    • A latch connected to a surface mount component for subsequent connection to a printed circuit board is provided as well as a method for mounting a surface mount component to a printed circuit board having a zero mounting force. The surface mount component has a soldering tail extending therefrom and at least one latch or latch contact insertable through an aperture in the printed circuit board, without force, such that the soldering tails extending from the surface mount component rest on corresponding soldering pads of the printed circuit board. As a result, surface mount components are mountable to a printed circuit board using standard, available equipment, such as a vacuum head placed component which allow for placement of the component via gravity, and the components are subsequently soldered to the printed circuit board. The assembly also includes a board latch pin and a weighted cap.
    • 提供连接到表面安装部件以用于随后连接到印刷电路板的闩锁以及用于将表面安装部件安装到具有零安装力的印刷电路板的方法。 表面安装部件具有从其延伸的焊接尾部,并且至少一个闩锁或闩锁接触件可通过印刷电路板中的孔插入,而不受力,使得从表面安装部件延伸的焊接尾部搁置在印刷的相应焊盘上 电路板。 因此,表面安装部件可使用标准的可用设备安装到印刷电路板,例如真空头放置部件,其允许通过重力放置部件,并且部件随后被焊接到印刷电路板。 组件还包括板闩销和加重盖。
