While many defluxing technologies exist, spray-in-air based technologies remain the most popular. Within the spray-in-air defluxing equipment marketplace are batch and inline defluxing systems. The shift of high production lines from the United States to regions abroad has caused batch format defluxing systems to become the dominant defluxing configuration.
Mr. Konrad will discuss the best-practice design criteria of batch and in-line format defluxing systems. This paper reviews various designs and their suitability to specific modern cleaning challenges including lead-free, high-density component population, under component impingement and shadowing.
