Say what? Got a link?

here you go. But with 319A, there’s no need for a special board, normal dtp sinkpad or noctigon with for xp footprint.

They do work and I tested that they work well (though not as good as the VirEnce board), but it requires scraping off some solder mask to widen the solder pads.

djozz,

They seem like the work just fine.

But for the slow among us (me included) can you add a list of the LEDs that fit this board to your original post?

and maybe compare to the (what is it?) xp? series noctagon copper bards that we would otherwise need to use.

A DTP board will always heatsink better than the board from the OP, but only work with leds that have a (neutral) central solder pad.

The OP board fits all leds that have just two solder pads for cathod and anode without central solder pad. And there is not so many leds that fit it that are interesting in flashlights, it is an obscure board!: almost all midpower leds have the two pads but are too dim for flashlights, a series of Nichia UV leds fits this board, Luxeon Z fits it, and with some scraping the Nichia 144A series fits it.

Maybe it’s not (only) the dielectric layer that is better than usual, but it may well be (judging by the picture) that the copper layer on top is thicker than usual.

I was thinking XQ-E, but they’re probably too small for that.

…and the gap between the solder pads is smaller so there is more copper directly under the center of the led. (I did not ask specifically for an extra thick copper layer, and have to look up what thickness I actually got)

djozz, it may not be that you got an extra thick copper layer, but that they made that other one cheap, with an extra thin copper layer. Wink

I mean, the djozz board versus the generic board. I know the copper core weighs more than the aluminum one. I’m wondering how much difference there is. Just curious.

I’m sorry Lexel, lots of things going on on BLF today, and then there is a life too (work, shopping, making dinner, reading book to my son, comforting him later at night when he wakes up with bad dream).
I will go through my PM’s now.

Djozz is very busy lately in part due to the 219C group buy, I am sure he will get to you as soon as possible.

I used these MCPCB’s to test a nichia 229AT today. The results were surprisingly good. It beat out the 219C all the way up to 4.5A when the lack of a thermal pad and DTP caught up with it.

They have the lowest Vf I have seen to date as well!

I had my Nichia 365nm LED in the Convoy run to long on the stock MCPCB it has lost brightness on parts of the emitter, 700mA are not good

Too bad I did not had this board from the beginning

Could I get 2 of these shipped to the UK?

About to order my first S2+ UV, and a reflow onto one of these seems advisable!
