The Research and Development of Waterpro of Mobile Phone

[[abstract]]現今市售的防水手機是利用防水膠條來進行防水，這類手機需隨時將卡榫緊閉， 才可達到防水效能，但由於膠條長時間的使用下會失去彈性，使得手機喪失防水功能， 若需手機擁有防水功能的話，則必須定期去保養及更換防水膠條。如果一般手機是使 用噴塗防水膠，進行防潑水，但這種防水膠需 2~3個月再重新噴塗，售價約 1400~1500 元不等。此外，一般防水膠噴塗過程中無法將組件中的導體接腳和導線均勻包覆，若 將此組件放入水中，則會造成短路現象。本計畫預計開發真空鍍膜防水手機，利用 Parylene 化學氣相沉積技術，塗層分子是堆疊方式均勻披覆在所有組件上，使組件上 的導體接腳和導線可有效的受到防護。目前全球智慧型手機平均銷售價格約 1萬元， 防水鍍膜之售價預估為 800元，2013年第一季台灣手機市場總量為 232萬支，若初期 能爭取到 5%的訂單，每季將有 9280萬之產值。[[abstract]]Waterproof mobile phone available today is the use of waterproof rubber band for waterproof; these phones need to keep the latch closed. Besides, after long time usage, the waterproof rubber band will lose elasticity, making the loss of waterproof function. To achieve the long time reliability of waterproof function, it must replace regularly the waterproof rubber band. If the waterproof glue is used for waterproof mobile phone, waterproof glue will loss function after 2 to 3 months and it should be re-spraying, the cost ranging from about NT1400 to 1500. In addition, during the waterproof glue spraying process, it can not conformal cover the pin assemblies and wire conductor, if this component dip into the water, it will cause a short circuit. This project is to develop the parylene coating for waterproof mobile phone, by using the chemical Parylene vapor deposition techniques, the coating molecules are uniformly coated in a stacked manner on all components, the assembly of the conductor pin and the wire protection can be effective. The current global smartphone average selling price is about NT10,000, the price of parylene waterproof coating is estimated about NT800. Taiwan's total mobile phone market in the first quarter of 2013 is about 2.32 million, if the new design can win 5% of market share; there will be 92.8 million of value created every quarter.[[note]]MOST103-2622-E327-004-CC
