desoldering problem

Hi and thanks for reading this post.

I have a bad capacitor on a motherboard and in order to change it i purchased a reel of desoldering wick from ebay, just a generic brand from china.

After applying onto the joint and plenty of heat the wick would not draw up any of the solder, then i used a large blob of solder paste which helps the solder to melt more easily, but nothing.

I was advised that "Goot" is a good brand of desoldering wick so back i went on ebay, when the stuff arrived it was useless.

Has anyone actually purchased desoldering wick which works first time without any of all this hassle i am experiencing, where is a reliable source which will deliver what they advertise and not rip me off.

Many thanks in advance. John.

I don't think that you can easily clear a small (wire sized) hole on a printed Circuit Board; the Surface Tension, of the liquid Solder, is too great but you should be able to see the hole clearly.

You may succeed after repeated attempts.

that's why you buy small drill bits from maplins to clear the holes, you can use them with your fingers to clear holes that still have solder in them, but a cocktail stick wood one should do the same job if solder is hot when you probe the hole
