- 1. Domes Manufacturers And Suppliers In Singapore
- 2. Polytech manufactures poly dome and metal dome that are used in many kinds of applications. Poly dome is created with a process used on polyester film under conditions of hot temperature and high pressure at the same time, known as hot pressing. The end product resulted with a switch feature widely used as control switches, keypads, and others.
- 3. The basic poly dome configuration is designed with a layer of silicone adhesive that is 0.08 millimeter in thickness. This is followed by the PET dome that is 0.125 millimeter in thickness. A spacer that is between 0.1 to 0.125 millimeters in thickness is placed next. The contact resistant is placed just underneath the PET dome layer and the material used is dependent on the product itself.
- 4. The basic configuration can be extended to be incorporated into a polyester circuitry layer that is between 0.1 to 0.125 millimeters in thickness. The advantage of poly dome is a tactile feel with a comparable short actuation. Poly dome constitutes the fundamental design for front panel and polyester circuitry products. Some applications of poly dome used in the telecommunication industry are building poly dome into electroluminescent (EL) and light-emitting diode (LED) and then fitting them together onto printed circuit board (PCB) or silicone rubber key mat.
- 5. Poly dome is used in remote controllers for audio and visual products with contact made of plastic actuators or rubber key mats. Graphic overlay can also be applied onto poly dome to form a variety of applications in household electronic appliances such as rice cooker, washing machine, coffee maker, vacuum cleaner, vacuum thermal flask, microwave oven and compact remote control.
- 6. Polytech manufactures its metal dome with a thickness of 0.075 millimeter made of stainless steel. The metal dome can be placed on printed circuit board using pressure- sensitive adhesive film. Metal dome has high rebound force and is able to provide more tactile feeling with shorter actuation compared with poly dome. This allows users to have a good clicking feel. The metal dome can be plated with various types of materials such as nickel, silver, copper, or gold. A metal dome array comprises of metal domes taped together adhesive.
- 7. Metal dome arrays can be assembled onto flexible printed circuit (FPC), printed circuit board (PCB) or front panel. The flexible printed circuit can be built into electroluminescent(EL), light-emitting diode (LED) and liquid-crystal display (LCD)The characteristics of the metal dome are slim in thickness, light in weight and ability to operate under temperatures as high as 85 degree Celsius or as low as negative 55 degree Celsius.
- 8. They are suitable to be used as electrical contact where its long mechanical life cycle can typically reach around one million times. The different kinds of metal dome available are circle shaped, triangle shaped and oblong shaped. Moreover, Polytech is able to customize the metal dome to cater for clients who require special shapes or sizes for their specific product specifications. Some applications for metal dome arrays are mobile phones, MP3 player, digital cameras, GPS devices, cordless phone and other electronic devices.
