摘要

The American twin-plant industry along the El Paso, Texas and Cd. Juarez, Mexico border is rapidly changing the traditional role of an operator involved in manual assembly tasks. In the electronics assembly industry in particular, operators are faced with challenges that come along with newer technology (e.g. component miniaturization, etc.). The electronics assembly industries in the U.S. twin-plants in Mexico are also introducing a higher level of operator involvement in the productionprocesses. The physiological, biomechanical and cognitive aspects of manual electronics assembly have thus been gaining the interest of the twin-plant or maquiladora industry, as a cost reduction, and throughput and yield improvement tool. These ergonomic aspects are also of concern to the Mexican Department of Labor, who is responsible for occupational safety policy and administration. This has resulted in the concurrent interest of identifying and minimizing the ergonomic risk factors that affect throughput and yield and minimize or eliminate occupational disorder risks. In spite of the manufacturing automation available (e.g., automated glue dispensers, computer vision systems, etc. in the area of electronics assembly), it is expected that human assembly is likely to persist due to the high flexibility that characterizes human performance. This paper addresses Mexican occupational safety low, and the physiological, biomechanical and cognitive risk factors that affect throughput and yield. A case study of an electronics assembler in the maquiladora industry that successfully undertook an ergonomic re-design is presented. The results indicate that through very modest expenditure, the impact of these risk factors (identified by Mexican occupational policy) on the electronics assembly workforce was significantly minimized, with impressive throughput and yield gains.
