INTL-OUTDOOR Direct-Thermal Copper MCPCB Review

Flashlight Modding and DIY Parts

Thanks for doing the test and review PilotPTK. Very valuable information.
Seems like the process of making copper MCPCB’s is improving.
I’am sure it wouldn’t be long before will see them at all our favorite go to stores.
Thanks again!

Thanks for the review PPtk! One question. Can you look closely to see how the slug is attached to the base material? Is it one piece, soldered, pressed in somehow?

This thread has reminded me to hold off on my intl outdoor purchase till these become available

5

I always wondered why SinkPad pressed it from the bottom. Looks like they would have pressed it from the top like president Lincoln on a penny.

6

It really appears to be a single piece. I’m not entirely certain how they do it, but it’s a great design.

Cool! I’ll be snagging a few to try out.

8

Milling? Kung Fu magic? Optical illusion? Demon worship? I’d put my money on option 1 or 4.

9

how does the gold bottom affect thermal transfer?
Also have you tried removing it to see if it has the depression like the sinkpad?

10

Gold has 3/4 the thermal conductivity of copper… on these things it is not thick enough to matter.

11

Thanks for such a great review. Lets hope the actual production samples (solid slug design) dont change.

12

Thanks PilotPTK, these will really sell like hot pancakes and I hope Hank orders enough for everyone, the first batch sold really quick. Great to hear it’s of a good design and function.

Thanks for review…

As far as I can see from where Im sitting. The 16mm Sinkpads are the only copper MCPCBs that can be made into 10mm. The ones from intl-outdoor could be turned into 14 it looks.
But the ones from intl-outdoor will offer quite more bang for the buck. Flat underside and that there are space for access soldier to go away from the center is just icing on the cake!
Looks to be a winner! Cant wait to get mine…

Thanks PilotPTK for the review. Also a big rap to IOS in allowing PilotPTK to review this MCPCB before release.

15

Interesting, thanks for the review.

Will you do direct lumen comparison tests against the SinkPad?

Cheers!

16

Good to know that the MPCB bond to the copper substrate is solid, the MPCB on the copper stars i got from ledtech.de were VERY delicate.

Thx PilotPTK.

Thanks for the thorough review. And for the great piece of video art, loved that B-) .

18

Wow! This sounds very good! Looking forward to these being available! Just hope Hank doesn't underestimate the demand for these! Thanks PilotPTK!

Thanks for the in-depth review, PPTk! These look to be a great value. Hopefully Hank has a lot of these in stock…

PilotPtk great review. On your thermal test did you compare with the thicker Sinkpad design or were both models set at 1.5mm?

21

I kept them both at 1.5mm because I wanted to compare apples-apples. I used 20 degrees C as the ambient temperature and put the stars on an ‘infinite’ copper heat-sink. That means that it conducts the heat away at the rate of copper, but it never heats up. I set the thermal generation rate to 8W on the top of the thermal slug.

As you can see, the temperature rise is a little over 7 Degrees C in the SinkPAD Style board and a little over 5 Degrees C in the INTL-OUTDOOR Style Board. Not a massive difference, but not completely insignificant either. It would be more and more pronounced as the number of heat watts went up.
