Abstract: A removal tool for removing a component bonded to a printed wiring board. A housing and securing mechanism are provided for securing the printed wiring board to the housing. An adapter holds the component that is to be removed. A variable jaw assembly applies a closing force to the adapter to hold the component. A spanner assembly comprises a variable position slider block for holding the jaw assembly in a vertical orientation, and locking devices for securing it to the housing. A second securing mechanism is provided for locking the slider block to secure the variable jaw assembly. A torque handle assembly is coupled to the jaw assembly that is rotatable to apply torque to the component to break the bond between the component and the printed wiring board. The securing mechanism comprises a support block, an end stop, a swivel block disposed opposite the end stop, and a locking device for supporting and holding the printed wiring board in the housing. The slider block is captivated by a slot in the spanner assembly that is used to lock the jaw assembly in a vertical direction. The slot provides a limit to rotation when force is applied to the handles during removal of the component. The torque handle assembly comprises two L-shaped blocks for grasping a shaft of the variable jaw assembly and anchoring two dowel pins. The variable jaw assembly comprises a housing, two pivotable jaws secured to the housing that are each rotatable around a pivot shaft, a partially threaded shaft having a left-hand threaded portion and a right-hand threaded portion disposed through the respective jaws, and a disk attached to a center portion of the partially threaded shaft having that permits turning thereof in response to rotation of the disk. The removal tool permits safe removal of components from printed wiring boards without damage to the surface thereof or to the component. The removal tool provides the capability of grasping and removing components of various sizes and shapes that are confined in the midst of other adjacent components on the surface of the printed wiring board.

Abstract: A motorized strip solder feeding device including a spool of strip solder which may be mounted on a soldering iron for selectively feeding strip solder to the heated tip. When the strip solder on the spool is depleted, the spool may be mechanically connected to the motor to automatically renew the solder supply. The mechanical connection between the motor and spool is formed by a short length of solder.

Abstract: Pickup device (24) is for mounting on the mounting plate of a positioning robot. The pickup device has a frame (30) which carries movable carriages (36, 38). Cam ring (50) controls the position of the carriages. Downwardly depending arms (60, 62) carry pairs of levers thereon. The levers have facing sloped cam surfaces (84, 86) which are spread by downward thrust of closing pin 88. When the closing pin drops too far, it indicates lack of grasp and this is signaled by contacts (114, 116).

Abstract: A method is disclosed for the temporary retention of insulated electrical leads by a printed circuit board preparatory to permanent electrical and mechanical attachment. Also disclosed is apparatus for forming the leads for said retention. The lead has a metallic wire therethrough with a residuum of elasticity. The printed circuit board consists of an insulative sheet with a plurality of selectively interconnected metallic electrical terminals each having a hole therethrough smaller in diameter than the outside diameter of the electrical lead, but larger in diameter than the wire by a factor of appreciably greater than 2. The method according to the invention comprises stripping the insulation from an end of the lead to provide a predetermined length of wire projecting from the abutment of the insulation formed by the stripping. The wire is then folded to form a narrow J-hook, the folded width of which is appreciably greater than the diameter of the hole. The point of the fold is selected such that the distance between the tip of the wire and the abutment of the insulation is substantially equal to the thickness of the board. The tip of the wire is offset to form a spur. When the retentive configuration is inserted into the hole, the J-hook is constricted to provide entry into the hole and thereafter, because of its residuum or elasticity, expands. The abutment of the insulation limits the distance of entry of the wire into the hole, and the spur, together with the expansion of the J-hook, inhibits withdrawal of the lead from the hole.

Abstract translation: 公开了一种用于通过准备永久电气和机械附接的印刷电路板临时保持绝缘电引线的方法。 还公开了用于形成用于所述保持的引线的装置。 引线具有穿过其中的金属线，具有弹性残留。 印刷电路板由具有多个选择性互连的金属电端子的绝缘片组成，每个绝缘片具有直径小于电引线的外径的孔，但直径大于导线的直径大于2倍 根据本发明的方法包括从引线的端部剥离绝缘体，以提供从剥离形成的绝缘体的邻接部突出的预定长度的电线。 然后将线折叠以形成窄的J形钩，其折叠宽度明显大于孔的直径。 选择褶皱的点使得线的尖端和绝缘体的邻接之间的距离基本上等于电路板的厚度。 电线的尖端偏移以形成支线。 当保持构造插入孔中时，J形钩被收缩以提供入孔，此后由于其残留或弹性而膨胀。 绝缘体的邻接限制了电线进入孔的距离，并且尖齿与J形钩的膨胀一起阻止了铅从孔中的撤出。

Abstract: U-shaped heater (42) carries busses (22, 24) which are electrically connected to supply heating power. Heated tip (58) is secured to the front of the heater and is as wide as is necessary to at the same time reach all of the leads to be soldered. The heater and busses rock on a pivot provided by pin (18) close to the heated tip so that rocking causes little lateral dfisplacement. Rocking in the single plane is limited by the busses engaging on the back of body (12) and the thermocouple connector body engaging on the front of the body, both in sliding engagement. Spring (62) holds the movable parts on the pivot pin and centers the heater.
