So I have built some simple circuits involving the 16f628a in DIP packaging, and one thing is that my solder joints are always nasty. There's some messy substance of some kind (I guess the rosin core?) that gets all over the place and my soldering just doesn't look nice and clean like other joints I have seen.
Could somebody clue me in on why my soldering is so bad and ugly? It gets the job done and the circuits work, but I'd like to learn how to make nice looking joints before I get into the habit of just making crappy ones.
What I do is this:
0. clean copper board using iron wool
1. use press n peel and iron to put pattern onto copper board
2. etch using ferric chloride
3. drill holes
4. insert components
5. solder using a thin solder with rosin core
I don't do any cleaning of some kind. Am I supposed to?
Thank you for any responses.
