Abstract

See full text

A slot die shim for use with a slot die, the slot die shim including a first channel configured to receive a first coating, a second channel configured to receive a second coating, and a third channel configured to receive a third coating. The slot die shim simultaneously dispenses the first coating through the first channel, the second coating through the second channel, and the third coating through the third channel onto a substrate. The coatings can be applied at different flow rates and include different test reagents. A vacuum force is applied to the first, second, and third coatings to control a width and a thickness of each of the coatings and a gap or distance between the coatings. The first, second, and third coatings are placed near one another or directly in contact with one another to minimize the area required for the coatings.
