There is one hole on one board that I work on that always give me trouble. These are through-hole solders with a tab instead of a post. All the other ones I do are fine but this one hole always ends up trashed.
Here are some pics of the board and the problem hole. The purple arrow points to the other hole on the board that always turns out fine.
I use the same method on both: lots of flux. Chisel tip heated to 350C. Solder wick all the solder that I can from both sides, then pull the tabs out. Every time the one hole is fine while the other is trashed. I have to resort to picking out the old solder with a pick if I can't blow it out with hot air.
What am I doing wrong?
