Touch screen analysis of main components and use Paste

&Nbsp;    touch-screen silver main components and analysis of main material
touch screen is adhesive, conductive fillers, solvents and additives. Adhesive of epoxy-resin, acrylic resin, alkyd resin, Melamine-Formaldehyde resins, polyurethane resins, phenolic resins, vinyl chloride-vinyl acetate copolymer resin. Conductive filler in conductive and that is silver and copper powder, occasionally with graphite, dust, carbon black (now have special conductive carbon black), nickel, carbon fiber powder. Call screen which is used to dissolve the resin solvent paste by boiling point (120-230 c) solvents. Finally, the conductive silver paste can also be added dispersant, slip agents and coupling agents and other additives.
the touch screen pastes are mainly used for doing it? in General, the main use of conductive silver paste include:
1. electronic circuit board industry. Conductive silver paste applied welding electrical and thermal conductivity adhesive curing at room temperature, such as quartz crystal, Piezoelectric ceramic, potentiometers, Pyroelectric infrared detectors, Flash and repair of shielding, circuit, could also be applied to radio instrumentation industry, conductive bonding also can replace paste to achieve conductive adhesive.
2. screen printing industry. Due to the conductive silver paste with low curing temperature, very high bonding strength, stable electrical performance characteristics, so it is suitable for screen printing. BACK
