Ok thanks a lot!!
I will Try it this week

I Made it worse. Either the solder Paste was too dry or i removed it too early from the oven. The solder Paste was very Hard to Push out of the syringe. This is How it looked ( i put a Bit More there after the Photo ) . Then I put the whole thing in the oven and After around 8-10 mins at max( 220 degree celcius) i removed it from the oven to cool down After that it was very easy to Break apart.Is there anything i can do now , like trying it again at longer cooking duration?

You can use a little more solder paste and try again.

8 to 10 minutes is not enough since the copper heatsink is quite massive. I estimate maybe 20 minutes. To make sure, add some more paste near the edge of the copper plate so you can see when it melts and starts to look shiny...

do i have to remove the Old Paste or just put new one above?

 

[FlexxRocket]

[FlexxRocket]

I Just put it in the oven

First i put heat resistand tape around it :
Then it was in the oven for around 22min:
This was the result : ( Its a Bit dirty from the tape but i will clean it Today with cleaning alcohol)
But there is a silver seam all around the copper plate and Its solid)

i put heat resistand tape around it

seems this was not the best idea

but from the picture it looks like the soldering was successful!

i realized that also After Soldering
But maybe Its somehow cleanable
Edit: Its Not
