Abstract

The invention discloses a method for preparing printing electron by adopting catalytic type nano particles. The method adopts the following steps of: printing resin on a substrate, printing the catalytic type nano particles onto the resin after the resin is solidified or half solidified to form a circuit with electric conductivity and catalytic property, then carrying out chemical plating treatment on the circuit and plating a metal layer with high electric conductivity so as to obtain an electronic circuit. The printing electron prepared by the method lowers the processing cost greatly, the obtained electronic circuit has the advantages of high electric conductivity, high stability and the like, and the application of electron for printing and manufacturing in a plurality of fields of a battery, a display, a sensor, an RFID tag, an interactive package, a solar panel, a loudspeaker and the like can be pushed.

Description

technical field [0001] The invention relates to a processing method for printed electronics, in particular to a method for preparing printed electronics by using catalytic nanoparticles. Background technique [0002] The method of printing electronics is an electronic circuit processing method that has emerged in recent years. Different from the traditional "subtractive" process of printed circuit boards, this method uses the "additive" process to print electronics and circuits directly on the surface of the substrate to be printed. This process not only reduces the cumbersome processing procedures, but also facilitates the processing of electronic circuits with tiny dimensions. [0003] The current processing technology is to mix highly conductive nanoparticles with resin and print them directly on the circuit substrate to form electronics (circuits). Copper and silver nanoparticles are usually used as the conductive medium, but the nano-copper is easily oxidized and the ...
