wuming79 said:Hi, sorry, I meant to type 20W instead of 200W. So how do I desolder it??
Thunderchild said:you probably have a dirty iron tip or there is a dip in the centre where u always "make contact"
1 clean the tip with a file
2 do put solder on the tip before desoldering as this will help make a better contact that the plain metal.
remember that a lot of inriustrial soldered stuff is done with extra hard solder that is more difficult to melt
wuming79 said:ok.....I got a soldering iron with 51W and I still can't melt it!!!!!! Is there such a solder wire that becomes permanently hardern on MB????
