The most effective part of that, weirdly, was when moisture got in the air stream, it provided a dishwasher-like effect. ;'

I call it 'dry washing', since it pretty much knocked the
whatever-it-is bit by bit off without any apparent damage to the components..

Before: Scary muck with actual chunks of I-Am-Afraid-To-Think:



After:


Not bad for the initial cleanup. Using proper electronics cleaner should help with the rest. Main concern is bridges on the ICs.
