6. Digital Printing or Silk screen printing available.
Membrane switch flexible polycarbonate or polyester film printed with conductive paste made of the switch contact circuit is a contact switch. <o:p>
Membrane switch has the advantage of the whole flat, thin shape, quality, small, dust-proof, good, good water resistance, is a semi-enclosed structure. In addition, the panel design, and great freedom of choice of colors. Positive range of applications of desktop computers, copiers, fax machines, toys, square computer, word processor and other areas of expansion.
Membrane switch production process are generally: <o:p>
Electrode Board to make silk screen printing plate → → → drying → Silver Screen Printing Screen Printing carbon seminal → drying → Pressing → Screen Printing → panel assembly. <o:p>
The following brief membrane switch materials and screen printing process. <o:p>
1. Substrate <o:p>
For the production of membrane switch panel substrate of the following: <o:p>
(1) polycarbonate film <o:p>
Polycarbonate film great temperature range (-135 ~ 135 ºC), when the temperature or humidity changes, the performance of this material changed little, from 100 to ensure the panel can be various types of equipment under a variety of harsh environment use. <o:p>
(2) PVC film <o:p>
Poor heat resistance, especially in high temperature conditions, the softening temperature of 59 ºC, less flexible polycarbonate film good. But it has a high elongation (130%), but also because of its low price, it is suitable for use in the general conditions. <o:p>
(3) polyester film <o:p>
Flexibility and heat resistance are good, the price range of between polycarbonate film and PVC film. But its hard to process into films matt type surface texture, often isolated and the transparent sheet, while the vast majority of the surface of polyester film of plastic printing ink can not get satisfactory results, generally requires the use of a particular special ink. <o:p>
(4) Polyethylene film <o:p>
Polyethylene film with excellent physical properties and chemical properties, and ability many chemicals, such as alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, esters, ketones and alcohol ether etc. However, the higher the price of polyethylene film. <o:p>
