[Feeler Thread] Copper direct-connected 20mm triples and quad universal MCPCB boards


I may estimate readiness as 80-90%

We’ve check this factory samples (no gaps nor not-register like Noctigone)
We prepare and transfer Gerber files to factory and check all layers again
Today I’ll pay for mold production

Stay tuned )

If I may ask, what's this statement based on? If you've seen issues with them yourself, what was the sample size? Or is this based on a picture somebody uploaded that then got passed around until 'everybody knows' they must all have issues?

Well, I’d prefer do my work right way, not discuss somebody’s mistakes

Just put it here

You have a funny way of not discussing it.

comfychair, bingo!

I'm sorry, but what I mean is you're playing the awfully tired passive-aggressive game by bringing it up first, then saying you're not going to talk about it, and then posting a picture of who-knows-what from who-knows-where. You just showed up here doing... whatever you're doing, and Hank has been good to an awful lot of us for a long time.

I have had a lot of Noctigons in my hands and not seen anything like what's in your clever picture.

You seem like a nice fellow though, so I will just wish you well in your future endeavors and let this play out as it may.

Ok, let’s return to serious side, sorry for my clownery

comfychair, first copper direct connect I’ve try was SinkPad and second Noctigon

I have some censorious remarks for both

I don’t base on somebodies pictures or judgment – it’s my own experience

All sinkpad have problems with design: very thin power paths plus no way out for solder from thermal-pad

Some noctigons (I’ve bought it from IO) have problems with gap between thermal-pad and power-pads layers and some others have a problem with positioning

Pictures above-n-below (it’s my picture and these boards was bought from IO) shown it

I’m understand baffling complexity of producing copper MCPCB

And now I’ll try to produce some better product, no more

Thanks for making these boards and posting here, your boards really look nice, and thanks for explaining how they will be better than Sinkpads or Noctigons. I (and others) have not found a significant lack of performance with either Sinkpads or Noctigons (it may just be ignorance ;-) ), but I guess that if you measure well you could see a benefit from the thermal pad and connecting pads being exactly level.

I'm not a large-scale consumer, but I'm in for three triple boards and two quad boards, if only for the very elegant design :-)

Well, triples almost ready

They look great.

Feels a bit like klingon styling. :bigsmile:
The copper klingon triple. :beer:

Nice, I'm still in for a few :-)

I'm not entirely sure how I'd use it yet, but I'm in for a few too.

Interesting.
Able to supply with chosen led already mounted and tested to work ?

I actually have a few of the Carclo quads so this is interesting. They are even more floody than triples however. Khatod makes a 20mm quad that has deeper optics but the peg footprint doesn’t match the Carclo quad(pegs closer to edge on Khatod). To work with both optics the peg holes would need to be elongated radially.
-Edit
My bad, those are 25.4mm optics but I believe the led footprint is the same as on the 20mm Carclo, the extra 5.4 mm allows for the deeper optics. Still, a board that works for both would be nice. Probably too late though.

I’m in for a couple of parallel triples and a couple of quads

Any updates, particularly on the quad version?

Guys, sorry for delay

First batch was moved to trash (It’s happened sometime, yep)

Second batch of triples is ready and I’m sending it to participators right now

After that I’ll count the rest and offer it here

Quads must be ready this week

Hope update the thread soon

wow, that is a lot of boards . What was wrong with the first batch I wonder?

(still in for a few triple and quad boards :-) )

One US guy ordered 750 pieces )

As usual – some gap between thermal-pad and board layer. They offer big discount for it, but I was unbending and force them to re-make it

Triples? Quads? Why would I want them? What would I do with them? Ive not even reflowed a single led let alone 3 or 4.

But Ill take a one of each if these are pure copper.
