[0003] Because the ultrathin circuit board or FPC cannot be directly operated on the SMT equipment when mounting, it is necessary to make a supporting plate first, and then attach the FPC or ultrathin PCB on the supporting plate, so as to facilitate the mounting and processing of components on the SMT equipment. Most of the existing FPC trays are made of hard steel plate or other hard plate with a layer of micro-adhesive silica gel material, and then the FPC is attached to the silica gel material, so that the hard plate material becomes the hard base tray of the FPC. In the improved technology on July 18, 2016, the applicant Suzhou Mark Liheng Intelligent Technology Co., Ltd. designed a kind of SMT flexible circuit board carrier, which is formed by the principle of magnet adsorption. However, due to the difficulty of extracting the PCB from the carrier and the bottom plate, this invention is applied. UTILITY MODEL CONTENT
