I've been looking for the thin film substrate. If you know any vendor might have it, I would be very grateful.
The film should be as smooth as possible. Ideally the RMS roughness is about 5-10nm
Could u please more specific? I read some other explaination, but still I don't get it
Added after 1 minutes:
Oh by the way, I have ome more question: Is it easier to make DC current source or DC voltage source. THanks
of comparatively little physical weight or density; "a light load"; "magnesium is a light metal--having a specific gravity of 1.74 at 20 degrees C"
hehe
From memory, the equation editor in Word isn't very good - but the last time I used it was YEARS ago so it may have improved.
WordPerfect was better. In fact, back in my uni days (early 90s) one of the things I did in a holiday job was lay out a maths textbook for uni students in WordPerfect...
A DC voltage source develops 10 V DC at its output terminals. A DC current
source that you found at the flea market develops 10 A maximum when properly
loaded. Is the first device a high-resistance device, or a low-resistance one? How
about the second device?
