52 The PCB Magazine • February 2015 discussions above it is apparent that Ni presents some difficulties when considering its suitabil- ity within the scope of future requirements. The target of this article is to highlight the superior- ity of the EPAG process in ascertaining the goals of the future. If this article has not been con- vincing enough there will be more discussion on this topic at the iMAPS 2015 in Orlando, Florida in March. PCB Figure 9: the characteristics of prior art tCB compared to EPAG. (the highlights are in green.) Figure 10: this demonstrates initial results achieved at the Georgia Institute of technology (tCB at 190C – 3s – 365MPa with perfect electri- cal yield [1-2Ω]). rick nichols is global product manager, selective finishing, at Atotech deutschland Gmbh. he may be reached by clicking here. researchers at Japan's national Institute for Ma- terials Science revealed that improvements should soon be expected in the manufacture of transistors that can be used to make flexible, paper-thin com- puter screens. the scientists reviewed the latest develop- ments in research on photoactive organic field- effect transistors, devices that incorporate organic semi-conductors, amplify weak electronic signals, and either emit or receive light. Organic field-effect transistors (OFEts) were developed to produce low-cost, large-area elec- tronics, such as printable and/or flexible electronic devices. Progress has been made in the develop- ment of light-emitting organic field-effect transistors (LE-OFEts) since they first appeared in 2003. research in this area has resulted in advances in the manufacture of novel organic photonics ap- plications using cost-effective approaches. Light emission efficiency and brightness of these transis- tors will soon improve. And the production of new display technologies is expected to be the result of further research.
