In reply to Cathar: thanks for stopping by!
I had to lookup "Pantograph mill" to see what you meant. Interesting. Perfect for prototyping!
Since I'm not going the EDM route, 0.9 and 0.6 are my target. I'm going to stick to your prescribed ratio, which strangely enough matches EXACTLY what you wrote above (1.5 to 0.8), where mine varies between 1.5 and 0.75 .
Since I don't expect my pump to put out a formidable flow rate, I think I'll stick to 5mm fin height. Does that look about right?
"The AMD die is actually 1.25mm off centre horizontally, but is centered vertically when looking at the socket with the latch arm to one side." Noted, thank you sir!
I also drew this thing up with my l337 MS Paint skills (ooh, aah!). I'm getting in touch with Uta for a CAD rep, since MS Paint really can't do it justice.
As for the white space over the core, I'll try to calculate what I've come up with, but off-hand, since I'm using a ratio (as stated above), I would expect to get 56% copper-fin coverage, where yours is 50%. I gotta run those numbers...
I haven't had any luck (preliminary) in finding a blade width of 0.8, much less 0.6 .
I'm considering a photo-etching solution, but I can't quite visualize it yet.
