Electronics manufacturing is undergoing rapid transformation with advances towards the high intelligence, higher integration and nanodevices. The surface and interfacial related tribological issues during the electronic fabrication process have become one of the predominant factors affecting the production efficiency, products quality and performance of devices because the miniscule size of the newly developed devices is towards atomic scale. It poses a significant challenge for us to comprehensively understand the role of tribology during the electronic fabrication. The review paper proposes the concept of electronics manufacturing tribology. Afterwards, the inseparable development history of electronics manufacturing and tribology has been looked back. The important role of tribology on promoting the development of electronics manufacturing has been elaborated in detail. The review attempts to highlight the future opportunities and challenges of electronics manufacturing tribology in the last part. It is hoped that such a review will throw light on the future development of high-performance electronics manufacturing and enrich the micro- & nano- tribology fundamentals as well.

Trackless rubber-tyerd vehicles are the core equipment for auxiliary transportation in inclined-shaft coal mines, and the rationality of their routes plays the direct impact on operation safety and energy consumption. Rich studies have been done on scheduling rubber-tyerd vehicles driven by diesel oil, however, less works are for electric trackless rubber-tyred vehicles. Furthermore, energy consumption of vehicles gives no consideration on the impact of complex roadway and traffic rules on driving, especially the limited cruising ability of electric trackless rubber-tyred vehichles (TRVs). To address this issue, an energy consumption model of an electric trackless rubber-tyred vehicle is formulated, in which the effects from total mass, speed profiles, slope of roadways, and energy management mode are all considered. Following that, a low-carbon routing model of electric trackless rubber-tyred vehicles is built to minimize the total energy consumption under the constraint of vehicle avoidance, allowable load, and endurance power. As a problem-solver, an improved artificial bee colony algorithm is put forward. More especially, an adaptive neighborhood search is designed to guide employed bees to select appropriate operator in a specific space. In order to assign onlookers to some promising food sources reasonably, their selection probability is adaptively adjusted. For a stagnant food source, a knowledge-driven initialization is developed to generate a feasible substitute. The experimental results on four real-world instances indicate that improved artificial bee colony algorithm (IABC) outperforms other comparative algorithms and the special designs in its three phases effectively avoid premature convergence and speed up convergence.
