A study by Yeow [22] concentrated on improving productivity as well as health and safety of workers in a printed circuit assembly (PCA) factory. The improvement involved the use of an ergonomically designed workstation with other ergonomic intervention such as clear segregation of tested and untested boards to prevent mix-up and retraining of operators by more qualified trainers. This had resulted in an improvement in quality and productivity of the workers, reduction in rejection rate as well as an increase in the revenue. The use of an ergonomically designed workstation and better structured processes along with other features, such as improved lighting, shelves and containers for parts and display boards, had helped and solved the problems of assembly processes at a German company [23].
