I have never done a relay board, however I have repaired many circuit boards in electronic equipment. Use a pencil type eraser to clean the area to be soldered, then flush with isopropyl alcohol. Cleanliness is a must for good soldering.
If after cleaning, the solder does not "flow" well, try some flux. Just be sure to wash again after completed. Tom |
