The invention discloses a connecting method and device for an external wire of a central processing unit (CPU) module. The connecting method comprises a first step of adding rosin on a preset welding spot of the CPU module, a second step of placing the wire on the preset welding spot and enabling one end of the wire to be placed on the preset welding spot, a third step of adding solder balls on the preset welding spot and a fourth step of enabling one end of the wire and the solder balls to be welded to the preset welding spot. The connecting device for the external wire of the CPU module comprises an annular rotating wire welding mechanism (1) for adding the rosin, placing the wire, adding the solder balls and welding the wire on the preset welding spot of the CPU module. The connecting method and the connecting device have the advantages that the rosin is added to the preset welding spot of the CPU module and protects a welded position and isolates air in welding, oxidation of the welded position is avoided, service lives of finished products are improved; simultaneously, the connecting device is small in size and convenient to install, a processing station is arranged on the periphery of a round turnplate, and processing efficiency is improved.
Description
technical field [0001] The invention relates to the field of mobile communication, and more specifically relates to a connection method and a connection device for an external wire of a CPU module. Background technique [0002] With the rapid development of information technology and economy around the world, economic and information exchanges between people are becoming more and more frequent. Cards and contact CPU cards (smart cards) that are being used in many fields now. At present, smart cards still play an irreplaceable role in people's lives. Whether it is a contact smart card or a contactless smart card, it has its own advantages and disadvantages. The wear and tear between the contact smart card and the card machine greatly shortens its service life. . The application of non-contact cards is limited in the occasions where radio frequency interference is severe; secondly, due to the energy transfer through coupling, the power consumption is required to be very low;...
