| SMD-series, a surface mount device packaged by printed circuit board with CU terminals arrayed and
polyimide film overlaid, is a new concept designed to seek full automation of metal dome switch set
assembly process. As a thin and slim package-type SMD switch, SMD-series is dust-proof and water-proof
and very efficient for high-density design of various portable devices like mobile phone and mp3, providing
excellent cost-effective A/S workability as well as such design advantages.
Product lineup is standardized to
Φ 3.5, Φ 4.0 & Φ 4.5 size, all of which provide the same tactile feel quality and life time over 500K cycles. |
