Reflow Soldering of Through-Hole Components Phil Zarrow, ITM, Inc. The rallying cry of manufacturing has been "do it cheaper, faster, better". Consequently there is a constant drive to reduce the cost of the product. After the cost of material, the cost of manufacturing is usually the most significant area contributor to product cost. The SMT manufacturing process is constantly being examined for ways of streamlining assembly. Aside from faster (and hopefully accurate) equipment, elimination of process steps is a practical approach to the enigma. Each process stop carries with it related capital costs for the equipment utilized as well as recurring costs for process material, support labor, equipment spare parts, and, of course, overhead such as floor space, power, and other utilities. In many cases, steps can sometimes be eliminated through incorporation of advanced SMT manufacturing methods. Bear in mind that alteration of the assembly process in such a manner will entail formal process development using designed experiments and statistical studies if the manufacturing process is indeed to be optimized.
