Another Cree CXB3590 DIY thread

Yes...I hope you get well soon...I can understand that, I become old!
And trust me I know that all the little trouble of life can affect the grow...
I am sure that plants can fell the growers mood...
Have a great day ★
 
Well I got some work done on the light today thanks to Limosnero. We were talking about his new light today and it got me motivated even tho I'm still not feeling real good. It's ready for Cob installation tomorrow and I made a plastic templet to apply the thermal paste. I can screw it to the heatsink then use a single edge razor to spread the paste evenly,hope it works good.

Thought I would put up instructions for my templet to apply paste for CXB3590's using the IDeal solderless holders.
I made a new one with a slightly smaller area for paste because quite a bit squeezed out with my first one.
Pictures pretty much show everything,1.97" between the holes and 1.125" square hole cut for paste.
I used the razor shown to make the templet and spread the paste and the compass point to mark the screw holes.
With a flattened heatsink the sour cream lid is plenty thick,if your HS is not perfectly flat you may need a slightly thicker templet.
Forgot to mention that I used the screws to align the templet then taped it to the HS and removed the screws then applied the paste.

Have you measured the thickness of the sour cream lid with a digital caliper. Sounds like it would be pretty thick and apply more paste then what's necessary.

My first templet was made from a potato salad lid and is slightly thicker so I think the sour cream lid should with the slightly smaller hole should work fine,I can try it out and see how it works and post my thoughts.

It will work no doubt, I am just curious as to the thickness of the material. You may be just applying more paste then what's necessary that's all. Thinner the better (to a certain point)
