Solar 8000/View Disassembly Guidelines
General Follow the guidelines described when disassembling Solar 8000
processing unit or SolarView remote display controller. You will require a
standard set of hand tools.
PCB Assemblies
Observe the following guidelines when working on all PCB assemblies:
• Take against electrostatic discharge damage.
• Handle all PCB assemblies by their edges.
• Generally, use 60/40 low melting point solder. Use high melting point
silver solder when working on the surface mounted components.
• Use a heatsink when soldering any photo-transistors, photodiodes, or
optical isolators.
• Repair breaks in PCB tracks by bridging with wire from pad to pad.
Do not lay solder across the breaks. (The heat from the soldering iron
may cause the track to detach from the PCB.)
• After soldering, clean excess flux from the PCB assembly.
• If you replace the main processor, remove the serial EEPROM U9
and insert it into the replacement main processor PCB. The serial
EEPROM must stay with the unit.
Hardware • Before disassembly, note the positions of any wires or looms (cables),
marking them if necessary to ensure that they are replaced correctly.
• Gray ribbon cables have retainer clips holding them in the connector.
• Save and set aside all hardware for re-assembly.
