RAD 750, SN 031

1
RAD 750, SN 031

• Inspection findings
• A solid continues bead of material fillet was
  evident on both sides (2nd step) of the EEPROMs
  U6, U8, U11.
• Material fillet was observed at the front of U6
  and at the end of U11 (2nd step). Unable to view
  either ends of the other ICs with the mini
  mirror due to not enough clearance in between the
  ICs bodys (could not photo due to location).
• No cracks were observed in the staking material
  around the posts of U5 U16 Ref NC781.
• Missing J7 cover plate and hardware.
• Flux residue under capacitor and on top of solder
  joint (Location near U11)
• Different type of hardware (nuts) used to install
  front panel. View RAD 750 S/N 031 012.
• J1 Connector damage at initial receiving
  inspection ref NC 748. BAE repaired with epoxy.

RAD 750 SN 31, U6

• U6 (pin 1) able to view a solid continues bead of
  material fillet on both sides of the EEPROM at
  the 2nd step.
• U6 (pin 32) able to view material by using a mini
  mirror.

RAD 750 SN 31, U8

• U8 (pin 1) able to view a solid continues bead of
  material fillet on both sides of the EEPROM at
  the 2nd step.
• U8 (pin 32) able to view material by using a mini
  mirror.

RAD 750 SN 31, U11

• U11 (pin 1) able to view a solid continues bead
  of material fillet on both sides of the EEPROM at
  the 2nd step.
• U11 (pin 32) able to view material by using a
  mini mirror.

RAD 750 SN 31, U16Ref NC781No cracks observed
in the staking material around the U16 posts
7
RAD 750 SN 31, J7Ref NC803

• SLAC received the RAD 750 without a cover plate
  and hardware for J7.

RAD 750 SN 31,Ref NC 803 Flux residue
capacitor near U11

• Flux residue exhibited under the conformal coat.
• SLAC removed contamination and reapplied
  conformal coat. With customers approval.

RAD 750 SN 31 Discrepant hardware

• Two different types of nuts are installed to
  secure the front panel. 3plcs
• SN 12
• SN 31

RAD 750 SN 31, J1 ConnRef NC 748

• Shield damage at the edge of J1 connector was
  observed and documented on NC 748 when CCA was
  received at SLAC in Nov 2005.
• CCA was returned back to BAE for evaluation and
  repair EEPROMs. BAE applied epoxy around the
  damaged area of the connector shield. To prevent
  any additional lifting of the connector shield.

RAD 750 SN 31

• Inspection completed and RAD 750 installed back
  into original crate. S/N GLAT 2526, Pending vibe
  testing.
