Notes: 1) These assemblies are ESD sensitive, ESD precautions should 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) Reference designators marked with an asterik (*) cannot be substituted. All other components can be substituted
with equivalent manufacturers components.
5) Make one EEPROM connector wire assembly for each assembly produced, from J15 mate, 4 − 22 AWG wires and
crimp terminals. Wire colors for pin numbers are listed below. Strip and tin flying leads 0.25 inches from end of wire.
Red − pin #4 (signal VOUT)
Brown − pin #3 (signal SDA)
White − pin #2 (signal SCL)
Black − pin #1 (GND)
