The collected works of MisterDNA - Page 2

I didn't know they were hosting another test or I'd have made the drive out to watch. The spectator area is about a mile away from the UUT, but you can still feel the blast at your core. Video does not do it justice, but if you can't be on-site, it's a good substitute.

In BTtF3, Doc and Marty burn out the DeLorean by trying to run it on whiskey. Doc was smart and any redneck can make moonshine. Why not further distill the whiskey into pure (more or less) ethanol and burn that? It would have worked, though the seals on the fuel lines would need replacing in a few years.

And, if it simply did not work, they probably would have attempted one of the aforementioned ideas. The problem: they blew out the fuel injection manifold, and Doc guesstimated that it would take a month to fix. Taking that major of a component from the in-the-mine DeLorean really could have screwed up the time line, though I expect that taking the gas might not have. So, at that point, there was not much they could do.

A possibly better idea: leave town.

And that wasn't even the fuel injection manifold that shot out. That was the distributor, I think. Keep in mind I've never seen the movie on anything other than a 13" CRT with a VHS tape as the source so it was kinda blurry.

Oh what the heck.

I'm having a hard time wrapping my head around this one. They were amazing in their day and age, but there are still people out there developing dead-serious stuff for them. What am I missing here? Should I get one and find out for myself?

Speaking from years of experience as a tech:

Through-hole mounted parts (including DVI connectors, for example) generally won't take a baking. They're meant for wave soldering at most and that's it.
Surface-mount parts will take a bake because that's how they're soldered in the first place.

Reflow temp for tin/lead solder is about 200C.
RoHS lead-free is about 260C.

The board should be as close to bare as possible when baking. That includes the heatsink/fan assembly. If it wouldn't be on the board while the solder paste is still in paste form, take it off during the bake. That includes large heatsink/fan assemblies on GPUs.


Heat guns work wonders when installed parts prohibit baking the board. Make sure you heat both sides of the board evenly, though, since they warp and BGAs hate that.

The hell? I come back and see this? Looks like stuff has changed in the past two years.

Then a lot has changed. We were cohesive back in the day (circa 2006).
