Notes: 1. These assemblies are ESD sensitive, ESD precautions shall be observed.

2. These assemblies must be clean and free from flux and all contaminants. Use of no clean flux is not acceptable.

3. These assemblies must comply with workmanship standards IPC-A-610 Class 2.

4. Ref designators marked with an asterisk ('**') cannot be substituted.

All other components can be substituted with equivalent MFG's components.

5. Make one SMBus connector wire assembly for each assembly produced, from J4 mate, 4–24 Awg wires and Crimp

terminals. Wire colors for Pin numbers are listed below. The wire assembly shall have a J4 mate on each end.

Red - Pin # 4 (Signal USB_5V)

Brown - Pin # 3 (Signal SDA)

White - Pin # 2 (Signal SCL)

Black - Pin # 1 (GND)
