Printed circuit board with radio frequency identification and production method thereof

Abstract

The invention discloses a printed circuit board with a radio frequency identification, comprising a printed circuit board, a radio frequency identification chip, a radio frequency identification antenna and conductive adhesive, wherein the radio frequency identification chip is arranged on the printed circuit board; the radio frequency identification antenna is printed on the printed circuit board; an antenna pin is arranged at one side of the radio frequency identification antenna; and the pin antenna is closely connected with a connecting port of the radio frequency identification chip by the conductive adhesive. The production method comprises the following steps of: firstly, printing the radio frequency identification antenna on the printed circuit board; secondly, coating an insulating layer at the part of the radio frequency identification antenna, which corresponds to a jumper wire; thirdly, printing the jumper wire and respectively connecting two ends of the jumper wire with the head and the tail of the radio frequency identification antenna; fourthly, coating the conductive adhesive on the antenna pin by adhesive dispensing equipment; fifthly, turning over the radio frequency identification chip to be connected with the antenna pin; sixthly, hot pressing the conductive adhesive and curing the conductive adhesive; and seventhly, testing the qualified rate. By using the invention, the labor cost can be saved, the work accuracy can be improved, the quality of products can be ensured, the processing can be accelerated and the logistics dynamic can be effectively tracked.
