Instead of silver palladium powder, nickel-based conductor powder for electronic thick film atomizin


Thick film technology is to deposit conductive paste, resistive paste or dielectric paste on the ceramic substrate by screen printing, and then burn at high temperature to form a firmly adhered film on the substrate. After successive repetitions, a circuit of a multilayer interconnect structure is formed, which may contain integrated resistors, capacitors or inductors.


Due to the high stability and excellent performance of thick film technology, it was mainly used in military, aerospace and test equipment in the early stage. With the continuous development of technology, thick film technology is widely used in automobile (engine control system, safety anti-lock braking system), communication engineering (program-controlled switch user circuit, micro power amplifier), medical equipment and consumer electronics and other fields. Electronic ceramic atomizing cores and ceramic heating plates, as new things that have developed rapidly in recent years, have also carried out in-depth research and application of thick film printing technology. Its characteristics such as fast response speed, high mechanical strength, strong thermal conversion ability, low-voltage start-up, and durable and stable performance are also widely recognized by manufacturers.

Thick film paste is mainly divided into three types: conductor paste, resistance paste and insulating paste. The paste is generally composed of precious metal and low melting point glass. When making the slurry, pay attention to the material, viscosity and expansion coefficient of the slurry. The paste used for printing thick film circuits is basically composed of precious metals such as gold, silver, platinum, and palladium. With the gradual introduction of the national standard for electronic cigarettes, the barbaric growth of the electronic atomization product market in the past will be controlled, and the profits and sales of electronic atomization products will decline sharply in the short term. Manufacturers will consider more optimization and improvement in terms of product cost. Precious metal heating paste, as a high-cost raw material, is also the main object of manufacturer optimization. The R&D personnel hope to find a suitable base metal raw material, which can not only meet the needs of reducing costs, but also ensure the stable effect of heating of the atomizing core. At this time, nickel-based conductor powder came into being.


Foshan Transform Material Technology has finally developed a nickel-based conductor powder that can stably generate heat in the thick-film atomizing core by adjusting the

composition of nickel-based superalloys and conducting repeated tests

with electronic cigarette thick-film atomizing core manufacturers. At present,

the conductor powder has been used in the conventional production of ceramic atomizing

cores, and the end products are exported to overseas.

Product Features


1. Low cost, more common precious metal silver palladium alloy and other materials have a greater cost advantage


2. The resistance value is moderate, and the test data shows that the resistance value is stable around 1Ω


3. The heating is stable, and the thick film heating element can be repeatedly heated for more than 400 times by the customer's on-site test


4. The printing efficiency is high, the particle size is thicker than the common nanometer and submicrometer products, and the single printing layer thickness is larger, which effectively shortens the processing time.


5. High temperature creep resistance, can resist repeated impact of the standard voltage of the atomizing core, high durability
