Ceres Security Ink Screen Printing Conduction Ink

Introduction: 
Electrically conductive printing ink is a kind of inks for dispersing a conductive material (gold, silver, copper, and carbon) in the linked compound prepared paste, commonly known as paste inks. Nature has a certain degree of electrical conductivity, as printed conductive or conductive line point of use. Kim Department of conductive ink, silver conductive ink, copper-based conductive ink, carbon-based conductive ink, etc., have reached practical, for printed circuit, electrodes, electroplating bottom, the keyboard contacts, resistors and other printed materials.

Type:

Powder chemical stability, good conductivity, but expensive, use is limited to thick film integrated circuits. 
Silver conductive ink. Used extensively for printing conductive membrane switch. When printing materials as polyester, can be dispersed into the polyester resin silver compound link, you can make a paste of conductive ink. When performing a dry ink film, the resistance value increases, preferably far-infrared drying in a dryer under 120 ~ 130 °C. 
Copper than silver inexpensive, but the disadvantage of easily oxidized. Copper are often used after oxidation treatment, the use of this ink printed circuit less susceptible to oxidation, but the drawback is a high temperature treatment, anti-oxidation effect will be lost. 
Carbon-based conductive ink. Carbon-based filler used in the conductive ink and a conductive channel black, acetylene black, furnace carbon black and graphite, the resistance varies with the type bits. Used for film sheet resistance of the switch and printing, the former mostly printed on polyester substrate, so it the same silver conductive inks, polyester resin binders based inks.

RFID antennas Printed :

With the rapid spread of RFID technology applications, some large ink manufacturers also timely introduction of new conductive ink, to further promote the development of the RFID market. We can say that one of the key factors driving the RFID market is gradually moving towards the success of the successful development of conductive ink. 
A conductive ink is dispersed in a conductive composite material formed of a metal compound linked conductive fine particles (silver, copper, carbon, usually silver), and then printed onto the substrate, acts as the wire, and the resistance of the antenna. The ink is printed on a flexible or rigid material (paper, PVC, PE, etc.) can be made on a printed circuit. After drying the conductive ink, the distance between the conductive particles becomes small, electrons move freely along the electric field formed in the current direction, with good conductivity, may receive special RFID radio frequency signals. For the purpose of printing RFID tags built-in antenna, a good conductive ink formulations, requires a good printability, ink after printing with strong adhesion, low resistivity, low curing temperature, conductivity and stability characteristics. 
According to market research firm NanoMarkets analyzes, the conductive ink market will develop into a very large industry in 2015, conductive inks will be the current market value of three times, reaching $ 2.4 billion. Due to attractive market potential, ink manufacturers flocked conductive inks have started to get involved in business, hoping to which slice.

Application:
Printing conductive ink on the conductive means substrates, so as to have a current conducting capacity and elimination of electrostatic charge accumulated ink is generally printed on plastic, glass, ceramics, cardboard or other non-conductive substrates. Printing method is very broad, such as screen printing, letterpress printing, flexo printing, gravure printing and offset printing etc. can be used. Can be selected according to the requirements of the thickness of different printing methods, different thickness of the resistance, solder resistance and abrasion resistance, are also different. This ink has a thick paste and resin type two. The former is a high-temperature glass frit firing type adhesives, synthetic resin as a binder which is a low-temperature drying or radiation (UV, EB) curable screen printing ink.
