“…However, in the absence of real-time diagnosis, factors such as an uneven mixture of polymer films or quality issues associated with the laser trimming system may result in problems when treating RAM modules. In this case, factors influencing stability, such as parameters of the laser system, uniformity of overlap rate of the cutting path affecting TCR variance in the laser trimming quality (Pietro et al, 2000), the measuring instrument with adjustments of the probe holder, and the uniformity of the polymer film carbon resistors in the screen-printing technology, must be analyzed.…”

“…Pietro et al [144] have developed a 3-D transient heat transfer model for the prediction of kerf geometry considering the exothermic reaction energy. Kim et al [145] have developed a 2-D FEM based heat transfer model for both steady state and transient conditions.…”

“…However, it is a complex material removal process in which, the geometric quality of fabricated parts and components significantly depends on optimized process parameters related to laser, optics, workpart material, and the motion system (Vatsya et al 2005;Bordatchev and Nikumb 2003;Di Pietro et al 2000;Chang et al 1998). Figure 6 shows line cutting on a 25 lm thick nickel foil with passes varying from 1 to 19 at focus point.…”
