Hi,
I'm not sure if this is a problem or not. When I desolder resistors
from a PCB, the desoldering wick sucks up enough solder to remove the
resistors, but leaves a thin layer of solder on the copper pads that is
_extremely_ difficult to remove. Is this a normal desoldering
experience? Do I have to remove all of the solder before inserting a
new component, and if the answer is 'yes' do you have any
suggestions on how to do this?
The materials I'm using are:
Desoldering braid dipped in liquid rosin flux
25-watt Weller soldering iron
97/03 tin/silver solder
Thank you very much.
P.S. Also, I would like to thank the people that responded to my
voltage polarity question a couple of weeks ago. You guys really
helped a lot.
