The invention discloses plug-in-class positive temperature coefficient (PTC) resistor production technology in the field of electronic component manufacturing. The plug-in-class PTC resistor production technology comprises the following steps that in a preparation step of a semi-finished product body, a PTC semi-finished product body is obtained by preparing raw materials; in an electrode printing step, two end surfaces of the axial direction of the PTC semi-finished product body are successively printed with an ohmic electrode and a surface electrode to obtain a PTC resistor body; in a braiding step, pins are connected and inserted along the axial direction of a paper tape, two pins are taken as one group and are evenly arranged along the axial direction of the paper tape; in a welding step, the PTC resistor body is placed between two groups of pins, and the axial direction of the PTC resistor body is parallel to that of the paper tape; the two groups of pins are respectively welded with surface electrodes on two end surfaces placed in the axial direction of the PTC resistor body through soldering technology to obtain a plug-in-class PTC resistor; and the welding temperature of the welding step is 400-460 DEG C. The plug-in-class PTC resistor production technology has the advantages of being capable of obviously improving production efficiency of the plug-in-class PTC resistor and economic benefits of an enterprise.
Description
technical field [0001] The invention relates to a production process of plug-in PTC resistors. Background technique [0002] Plug-in PTC resistors are now more and more widely used in various home appliances and electrical equipment. PTC resistors are produced in large quantities.
