GB: 20mm Sinkpad copper boards CLOSED

I’m in for 6 xml at $2.5. If cheaper I’ll order more.

Put me down for 10 XM-L Bubble Mailer.

Does anyone know if different reflow solders have better or worse heat transfer characteristics?

no idea, but I’ve had several people recommend using solder paste as it makes it easier to get reproducible results (same thickness, no excess, etc). No idea personally, but might be worth checking out.

I think it’s also what the peeps at Cutter used in this video:

5 xm-l

5 xp-g

I’m hesitant to say this but you guys are strongly opposed to introducing this GB to the other forum just for the sake of getting more people, right? :smiley:

I think it would be they would strongly oppose to joining a blf group buy. If you linked this thread over there… I bet it would be gone within 5 mins.
Might be worth a try though

I’m up for 10 of each (XML and XPG) if we get over 300, 20 of each if this goes over 1000.

My original intention (I was going to do a group buy) :stuck_out_tongue: was to add CPF to the list of people in the group buy if we needed the number made up: I see no problem with it… they will just do the same over there regardless (or someone will pop up selling them for more). Nitro you have PM. :wink:

I’d be in for 10x XM-l’s! plain envelope should be fine

Been wanting some copper to play with :party:

Pictures:

XM-L / XM-L2: 20mm diameter, 1.6mm thick, LED-solder-copper, no dielectric bottleneck.

XP-G / XP-G2 / XP-E / XPE-2 / XP-C / XT-E: 20mm diameter, 1.6mm thick, LED-solder-copper, no dielectric bottleneck.

(Nitro just copy and paste the above code into the top post for pictures (if that’s possible) and I will delete this post).

I am In for 10 XML + 10 XPG. We need to push this over 300.

I wonder if any LED and parts suppliers would be interested in the group buy (might not work from a business perspective though unless they act as the distributors).

+1

6 xml 4 xpg please

I’m in for 5x XM-L and 5x XP-G/E.

hmm, looks like we could make 300

I’d be in for more if we get to enough to do 16mm (assuming others would also prefer those)

edit: I just double my request - and my quick tally just came up w/ 207 total (1/12/2013, 0903 est)

So u want 20 then ?

I asked for 16mm boards but we have to have $1500 down with a board design and we would then get 300-600 boards from what he told me

PS: 2nd post is updated please look at it if I got anything wrong please pm me

yes 15xml,5xpg. we’ll make 300 if you don’t close the buy too early :slight_smile:

somehow I did the very simple arithmetic of 1500/300 and 1500/600 wrong in my head, and I have now realized that even if we hit 600, they’d be $2.5 each. seems very unlikely, so forget I mentioned it….

4x XML

1x XPG

Bubble

2 x XML for me please!

I will provide a US mailing address later.

(For my HD2010 now that I know a 19.33mm star will fit (20mm can be filed to fit) from this review UPDATE: 5/19!! Review: ULTRAFIRE HD2010 from Tmart (warning: lots of pics!!))
