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

Hi!

I’m Alexey ‘Dsche’ from Russian ‘Fonarevka’ forum and I’d like to present you one of my project: universal multi-XP* (+ Nichia 219, Samsung 3535 etc) copper direct-connected 20mm boards

Here’s triple:

Here’s quad

and its ability of connection

Price MUST be less than $2 for one board

Very nice.

Are there optics available for 4 Xpgs?
The 3 led version is already available so that’s not so interesting…

Carclo has a series of quad optics, I guess those are the ones the board is designed for.

Sure, budget ones here (10Off code till December)

I'd really like to see these copper quad boards available as there's nothing comparable on the market at the moment.

Also the stylised surface pattern is a nice touch.

All we need now is a driver that could push a 4x copper mounted XP-G2 setup to it's full potential, to 2A-3A each if not more.

I picked up some of your triple boards (with the larger copper surface area over the dielectric layer) before direct copper ones were available and were happy with those. I’d definitely be interested in the direct copper bond quad board.

Any idea on the time scale and when this projection would come to fruition?


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 ?
