Apple and other technology companies that are introducing a wave of touch-screen tablets face an ambitious challenge.
In general, higher CVintra of layer thickness were found on the centre bands in comparison with the tablet faces.
No increase or decrease in layer thickness – as described in the literature – was found towards the edges of the tablet face.
The analysis of the DoE model revealed that the run duration had the highest influence on the CVintra on the tablet faces.
Different measures of intra-tablet uniformity were investigated: the average thickness on the individual tablet faces, spatial variation in layer thickness over the tablet surface, and the coefficient of variation (CVintra).
Data analysis revealed that the process parameters in the investigated parameter space had hardly any influence on the difference in layer thickness of the tablet faces and centre band.
"As much as BoomTown likes a good computer tablet face-off," she writes, "sources with knowledge of the situation said that Microsoft CEO Steve Ballmer will not be whipping out the secret slate PC".
It also debuted a "robotic butler" with a tablet face back at CES in January that seemed more proof of concept than shipping product — though UBTECH has promised a broad 2019 release date.
Here I was, a longstanding holdout against the trend of tablets, face-to-screen with my first tablet.
Google (and Asus) have no such guarantee, and the same problems that the generic Google Android tablets face.
