Sorry for all these questions...I' m just ' detail' type of person. Thanks in advance for any info on this.
Use a solder sucker or solder wick to remove all the old solder.
Proper soldering technique is to heat both components equally to a point where they will melt the solder applied to them. You are looking for a nice shiny finish when done.
Do NOT "drip" solder onto them.
Yes, resin and rosin are the same, do NOT use acid core solder ( meant for plumbing purposes )
The joints require quite a bit of heat, a soldering GUN is better that a soldering PENCIL here.
