A SSIGNMENT 5: P RODUCT D ISASSEMBLY L ABORATORY R EPORT Presented By: Louie Pronstroller Team Member: Michael Tabuzo Fall 2009 Class: IE 203 Professor Paul G. Ranky Due Date: December 4, 2009

D ISASSEMBLY P ROCESS S TEPS 1. A CD-ROM DRIVE WAS CHOSEN BY THE TEAM AS THE ELECTRONIC DEVICE TO BE DISASSEMBLED. 2. T HE N ECESSARY TOOLS WERE OBTAINED (3 SMALL P HILLIPS HEAD SCREWDRIVERS, 1 MULTI - TOOL W / FLATHEAD SCREWDRIVER & A SMALL PAIR OF LONG NOSED PLIERS ) FOR TAKING APART CD-R OM DRIVE SMALL SILVER METAL SCREWS WERE REMOVED FROM METAL BOTTOM PLATE. 4. O UTER CASING WAS SEPARATED FROM DEVICE. 5. T OP CASING OF DEVICE WAS PRIED OFF USING A FLAT HEAD SCREWDRIVER FROM MULTI - TOOL. 6. P LASTIC FACEPLATE WAS PRIED OFF WITH THE SAME METHOD AS PREVIOUS STEP.

D ISASSEMBLY P ROCESS S TEPS 7. 4 S MALLER BLACK METAL SCREWS WERE REMOVED FROM A RECTANGULAR DULL SILVER METAL PLATE (CD READER ) CONTAINING THE LASER COMPONENTS. 8. T HE CD READER PLATE WAS SEPARATED FROM THE DEVICE. 9. T HE CD READER PLATE CONTAINED ONE SMALL SILVER SCREW THAT WOULD NOT LOOSEN. S CREW WAS PRIED OFF USING A LARGER FLAT HEAD SCREWDRIVER VERY SMALL METAL SCREWS WERE REMOVED FROM COMPONENT FOR FURTHER DISASSEMBLY. 11. T HE CIRCUIT BOARD WAS SEPARATED FROM CD-D RIVE WITH FLAT HEAD SCREWDRIVER. 12. T HE CIRCUIT BOARD WAS DISASSEMBLED INTO 2 SECTIONS. 13. T HE SMALLER C IRCUIT BOARD SECTION CONTAINS A SMALL MOTOR. M OTOR WAS REMOVED BY FLIPPING OVER THE SECTION AND DISCONNECTING A PLUG & WIRE FROM A 2- PRONGED CONNECTOR.

Work!!

D ISASSEMBLY P ROCESS S TEPS 14.T HE VOLUME DIAL & HEADPHONE JACK ON THE SMALLER SECTION WERE ATTACHED WITH A GLUE AND RIVET METHOD SO THESE WERE NOT REMOVED. 15.T HE INFORMATION TAPE CONNECTING THE CIRCUIT BOARD SECTIONS TOGETHER WAS DETACHED WITH A SLIGHT TUG. 16.T HE PLASTIC CASE OF THE DEVICE WAS FURTHER DISASSEMBLED INTO 2 SMALLER SECTIONS. 17.O NE SECTION CONTAINED A SMALL BLACK REMOVABLE PLASTIC CD TRAY HOLDER THAT WAS EASILY LIFTED OUT BY PRYING THE SIDES WITH THE FLATHEAD SCREWDRIVER. 18.T HE FRONT OF THIS PLASTIC TRAY CONTAINED A THIN BLACK RUBBER BAND AND GEAR PULLEY MECHANISM. T HE 2 PLASTIC GEARS WERE PERMANENTLY ATTACHED TO THE TRAY BUT THE BAND WAS SEPARATED FROM THE PULLEY. 19.I NVENTORY OF PARTS WAS PERFORMED WHILE TOXICITY / HEALTH RISK ISSUES WERE ASSESSED & RESEARCHED VIA INTERNET. 20.D ISASSEMBLED COMPONENTS AND SURROUNDING WORK AREA WAS CLEANED.

Component List 1.1 metal bottom plate 2. 1 metal top plate (Held in by 4 small silver screws) 3. 1 plastic CD tray 4. 1 plastic CD tray frame 5. 1 plastic front face frame 6. 1 black plastic tray guide 7. 1 white plastic gear 8. 1 black rubber band 9. 1 metal rectangular plate (for holding top of disc in place) circuit board w/ microchips (includes small detachable motor with female connector) metal screw to hold CD reader (4 small metal screws with 4 rubber stoppers) small silver metal rods to hold CD reader/writer head laser eye (held by 8 small black metal screws) black cylindrical rotating CD holder small copper brackets (held in by 2 small silver screws) larger white plastic laser eye component small motor attached to a positioning sensor and brass calibrating rod

A DDITIONAL I NFORMATION M Y TASKS : LIST PARTS & ACCOUNT FOR COMPONENTS DISASSEMBLED. PROVIDE DISASSEMBLY ASSISTANCE TO MIKE. H AND - SKETCH DISASSEMBLY. WORK AREA CLEAN - UP. DBOM CREATION IN V ISIO. M ICHAEL ’ S TASKS : TOOL COLLECTION. MOST OF THE D EVICE DISASSEMBLY. S HARED TASKS : COMPONENT SAFETY RESEARCH. WASTE MANAGEMENT. D ISASSEMBLY ANALYSIS. P ROFESSOR R ANKY ’ S CONTRIBUTION : PHOTOGRAPHY SKILLS. S UPPLEMENTARY COMPONENT ANALYSIS.

D ISASSEMBLY B ILL OF M ATERIALS

 S HARP EDGES ON METAL BOTTOM PLATE & CIRCUIT BOARD COULD CAUSE MINOR CUTS IF PROPER CARE IS NOT TAKEN.  O THER THAN SHARP CORNERS, DEVICE IS NOT HAZARDOUS TO TOUCH.  S EVERAL INTERNET SEARCHES PROVED INCONCLUSIVE REGARDING HARMFUL CHEMICALS IN PLASTIC PARTS, CIRCUITS, SOLDER, WIRES, METALS, OR GEAR LUBRICANTS.  T OXIC ISSUES ARE CURRENTLY NON - EXISTENT WITH THIS DEVICE DUE TO POOR WEB DOCUMENTATION OF INDIVIDUAL COMPONENTS ’ CHEMICAL COMPOSITION. D ISASSEMBLY R ISK A SSESSMENT !

G REEN A SPECTS  P LASTICS COULD BE RECYCLED IF DEVICE WAS DISASSEMBLED TO COMPONENT LEVEL.  M ETAL SCREWS & METAL PARTS COULD BE RETURNED TO COMPANY FOR RECYCLING.
