Talk:Spin coating

no heading

It is said in this page that spin coating will "...spread the fluid by centrifugal force." Since the page describing centrifugal force clearly indicates that this force is imaginary in the sense that it is being used in on the spin coating page, I recommend that the term "centrifugal force" is removed from the description of spin coating (since there is no such force).

That is nonsense. The term centrifugal force makes a lot of explanations much simpler. "Imaginary" is NOT the same as "there is no such thing", and it also doesn´t mean "sloppy". --Maxus96 (talk) 21:59, 4 May 2009 (UTC)

It's not nonsense. There is no such thing as an "outward force" within a spinning object, and so to say that Spin Coating spreads the fluid by centrifugal force is misleading. This is a scientific article, and being accurate is important. It would also make explanations a lot easier if we just said "the stuff just gets spread around 'cuz its spinning and stuff," but we don't because accuracy is important. Also, IMO, you're a nutjob if you say that just because something is imaginary doesn't mean "there is no such thing," since that's the definition of imaginary. Otherwise, according to you, something "exists" merely by thinking about it. Indowiz (talk) 03:02, 10 May 2009 (UTC)

Insulting me, are you? Many thanks. --Maxus96 (talk) 01:38, 17 May 2016 (UTC)

Not this again! The fluid is rotating, it experiences an outward force in its rotating frame of reference; centrifugal force. Nothing imaginary about it. What I came here to find out was "why does a spin coater produce a uniform film thickness?". --Adx (talk) 16:59, 10 July 2009 (UTC)

spinning frequency

20-80 Hz? Shouldn't that be RPM not Hz? —Preceding unsigned comment added by 210.19.78.34 (talk) 01:15, 16 April 2008 (UTC)

Hz x 60 = RPM --Maxus96 (talk) 21:59, 4 May 2009 (UTC)

Most often poor quality, hazy or "orange peel" coatings (coatings which peel away from the plate), are the result of moisture absorption due to environmental humidity.

orange peel altough caused by humidity can lso be cause by inappropriate solvent or solvent - polymer concentration - but need verification. more important is that orange peel is not a caoting that "peels" but orange peel (skin0 like texture caused by the reasons mentioned, harming uniformity witch is the process main application!--79.176.15.205 (talk) 02:41, 23 August 2008 (UTC)

Wikifying jargon, need some experts to write articles

The tutorial section was full of unreferenced jargon. It is useful to wikify this stuff for people with a general interest in this article, who may not know what these chemicals and tools are. There are some words which I've linked to articles that don't yet exist. Someone with more knowledge in the field should create these:

• 1,2,3-trichloropropane
• Disperse Red
• DANS
• lint free (would be useful in other articles such as optics and photography)

Rotation per second?

Isn't rotation per minute more commonly used? The lead quotes RPS figures and I never encountered anything but spinners with RPM. 130.236.150.142 (talk) 12:57, 16 August 2010 (UTC)

In experimental physics, it is common to use "Hertz" for the speed of a rotating setup, e.g. in MAS NMR. The equivalent "RPS" unit is new to me, too. --Maxus96 (talk) 01:43, 17 May 2016 (UTC)

Spin curve

I think it would be nice to add a spin curve, to give the reader an idea what rotation speeds are used and what thickness that will give.

Can someone find a rights-free one, or make one themselves? Sdk16420 (talk) 14:06, 11 May 2015 (UTC)
