Conclusion? There may be significant delays. [speculation and personal opinion]

I don't think this comes as a surprise to many. If the ASICs aren't on the boards yet then I wouldn't expect that the other components would be on there already. They will probably reflow everything together (or have a contract manufacturer do it).

You would NEVER run production this way.... , the MAX you could get away with is when you have a double sided PCB, THEN you can pre-place the component on the other side in advance.

IF you consider placing the board MINUS the ASIC, reflow....
HOW THE FUCK are you going to apply solder paste INSIDE the other components and prevent the SMT machine from smashing the other high rise components when you place the ASIC, then you have to double re-flow....

As regards burn in...... Just look at the Bathtub curve and you will see WHY there is an optimum burn-in VRS temperature profile.
MOST if not all the failures occur very quickly on the downward slide of the Bath Tub.

BFL has already pushed back their shipping date more than once, surely people have a right to complain each time there's a new delay. If they'd shipped in October as originally announced those early pre-order customers would now be hashing away at 50BTC blocks without any ASIC competition. Now it appears those early customers won't beat the reward halving and may not even be the first end users with ASICs. The difference in ROI and profits for these early adopters cannot be understated.

Looked at from a competition standpoint, BFL has captured the bulk of the ASIC market by announcing a delivery date that was horribly unrealistic at best and a flat out lie at worst. Given the stakes involved and the serial misbehavior of the company in question, I'm surprised there aren't even more BFL bashing threads.

Why people feel the need to continue to repeat the same thing, over and over, I'll never understand. Great, they're going to be late, not like we haven't expected, nor known about that for a while. No reason to post up a new thread or post every 2 days shouting, "BFL is late!"

Well, only if you are speaking solely for yourself on this.

Every customer of BFL is expecting them to be on time for early December. These are actual expectations.

I don't know why you might think that all customers expect them to be shipping later than their current shipping target? Either way, it was a message made on 11-10-2012 and the message is referring to the process in the "future tense" rather than present or past tense. (Hasn't arrived yet?)

So that leaves about 25 days from that message for outsourced assembly and maybe 5 more days for final assembly "in house". (HSF/Case etc)

-----------------------------

A follow up question that pops into mind is:

It is now 11-15-2012, 5 days later, have the ASIC chips arrived yet?
(20 days now left for board assembly and maybe 5 days for secondary assembly. (assuming they overnight the whole pallet of assembled boards to and from the external assembly house.)

Another good question:

How long does both stages of assembly take in terms of time?

-------------------------------
As BFL is poised to be the first to ship out of all the vendors.. supposedly ..are they meeting their scheduled timeline?

Or will it be something they will "only know 3 days before" the scheduled date at a meeting they have?

There is more to Bitcoin than bitcoins.

I wish they had a live webcam in their assembly facility.
Something like http://www.nanofab.ualberta.ca/lab-information/view-our-facility-2/show-a-camera/?nf_CName=WCAM

It appears that it has to be shipped to the assembly house for preliminary integration. Let us (speculators) see if the target dates are met.

BFL has already said their ASICs aren't done at the foundry and they don't expect them until the end of November. This shouldn't be a surprise.

Exactly. The cooling cycles and subsequent thermal flexing will expose any solder defects. And as much as you'd like to run your device forever, the host can crash, the power can go out, etc, so it will be turned on and off more than just once

Quiet you. My hardware will run forever and ever.

Until ASICs come out....

I would like to see it turned on, hit steady state temps, turned off to a complete cool, and repeated several times. Shouldn't take too long, and would be much more important than a single, long burn in.

How does that test anything?

1) I don't plan on turning my Single on and off several times a day. I plan on starting that thing up, and letting it run for weeks on end, only stopping to update CGMiner.

2) Running for even an hour doesn't mean anything. I had a 5970 that would randomly be declared SICK, but would take anytime from 30 seconds to 12 hours.

Squeept's idea isn't a bad one. Turning it on/off will cause all the chips and soldering points to expand and contract as it heats up and cools down which would certainly cause any soldering/connection problems to surface.

If it runs at spec speeds for 12 hours with no problems, you guys really think that this would not be sufficient enough?

Even 12 hours seems extreme to me, but maybe I am alone in this.

No, you're not alone. It's almost like some people enjoy ignoring the math. The same people probably buy a 20 dollar insurance policy for their 40 dollar, almost never fail, devices. It's nuts.

Jeez folks, BFL sure does take some shet here, some for good reason, some not.

This is NOT a good reason to give them a hard time.

We're not "sheting" on BFL.

I am just stating that IMO a 24 hour burn in is not really necessary to determine faulty rigs.

It could be determined with a minimal/non existent margin of error in a shorter time frame.

There aren't any moving parts except for the fans. These things are meant to do one thing only (hence ASIC) and that is spit out hashes.

You are surprised by this?

Who said I was surprised by anything?

I am just pointing this out. People clearly think all the Pre-orders will ship at the same time. There hasn't been any indication to support that. This is a post to inform others of that reality.
