SOLDER BALLS are particles of un-coalesced solder often found around leads, and in the spaces between the leads and the solder mask. They are generally found in clusters, and will range in size from 1-5 mils in diameter.

 
 

SOLDER BEADS are a type of solder ball found alongside capacitors, resistors, or other low standoff lead-less components. They generally range in size from 5 to 30 mils in diameter.
