When setting out to write this chapter the author is conscious that the classical method of deciding whether ACI is cost-effective is simply to establish the rate of ACI assembly and decide whether the return on investment is justified compared with the use of assembly operators. This simplistic approach to the subject takes absolutely no account of all the other effects that ACI will introduce. The ACI influence is such that if it is introduced to a factory or assembly operation correctly, practically every other operation in that factory relating to assembly operation should change or adjust in order to make the best use of ACI. This includes everything from component procurement and goods-inwards inspection to decisions on final inspection and test, from the management stand-point, and from a technical stand-point. There will be an immediate improvement in both the reliability of finished boards post-ACI due to correct assembly, and an improvement in soldering and cleaning due to correct insertion, cropping and bending standards.
