背景技术Background technique

随着人们对健康的追求，加热不燃烧型电子烟越来越受欢迎，管状加热器作为加热不燃烧电子烟载体，是加热不燃烧型电子烟的核心部件。现有的不燃烧型电子烟的焊盘一般使用锡焊，最高使用温度一般在200℃以下，使用场景十分受限，电连接可靠性也较差；并且，仅使用1个连接孔连接将内部线路与外部焊盘连接，这种焊盘结构在反复加热时容易造成虚弱连接(即虚接或虚焊)，电连接可靠性较差；另外，当前的焊盘结构一般通过不同引线颜色管理实现对焊盘引脚功能的管理，操作人员容易将引线颜色对应的焊盘引脚功能搞错，以此容易引发焊接错误的问题，会对器件使用造成不便。With people's pursuit of health, heat-not-burn electronic cigarettes are becoming more and more popular. As the carrier of heat-not-burn electronic cigarettes, tubular heaters are the core components of heat-not-burn electronic cigarettes. The pads of existing non-combustible electronic cigarettes are generally soldered, and the maximum operating temperature is generally below 200°C. The application scenarios are very limited, and the reliability of the electrical connection is also poor; moreover, only one connection hole is used to connect the internal The line is connected to the external pad. This pad structure is likely to cause weak connection (that is, virtual connection or virtual soldering) when heated repeatedly, and the reliability of the electrical connection is poor. In addition, the current pad structure is generally realized through different lead color management. For the management of pad pin functions, operators can easily mistake the pad pin functions corresponding to the color of the lead wires, which can easily lead to soldering errors and cause inconvenience to the use of devices.
