Abstract

The invention discloses a manufacturing method of a metal-directly-plated RFID (radio frequency identification) electronic tag antenna. The antenna is formed by sequentially arranging a pre-coating layer, an antenna pattern layer, a metal-directly-plated layer and a surface coating layer. The manufacturing method comprises the following steps of pre-coating a base material, designing the antenna, preparing a pattern anilox roller, printing an anilox roller pattern, directly plating metal in vacuum, coating a surface coating and the like. Due to the fact that the antenna is directly formed by melting and evaporating a metal raw material in vacuum at high temperature, and evaporating the metal raw material onto the base material according to the designed antenna pattern, and subsequent manufacturing steps such as aluminum washing or hot stamping are not required, the production process is simplified. The manufacturing method of the metal-directly-plated RFID electronic tag antenna is capable of reducing radio frequency antenna manufacturing cost, environment-friendly, simple in process and high in production efficiency, and the defects of high cost, environment pollution and the like of the current electronic tag antenna manufacturing method are overcome.

Description

technical field [0001] The invention relates to an antenna manufacturing method, in particular to a radio frequency identification (RFID) electronic tag antenna manufacturing method. Background technique [0002] Radio frequency identification card (RFID, radio frequency identification) is a typical non-contact IC card, which uses wireless communication technology to realize data exchange between the system and the IC card. [0003] RFID tags are characterized by small size, large capacity, long life, and reusability. They can realize non-visual identification, no manual intervention, fast reading and writing, mobile identification, multi-target identification, positioning and long-term tracking management. RFID technology has been widely used in the Internet, communications, sales, logistics, manufacturing, tourism, management, public information services and other industries, improving management and work efficiency. It is estimated that more than 400 billion RFID tags wi...
