I know this have been covered before but i am just documenting
It is a securitying 7x XM-L2
The Aluminum mcpcb no talk just PICS
Sorry i don’t have a pic for the mcpcb before starting
Now with the pics
Drilled
-
Used 2mm copper wire then HAMMERED :evil:
Filed and polished
I hope you like it…
interesting work there keep us posted how it goes
Nice work. Did you drill a hole and then file the slots?
Yes i drilled a hole in the middel then with a bench drilling machine i filed the slots by going right and left 8)
Then i HAMMERED IT :evil: ( i just want to use the Evile emot 
)
Nice!
Nice work! How will you be re-flowing the emitter?
Nice! How much time did it take?
Not much 4 hours maybe or less but it really worth it
When you hold that mcpcb up to the light, can you see any light coming through the edges of the copper?
Also with all the pounding is is very important that the mcpcb is still perfectly flat.
Just a couple of things to look out for. Seems to be coming along nicely though.
I dont think there is gaps and even if there is the solder will fill it
I was just lazy to file the holes edges to square and i filled the copper slugs to fit the shape of the curved edges 
Successfully reflowed and tested
Sorry for the bad phone pic
I think this is still a good idea for larger mcpcb’s, what current are you aiming for?
Just a BLF SRK FET driver :evil:
You know those LED’s are in series, right?
Looks pretty parallel to me. Inner circle is common anode outer is common catode. That’s parallel.
…my bad - I assumed it was series.
Looking at my old 5* board, I see it’s parallel also.
….carry on…
Nice work gamezawy, and with so much emphasis on HAMMERING too.
