Description
Technical field
The utility model belongs to microelectronic industry sealed in unit manufacturing technology field, relates to a kind of radio electronic label INLAY encapsulation process mid point glue process section point offset plate thermostatically-controlled equipment.
Background technology
RFID (Radio Frequency Identification) less radio-frequency identification also claims " radio electronic label ", and it is a kind of contactless automatic identification technology of radio communication realization that utilizes.Radio electronic label have small and exquisite frivolous, capacity is big, the life-span is long, characteristics such as reusable, support fast reading and writing, non-visual recognition, move identification, multiple goal identification, accurately locate and technology such as tracking.The coming years, along with the China RFID application technology constantly improve and ripe, and the reduction of RFID application technology cost of goods manifactured, its product will be widely used in fields such as Chinese safety encipher, logistics, manufacturing, communications and transportation, communication, retail and military affairs.
The radio electronic label of a telotism is made up of RFID chip and antenna, must firmly effectively connect between chip and the antenna, and to ensure its electric property and physical reliability, such label is referred to as INLAY.
In the INLAY encapsulation process, comprise 6 procedures: antenna unreels, some glue, and bonding die, hot pressing detects the antenna rolling.The point glue process is one of gordian technique of INLAY encapsulation.In this section operation with the conducting resinl of certain viscosity, be coated on the electrode pad position of antenna accurately and fast by the precise glue dispensing control device, purpose is in the subsequent handling RFID chip to be bonded on the electrode pad of antenna effectively, and then pass through hot pressing process, the crushing conductive particle, realize being electrically connected of RFID chip and antenna, and further solidify viscose, strengthen physical connection.
