Filed:

Jan 10, 1994

Appl. No.:

8/179287

Inventors:

Joseph M. Jacobs - Redondo Beach CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

H05K 1300

US Classification:

29762

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.

International Classification:

B23K 304

US Classification:

219233

Abstract:

Heater bar assembly for a reflow solder machine comprises first and second fingers (50, 52) carrying U-shaped heater bar (54) which is pivotable on main member 22. A spring urges the heater bar assembly to the centered position. First and second thermocouples (82, 84) are secured to the heater bar (54) and are connected through a transfer switch (104) by which their electrical connections can be alternated. One controls the power supply and the other cuts off the power supply if temperature exceeds the selected temperature.

International Classification:

B65H 3902
B26D 706

US Classification:

270 58

Abstract:

Apparatus for blanking and collating a plurality of individual pyrolyzable sheets having electrical circuit patterns formed thereon from an integral pyrolyzable sheet having the electrical circuit patterns for the individual sheets printed thereon, where the individual pyrolyzable sheets comprise layers of a hybrid module. The apparatus includes a die having substantially identically sized openings for supporting the integral printed pyrolyzable sheet, a punch assembly engageable with the die for blanking the integral printed pyrolyzable sheet into a plurality of substantially identically sized sheets having electrical circuit patterns formed thereon, and a collation structure located beneath the means for receiving the blanked sheets from the die and for stacking the blanked sheets.

International Classification:

B25B 718

US Classification:

2941191

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).

International Classification:

US Classification:

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.
