Sony reduces defects in assembly

Published: 13-Oct-2003


The intricate assembly stage of high value electronics products brings a number of challenges. The camera division at Sony Manufacturing in South Wales has been researching methods of reducing a number of assembly-related problems that involved contamination being brought into the area from external warehouses. Sony has used Dycem's range of contamination control floor coverings to provide the optimum solution, as well as peace of mind. Dycem claims that the flooring is 99% effective in preventing both feet and wheel-borne contamination. Since installing this flooring at entrances and exits to and from the camera division assembly area, Sony has seen its particle counts plummet from 12 million particles per cubic ft to 8 million. The large particle incidence (25 microns and above) has also significantly reduced. The former class 10,000 cleanroom now meets class 1,000 criteria. In addition, all operatives take at least three footsteps on the flooring before entering the clean area.
