you don't have a hot enough iron and fast enough fingers, floyd -=B-)

i do this kind of work all the time and have no problems... have even
replaced a 30pin SIMM socket on a 4 layer motherboard >... the
key is patience... you cannot rush the job and you surely don't want to
hold the iron on the work for so long... >

there are, however, some things i won't touch without specialized
equipment... 72pin SIMM sockets, surface mount chips, etc... they do
require heating of all sections at once and removal of the chip/socket
while hot... then its an easy matter to clean out the holes... OB-)
