LPC-815 LOC Harvesting Problems

[Toaster]

Lol everyone and their Dremels. I don't have one I used the file. Worked good

 

[Solder Blob]

I should get a smaller file too. But I just finished ripping out another LOC and everyone I do gets worse than the one before. I really believe these companies have taken the extra step to keep us away, by making these tiny heatsinx out of "TITANIUM"! I mean, after you break these little suckers apart, try to bend that stuff with pliers. I wonder what that small amount of titanium would cost if they did. Ahhh, I guess they wouldn't, but it's unlike anything I know.

I cut 1" solid round metal with two different kinds of blades and hack saw thru steel with a sawzaw, and drill thru brass and copper quite often, but this stuff is tuff as steel, but it's not steel because it doesn't stick to the magnet. On the other hand, titanium isn't magnetic like iron & steel. YOU do the math!

I don't think I'll be doing any more of these. Without the dremel, and going all the way in till I see the diode, I don't think I could get them out. Dremel, dremel, dremel! It takes me about an hour to get one of these things out. There's nothing to grab onto with a pliers.

An Hour!:huh: Takes Me 5 minutes, and I just use the Dremel with My helping hands. After I have cut both sides I grip one side with vise grips and with miniature dikes I pull the sink apart. It really is a piece of cake once You get your system down.

Yeah, I did one of these and it didn't give me any real problems. I think it was maybe slightly tougher than the BW512s, and the open can business makes it a more delicate operation, but it wasn't really an ordeal.

As has been said by many others, a Dremel is a godsend for this kind of thing.

I even used my dremel to slice an Aixiz module in half to get a diode out. This was Pre-Pyro's Awesome diode tools.

I haven't been accurate on a post since I've been a member! I thought we were talking about LCC's!!! Usually I just respond to year old threads! I don't even take drugs! One thing for sure, I need a better bit for my dremel. Even so, the LCC's I've done before were a piece of cake. But not the last two. I have a LOC coming soon. It'll be my first. Bought it on eBay.

Blob use the thin cutting wheel and not any other bit!!!

 

[Juniortore1]

Hmmm, well, I don't have a dremel, but I do have a die grinder, would that work instead? I just need to be more careful since it will go faster and the "blade" is wider.

 

[Solder Blob]

I have a grinder too, for big stuff. But this thing will grab your diode if you aren't holding on to it super tight and rip it out of your hands and smash it on the floor or just fling it so far away you can never find it again! Other than that, yeah, I think it might work! I know, it sounds sarcastic, and (it really was meant to :na but I still use that monstrosity to do tiny work at times. It's quick, but dangerous. I'm looking into getting a smaller one.......real small.

@ Coherent Light, is that the name of the bit? --"thin cutting wheel"...they have so many different bits. That's the name I will ask for "thin cutting wheel". thanx

I also used a Dremel. I was trying to be REALLY careful since it was my first LOC extraction. I put a tiny piece of scotch tape over the little hole (worked perfectly), then drilled one notch on each side almost down to the diode. Then used vicegrips and needle-nose on opposite corners until the diode was loose.

Riding on the high of my successful extraction and feeling quite pleased with myself I then I proceeded to drop a huge blob of solder on the positive pin, soldering it to the case quite nicely. I ended up ripping out the positive lead while trying to remove the evil solder. That killed the mood REAL quick. :banghead: Anyone have an extra they wanna donate?

BTW Solder Blob, the one I used was cutting wheel no. 409. They're very thin and they work great!

EDIT: Sorry for the double post...

 

[Solder Blob]

You still had options after the solder blob(no pun intended). I've soldered two pins together more than once. I probably unsolder one out of every 5 or 6 builds, especially if I rip an old build apart and want to start fresh. I'll unsolder if the wires look too close for comfort.

Option 1: Simply unsolder it, wiping any solder you accumulate on the solder iron off each time you get a little on. Solder sucker wire never works for me, so I quit using it.

Option 2: Make it a case (+) positive build. I'm not fond of this, but all my china stuff is always case (+). Better than popping a diode. imo

 

[Coherent Light]

Blob I can't find the number on my container of dremel discs. I can tell you the ones I use are not the thin wafers, but more like cut-off blades. Same as on a chop saw looks like some sort of fiber board. Hope this helps if not PM me and I'll send you a couple.

 

[Solder Blob]

@ CL ....thanx, I'll find one. I have the info I need now. I was using a small gray stone type wheel, which worked on many projects, and still is great for removing circuitry on LED boards, especially those little round processing blobs, but is now getting too wide for heatsinks. I'll get the one you mentioned. I have a large 10" brown metal cutting fiber blade, so I know what you mean.

Here's the gray wheel pic:

 

[Coherent Light]

Damn Blob with that thing You could just grind the whole HS away.

 

[Solder Blob]

Almost did!!!!!!!! .........OK, enough of this, I'm headin' to Lowes....And OMG, it's party time :beer: I may not be back 4 awhile. ......Later
