CD-ROM Replication

• Plastic pellets are vacuum fed from the PC System (Poly- Carbonate) into the molder
  
  
• Pellets are then heated and transported into the barrel of the molder
  
  
• Liquid form pellets are then injected into the mold and pressed to the "master"
  
  
• A molded un-metalized disc is then put into the input buffer
  
  
• The input buffer indexes until a disc is in the pick position, blowing cool the disc
  
  
• The central robot picks the disc from the input buffer and positions it over the load lock
  
  
• The disc is placed into the load lock which is then pumped to vacuum
  
  
• The disc is then indexed to the sputtering chamber where it receives its metal coating
• The disc is then transported back to load lock, which is then vented
  
  
• The central robot then picks the disc out of load lock, and indexes the disc over the coat bowl
• The disc is put on the spinner chuck, which then begins to rotate
  
  
• Lacquer is then dispensed onto the inner diameter (ID) of the disc
  
  
• The disc is rotated at high speed to spread lacquer across the surface
  
  
• After lacquer is spread, the central robot removes the disc and deposits it to the cure side
  
  
• The cure slide passes the disc under a UV light, curing the lacquer onto the disc
  
  
• The central robot picks the disc and deposits it on the inspection station scanner chuck
  
  
• The scanner inspects the disc for any flaws
  
  
• The central robot then deposits the disc onto an accept or reject spindle
