4.6 Common Solder Joint Issues

You can see from the image below some common solder joints that you can make whether
you are expert or a beginner in soldering. Let us discuss some common soldering issues
and see how we can avoid and fix them.

4.6.1 The Ideal Solder Joint

A good solder joint is smooth and shiny and has cone-shape, not a ball or a clump as shown
from the following  image  and  the diagram.  The concave surface’s  wetting  point should  be
between  the  range  40-70  degrees  which  means  that  the  solder  has  not  been  hot  and
exhausted the flux and the leg is in the center of the joint.
