Are you saying the actual led actually fell off or are you talking about the light guide? I have had a light guide fall off on one of my units before. If its the actual led how did you reattach it?
Yeah... the LED is SMT, so it probably didn't fall off, but the little plastic thing easily could have if the package was thrown across the room or tossed onto a truck carelessly (not infeasible). Watching a large package sorting operation a la USPS, UPS, FedEx, etc, is a hair-raising experience.

Yes, regarding above post, I worked for Securicor and DHL and saw how things are loaded onto trailers, sometimes thrown 2-3 meters forward for it to land hard on the floor, after that half a dozen other heavy boxed thrown on top of it. Only exception is the very top of the range service, for which a great premium is charged but the boxes are handles with more care.
I hope the Mini-Rig has some serious packaging.

I've dealt with surface mount before, made sure the polarity was correct and have a working led again.

I've talked with someone who worked at UPS a while back... same sort of deal.  They would laugh at packages that said "fragile" on them, and simply toss them even harder.

Really, that's why you need so much foam and bubble wrap to ship anything safely.  I'd say that the BFL units are wrapped pretty well though.

The Single has little weight, posting something like that it pretty easy, MiniRig will be the real challenge.
I hope they ship a test MiniRig around US before shipping it back to themselfs to see what weaknesses the packaging might have.

While you're there with your spy-cam glasses, mention to them that they don't need to scrape the top off the chips, or any other 'damage' they do to them to hide what they are, any more.
Maybe that old lady can get more boards completed more quickly that way Smiley

Can anyone tell me what's the best way to cool a BFL single with a fan?
I have one of these usb fans: http://www.amazon.com/Thermaltake-Mobile-External-Cooling-AF0007/dp/B002OJN250/ref=sr_1_2?ie=UTF8&qid=1337559123&sr=8-2
I currently have it sitting on top of the single and pulling air upwards. Is that the best way? Or maybe having it blow air in from the side? Or do I need to remove the case for a fan to be effective?

Personally, I despise thermal grease.  I plan to replace the grease in my mini rigs with phase change material (PCM).

Some info:
http://www.electronics-cooling.com/2002/05/understanding-phase-change-materials

Where I buy it:
http://www.opentip.com/Electronics/Startech-Heatsink-Thermal-Pads-Pack-p-1075383.html

Also on Newegg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16835230030

Experience has led me to love PCM for CPU and GPU cooling.  Never tried on an FPGA, but I'm definitely going to.

Just NO. Much easier to use but not better cooling.

To each his own... those are usually the types of pads people try to avoid though!  They don't conduct heat very well.

So I received four BFL today in one standard USPS box. (4 BFL, 4 Power Bricks, 4 USB Cables) It was severely dented on all corners. It looked like at lease at least one of them was going to be in a bad way considering the weight of the package. Luckily, I have all four up and running without issue. No dents, blemishes, or pieces rattling on any of them.

Thanks,but I have grown VERY fond of Ceramique for CPU's & GPU's,for the last 6-8 years,but for these FPGA's I think it's a little too thick.

I'm mainly curious about what folks have actually used for the FPGA's.

So far MX-4,any others??

Please keep the suggestions coming,Thanks Grin
