Application of wet film - Engineering Technical - PCBway

Dec 13, 2013 Wet film in the fine lines of the inner process of making the pass rate is greatly improved, compared with the dry material cost savings of 20%. Wet developing faster 30%, the etch rate can be increased by 10-20%, increase the speed of faded film, thus saving energy, improve equipment utilization, and ultimately reduce the cost.

Wet and Dry Film Thickness Formulae

From the above equations, wet film thickness (WFT) may be easily calculated for a specified dry film thickness (DFT). If the wet film thickness is known the coverage of a coating in square feet per gallon may be calculated using the following formula: Coverage in 'Square Feet Per Gallon' = 1604.17 Divided By the 'Wet Film Thickness in MILS.

Dry Film Thickness / Wet Film Thickness x 100 = Volume Solid shown as a percentage (%) again using the above numbers it would be as follows; 90 DFT / 150 WFT x 100 = 60% VS. m2 per ltr = 10 x VS (%) / DFT in microns.

Digital Versus Wet Film Photographic Imaging

Digital Versus Wet Film Photographic Imaging

Jan 27, 2014 Film grain is another impediment to high quality in wet film images. Many films which on paper have respectably low RMS grain size are disappointing in practice. While the RMS grain value may be low, the statistical properties of the grain may still be such, that grain will be present at sizes comparable to a pixel and impair the image.

Print Sharpness Scanned Negative vs. Wet Print

Nov 15, 2017 Sure it holds the film flatter, but it diffuses the light some. The advantage to a wet print is that if done properly, you can get away with less actual sharpness, but more apparent sharpness. It may not look as sharp close up, but it can look sharper from further away. Also, a wet print will stay truer to the original negative.

Sep 18, 2017 Wet film thickness is the thickness of wet paint or any coating film that is liquid based. Wet thickness is at its peak right after the application of coating. It decreases once volatiles and solvents from the coating film undergo evaporation. Measuring wet film thickness is necessary to identify the amount of material that needs to be applied ...
