Does this look like it is really DTP?

No, this one is not DTP :sunglasses:

Thanks. That would explain why they are so cheap.

Thanks for this thread. I ordered the product linked above and hope it’ll work out (will report back once it is here and I found time to build a light with it. Coupon used: “THANKS15”). If there is any doubt or an issue with it I can still use the star for low-amp light applications.

Even in the worst case even a non-DTP mcpcb should be fine with 1-2 amps of current draw.

I think if you message Simon he’ll sell you 5pcs for 4.5$
This is the link of the DTP Boards that simon used to sell
Place an order on any item in his store without paying, then message him and ask him to sell you 5 or 10pcs

if you tell him that you’re from BLF forum and he’ll give you a 15% discount

YEs it does, because the centre pad has rounded corners.
The picture is too small to be certain though, but i think i have one of those here and it’s DTP.

[edit]
I see the pic is from Banggood.
The SKU is in the link, i’ll check it out.

Yep, these are DTP.

I bought one recently. (XHP70 version)
You can see the rounded corners of the centre pad, and there’s a kind of groove around the pad.

Hmm…I’ve been told somewhere that S2+ uses non-DTP PCBs. Does Simon use different 16 mm XM-L MCPCBs for different lights?

As I know clear C8 with biscotti was first old convoy model with dtp pcb in stock.

Yep, these are DTP.

Thanks, for less than $1 each I decided to give it a go.

[Jerommel]

My black C8 with XP-L HI has a DTP board too.
Bought it from Gearbest before the clear one hit the market.

The time that DTP boards were rare are in the past.

Less than $1? I only see them for $1.39 with BlackFriday9% dropping the price down to $1.26.

“thermoelectric separated” search @ FastTech

There are many available copper boards at FastTech. Let me list you the boards which I think of or can confirm as non-DTP:

https://www.fasttech.com/products/3596003

https://www.fasttech.com/products/3596001 Got one of these once, seems to be from the same manufacturer as the ∅14mm one. Converted it to DTP with a milling bit.

https://www.fasttech.com/products/3596000 Same smell as the previous ones.

---

The next board is DTP (thermoelectric separation technology):

Jerommel seems to have asked this here. Self quoting myself:

@Barkuti

The manufacturing process for these seems to involve removal of the circuit layer from the copper cookie with a depth equal to the sum of the thicknesses of thermoelectric layer plus conductive copper tracks (this is the reason for the central thermal pad to look like an elevated plain), application and separation of the termoelectric layer from the thermal pad, layering of the copper tracks and at last layering of the masking and contacts tinning. If done properly, thermal and electrically conductive pads are perfectly leveled.

Cheers ^:)

wow, Great info, Thanks alot Barkuti

so we can say that the one I mentioned is concidered a DTP Board but with 85-90% efficiency if compared to a Noctigon, right?!

Here’s the <$1 deal:

A few things from my wish list plus a random quad with a heap of good reviews that is on flash sale and a SK68 clone that seems like an OK gift for kids at that price.

Edited my post above fellows, I messed it up. :facepalm:

This board is thermoelectric separated (aka DTP).

Cheers ^:)

g_sintornillos, that 16mm FastTech board is the same, a thermoelectric separated one. Nice single piece price.

Cheers ^:)

Thanks, Barkuti. The other link doesn’t work (seems to be a cloaked affiliate link). Those links should go in the “User Negotiated Deals” subforum.

edit: Thank you! the link works now!

[FPV]

Just to confirm:
My 20mm copper MCPCB order from Fasttech came in and the board is good! It really is DTP (as stated above by Barkuti and others), I am currently building a C8 with a XP-G3 on this board.

Thanks everyone for your input, this MCPCB looks great for this price. It appears it was stamped from a copper board and not milled (like other, more expensive MCPCBs) but I honestly don’t care about that.
This board is good for modding projects.

The one I ordered is here:
https://www.fasttech.com/p/6222001

edit: Just to update my post after looking at the product pictures, the DTP copper strip under the thermal pad is slightly smaller, more compact than the picture. It shouldn’t make a difference though.

edit: spelling errors on a few things, sorry.
