摘要

The study aimed at reducing Printed Circuit Assembly (PCA) manufacturing problems, such as high production and customer rejects, occupational ill health and high labour content. Subjective assessments and direct observations were made in the manufacturing plant. The major problems were due to the Surface Mounted Technology Component Placement (SMTCP), the Manual Soldering (MS) and the Manual Cleaning (MC) processes. Previously, the SMTCP machines had difficulty in placing the Integrated Circuits (ICs) onto the pads due to the errors in the pad design, causing IC misalignment. The operators experienced difficulty in performing too much MS, which caused 13% component damage. The MC of the soldered areas of the PCAs caused headaches due to the smell of the solvent. Ergonomic recommendations were given and follow-up studies were conducted. The PCAs were redesigned to correct the pad design errors and to allow more components to be machine-soldered. This also reduced the labour content and the number of components being damaged during MS. Local suction chutes were installed to remove the MS fumes and solvent vapours. These interventions reduced the production rejects, improved productivity, improved occupational health and safety (OHS) and saved dollarUS 581,495 on rejection cost per annum.
