We currently make DTP copper mcpcb many,any size have,We customize and design MCPCB according to customer requirements.
Sometimes,we made some standard DTP copper mcpcb,such as 10mm,16mm ,20mm,31.6mm with cree xml and xhp50 xhp 70.
It would be great for you/and us if you consider producing a NONDTP copper XBD 16mm copper pcb- there isnt such pcb awailable at the market and those IR Oslons badly need one

Well, at least with regards to those leds with a lack of thermal pad, no one wanting to ask for an orders of magnitude improved thermal conduction dielectric?

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.
Today I received an order of ledboards that I had made by Shenzhen Kerui Electric Industry. It is 128 pieces of Nichia 119 16mm diameter non-DTP boards, but I tried to maximise the heat path of the boards. For several leds without central thermal pad I would have liked this type of board but I could not find it: Nichia 119, Nichia 276A UV, LuxeonZ will fit too, and the new large Nichia’s (if available at some point) will work too by scraping off some solder mask. The costs for the 128 boards (I ordered 100 and they made 128) were, including shipping and taxes from dutch customs, 258 dollar, so about 2 dollar per board. I’m going to test these boards against a ‘standard’ alumnium Nichia 119 board (came with my Convoy S2+ 276A UV light) to see if they really do a bit better (but I do not expect DTP performance).
I’m going to sell these here on BLF for 2 dollar each plus shipping, so cost price. I have no idea how many people are interested, and it may depend on how well they test
Details:
-16mm diameter, 1mm thickness to support many common flashlights
-core = copper
-the two electric led-pads widen in a as large as possible pour to help the heat to go sideways and then pass the dielectric layer over a larger surface area.
In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not. http://asflashlights.com/ Everyday Carry Flashlights, plus Upgrades for Maglite.
With the Nichia119 board order I received a couple of their XM-L/XHP50 DTP boards for free, which is a nice gesture. I believe these are the same that vestureofblood sells at the moment. They look good and I checked how flat the pads are with a razor (good!) and also sawed one in half to check the DTP pad (good too!). I see no reason yet why these boards would not perform very well. Here’s some pictures:
Sweet. SO the pad is actually raised up in the center above the dielectric layer. It looks like only the thickness of the solder mask layer is counter sunk.

Now, where are those beryllium oxide and/or synthetic diamond dielectric MCPCBs?

Thanks for doing those, djozz. I’ll be in for a few.
Thank you for your post,But I did something wrong about the express and got you into complicated custom duty trouble later.
This time I got a lot of lessons.
It mainly use for automobile headlight,as this product
But This design is two side derect thermal path copper mcpcb,there is two sides have circuit.
This design is in order to better solve the heat dissipation problem.
Nowadays,direct thermal path mcpcb not only use flashlight,but also other area.
For example automobile headlight also have thermal request.

This is flashlight forum. There are lot of diy flashlight modders here.
So I bet any kind of flashlight dtp MCPCB’s (small, medium large, triple) will be appreciated here, and of course please put more nicer pictures of them.

The great thing about this company is not so much the availability of the usual DTP copper boards (they sell them alright), but the possibility to have any board of own design made in reasonable small quantities (from just 100 pieces on) and a fair price, with for a chinese company very good communication! Their posts show boards that may not be useful in flashlights, but they do show what variety they can make.
djozz would know about the design requirements, since he has some boards that he designed and ordered from them already. But, until he answers, I’ll say what I think would be nice is a simple ability to upload designs made in Eagle or Diptrace just like we do for driver boards from OSH Park.

Yes,I know your request about show the flashlight picture.Yes,we hace many flashlight DTP mcpcb.For exsample quad DTP mcpcb.
For exsample,we work with fenix,they have many shape board request.
This is a sample circuit board,But have company name.
We mainly order according customer orders,May be have some in stock.
Sometimes,we also have quad DTP mcpcb(2layers mcpcb,circuit more compex),2sides DTP mcpcb for flashlight.But for many reason,I
cannot show it in public.
So I just show some usual DTP copper boards,we make some for stock.
The google translater is killing.

This is our company direct thermal path copper mcpcb testing report.
Can you list what size MCPB you currently make?
Can you list what LEDs the MCPBs currently work with?
Thanks!

They would sell even more to us if they would be dedicated to flashlight dtp boards.
But 100moq as you said is not much for our own design.
About design. Can I just hand scratch something?
Plenty of us ain’t engineers so readily available flashlight dtp boards would boost their sale imho.
They could offer their XP or XM boards design from wide variety of diameters for less hassle for us non designers.
i agree.
if we can come up with a design board for them to make triple or quad LED then it would be great.
It’s sux that I cant make design board
Nico -.-
djozz would know about the design requirements, since he has some boards that he designed and ordered from them already. But, until he answers, I’ll say what I think would be nice is a simple ability to upload designs made in Eagle or Diptrace just like we do for driver boards from OSH Park.
