he potential for innovation in elec- tronics makes it one of the most dynamic industries today. Selec -
tive soldering has seen a dramatic increase for years, more so than any other soldering process in electronics manufacturing. The consistent trend towards the
miniaturization of assemblies means that more and more products are evolv- ing from the classic through-hole layout to reflowable SMT assemblies. This leaves only a few through-hole compo- nents that need to be soldered after reflow. These components may not be available in SMD format or might be significantly more expensive that their corresponding wired compo- nent. These are typically plug connec- tors, electrolytic capacitors or coils, and often, are temperature-sensitive components or electric mobility parts. Due to high quality require-
ments, many sectors of electronics manufacturing today no longer accept the manual soldering of these compo- nents. There are too many uncontrol- lable variables that impede a repro- ducible process and the potential for human error is too great. Also, the

costs of manual soldering are not insignificant. There are also “hidden” costs, such as training for employees and costs for consumables.
Plug-and-Produce Soldering A high degree of automation in
production typically means large investments in machinery. Especially for small or mid-sized production vol- umes, the investment in an automat- ed selective soldering process appears unprofitable. However, this perspec- tive changes if automation is not excessive, but adequate. The result is the perfect inter-
play of man and machine. The priori- ty is on keeping it simple. The opera- tor must be able to understand the processes and know how to operate the system at a glance, what the machine is doing and why. With these factors in mind,
SEHO recently introduced its StartSelective selective soldering sys- tem. StartSelective is a “plug-and- produce” selective soldering system for those just entering the automated soldering field, or for anyone looking for a short-term capacity expansion. It is fully equipped to begin produc- tion immediately. “In particular with regard to
human-machine interaction, we wanted the StartSelective to be really
