The following temperatures worked well for me:
150ºC hot air for softening adhesives.
290ºC for removing old solder.
Make sure to add liquid flux before removing all traces of old solder, & clean all surfaces.
Apply new flux to both sides of Kapton cables as well as the board. Set your iron temperature acording to the recommended setting for your ROHS electronics solder.
*DO NOT USE NON ROHS or lead bearing solder*
*DO NOT USE plumbing or acid core solder as this will destroy your electronics*
For those using rework stations, what temperatures are recommended for the iron & hot air blower?
