In the thick film process, the individual layer is deposited by screen printing. Each screen mesh may differ according to requiring ink deposit thickness. Four screen mesh counts of 100, 150, 200, and 305 threads per inch are chosen and a designed test figure is exposed on them for printing experiment to measure the ink deposit thickness. These variables affect as much as around 50% compared with the theoretical ink volume listed by the mesh manufacturer and each variable has different influence on the thickness.
