LED PCB

[theatrus]

Have you thought about making your own pcb's using a 3D printer? If you don't have a 3D printer maybe you could partner up with someone who has one that would be willing. Ohhh, I don't know who but maybe the guy who's post is above this post might be interested. Baahhhhhh!

Wish it worked like that, but sadly no ;) Milling PCBs also won't work on metal core substrate as you can't control the depth enough to not cut through the insulation material and into the metal core (though works fine for copper clad fiberglass).

I might just tackle one of these for fun. Could be an interesting project for the weekends. I do wish they sold the diodes also....would save me shopping around in different locations.

That really would be ideal though.

I use China for prototyping (... you can't beat the cost), but move to a US manufacturer for the metal PCBs once I have something nailed down. The thermal performance of the US brand-name metal core materials is a lot better than the Chinese budget stuff (though you could get it made there as well).

I know you have connections and the materials and all of that,but how much would the array cost you built in the start of your new thread ?

I would love to know why they put cyan on the violet channels,I'm sure that would make for a weeeird color.

Realistically, qty 10-50 metal core PCB from China (single layer) will run you about $50-80 shipped, depending on the number of square inches of the bounding box. No one will sell you one :)

I feel like this one is better the other one from Kiwi:

This one is actually from Kiwi on the 21 led array already loaded out:

But what if YOU were able to make them for buyers,is what I guess I really should have said lol

Fully custom design or just a different load out of an existing board?

BlueAcro boards use Luxeon LEDs which cost more

Sorry but that dude's voice is amazingly annoying!

I agree but he does really know his stuff with electonics!

I was referring to the kiwi board mentioned on the 2nd page though.

Still learning... thanks!

Both lol ?

I've tried to check it out but my phone is warning me against going there.

Really varies. Loading new LEDs on an existing board is not an issue - the PnP is already all setup so it’s a matter of switching some feeder slots around.

I like making new boards for sport if they’re not totally crazy. I usually don’t charge if I think it’s viable as a more general appeal product or if I want to try a concept out. I can’t load and assemble or even procure the parts at anywhere near the cost of direct-from-Shenzhen though.

If you’re interested in the pricing dichotomy consider an inductor I use on my LED drivers. The Abracon part is a $0.40 in quantity, the equivalent size and shape and similar spec Chinese Sunlord part is... $0.06 in quantity. This pricing structure of course doesn’t hold for name brand Cree/Lumileds parts, unless they’re bottom bin or fakes.

This really ideally what I am looking for,there was just schematics for it not price:

Looks like a single Luxeon Z, on FR4 with thermal vias. Are there LXZ stars available?

That I don't know,something like would be sooo ideal to mess with. But something with about 10-14 spots for diodes.

If you want some blanks of AcroStars let me know :)

Shoot I may have to take you up on that,maybe 1 at the most just to mess with.
