[Elecraft] Resistor networks, polarized?

[Bob]

I also believe it is better to remove it and the extract the pins one at a 
time.  A method that I've used many times is to slowly and gently rock the part 
back and forth.  First you will only get very little movement but with metal 
fatigue it increases.  Eventually with care it breaks off cleanly and the pins 
are easy to extract. Two hazards associated with cutting them.  They shatter and 
are an eye hazard but you should be wearing eye protection even clipping wires 
etc.   Second there is more board risk with the cutters.  It is pretty easy to 
nick or cut a land on the top of the PCB with the cutter tips.

Boils down to what you are comfortable with.  The average ham will not have the 
Pro rework station equipment where there is a tip to heat all the leads and 
extract the component intact.   No matter what method you use "care" is the 
operative word.
