To get a wavelength of 365 nm, the electrical characteristic of Ag films was enhanced when the silver film was photo-sintered at greater light intensity and for longer irradiation duration. In unique, considerable reduction with the resistivity was observed on the samples irradiated using a light intensity of 300 mW/cm2 . The minimum resistivity of five.44 10-6 m (just about 3 times compared to worth of bulk silver) was obtained in the optimum photo-sintering circumstances of 300 mW/cm2 and 50 min. Equivalent outcomes have been obtained for any wavelength of 385 nm, even though the resistivity exhibited larger values in all samples, suggesting the shorter wavelength of UV-LED are a lot more powerful for improved electrical efficiency. The minimum resistivity of 5.44 10-6 m (sheet resistance of 72.six m/sq), comparable worth from Ag films photo-sintered with IPL [55], was obtained from the optimum photo-sintering situations (300 mW/cm2 and 50 min). Comparing to values of thermally sintered silver film (Figure five), the films irradiated using the UV-LED modules appeared to have much better electrical conduction, regardless of the wavelength. The significant modifications inside the electrical resistivity of Ag thin films according to the sintering situations are attributed to many motives. Dziedzic et al. [56] recommended that when the curing temperature got higher, the mass and thickness from the conductive pillars in the carbon/polyesterimide (PEI) composite films decreased, resulting in lower electrical resistance. Even so, there was no significant distinction within the thickness of Ag films depending on the curing temperature or the sintering methods (thermal and photo-sintering), though the as-pre.
