摘要: Light-weight items or components may be picked-up and moved from space restricted areas. The method of lifting and placing such items involves the use of a hand-held tool, comprising a hollow tube containing a suction creating device, which suction creating device may be engaged by pressing an actuator member located in a hole in the hollow tube. A tip is attached to an open end of the hollow tube, so that air is expelled from and drawn into the suction creating device in the hollow tube through the tip. A gripping member is removably attached to the tip. The gripping member comprises a suction cup, an extension tube, and a fitting by which the gripping member is attached to the tip. A variety of gripping members, with suction cups of varying sizes and extension tubes of differing angles, may be used with the pick-up device. After expelling air from the suction creating device by use of the actuator member, the pick-up tool is lowered onto the item to be picked up, so that the suction cup comes into contact with that item. The actuator member is then disengaged to allow air to be drawn into the suction creating device, causing the item to be held against the suction cup. In this way, the item may be moved to another location, and released by depressing the actuator member.

摘要: A hand held tool for grasping and moving light weight objects includes a battery powered vacuum. Upon pressing an actuator, an electrical circuit is completed, activating the vacuum pump. The vacuum pump draws air from a valving system, causing air to be drawn through a nozzle. A variety of gripping devices may be attached to the nozzle, so that air is also drawn through the attached gripping device when the vacuum pump is activated. As a result, the gripping device may be placed in proximity to a light weight object, so that activation of the vacuum pump results in that object being held against the gripping device, for ease of movement, until the vacuum pump is deactivated.

摘要: Leaded and leadless surface mounted devices are removed from or attached to a printed circuit board at various locations, without interfering with or adversely affecting other chips on the printed circuit board. The method of removal involves placing a tool on the substrate, comprising a rigid plate containing a hole, and a hollow tube extending beneath the hole from the rigid plate to the substrate. In this way a surface mounted device to be removed may be surrounded completely by the hollow tube, without encompassing adjacent chips. When heat is directed through the hole in the rigid plate and through the hollow tube to the surface mounted device, the soldered connections attaching the surface mounted device to the board may be melted. A disconnecting means is utilized to remove the surface mounted device from the substrate at the moment the soldered connections are melted or, in the case of non-eutectic solder, changed to a plastic phase. The same tool may be used to facilitate the attachment of a surface mounted device to a printed circuit board, by applying hot gas to the component to be attached, through the hollow tube surrounding that component, as solder is applied to form a plurality of soldered connections.
摘要翻译: 带引线和无引线表面安装器件在各种位置从印刷电路板上移除或附着到印刷电路板上,而不会干扰或不利地影响印刷电路板上的其它芯片。 去除方法包括将工具放置在基板上,包括含有孔的刚性板和在孔下方从刚性板延伸到基板的中空管。 以这种方式,待移除的表面安装装置可以被中空管完全包围,而不包括相邻的芯片。 当热被引导通过刚性板中的孔并且通过中空管到达表面安装装置时,将表面安装的装置连接到基板上的焊接连接可能被熔化。 在焊接连接熔化的时刻,或者在非共晶焊料的情况下,改变为塑性相,利用断开装置将表面安装的装置从衬底上移除。 可以使用相同的工具来通过将围绕该部件的中空管施加热气体到待连接的部件上,以便将表面安装的装置附着到印刷电路板上,因为焊料被施加以形成多个焊接 连接。
