The radio frequency identification technology is one of the most promising and applying information technologies in the 21th century, therefore, it is very meaningful to do the research and development of RFID tag-package equipments. A RFID tag-package equipment includes five modules, they are web-conveyed module, testing module, dispensing module, flip-chip bonding module, and hot pressing module. As a necessary process of the equipment, the function of hot pressing is to provide the mechanic and electric connection of chip and antenna. This article mainly states that designing the hot pressing machine, analyzing the thermal situation of hot pressing head while working and testing the performance of the machine.Firstly, comparing with the electronic packaging processing, the most suitable one is chosen. Then the design requirement of the hot pressing machine, the working procedure and the entire proposal is created according to the design figure of the equipment.Secondly, two kind of schemes are mapped out on the basis of the requirement of thermal and pressure precise control, therefore, the structural design and the selection of main driver parts are worked out through the two different ways separately, which are spring structure and cylinder structure. Then the structure of hot pressing head is selected by comparing the two schemes.Thirdly, To begin with the CAD model simplified, it sets up the finite element model and makes meshing. And the thermal simulation of hot pressing head is required by Workbench of ANSYS software. After taking the assessment of the hot pressing head performance in different working conditions with different materials, a structure which matches well with the machine is worked out through the analysis.Finally, by way of the performance test of the stability and precision of temperature and pressure control, the hot pressing machine is working in a good condition. What’s more, the research of the influence of the temperature and pressure to contact resistance is been doing, which prove the consistency of the machine’s performance.
