Final testing procedures are performed to assure the quality of manufactured parts before their shipping to customers. Turret based test handler is a general kind of IC Test Handler for final testing. This paper discusses how to develop a general control system for a test handler of turret style in which every workstation moves up and down separately based on an industrial control computer. The combination of object-oriented programming and the cycling scanning working mode is the key of the whole system. To achieve ideal performance, special control flags are designed as an efficient way for making all the workstations work as setting orders stably. The method to developing the control system in this paper can be also applied to similar systems, which would greatly reduce development cycles. A turret based test handler with this control system has passed the test of a semiconductor factory and operates well in actual production.

One of the main problems arising at the industrial enterprises of Kryvyi Rih region is formal attitude to the questions of safety, especially at production level. Such formal attitude is evinced in forming of the system which just excludes the outgrowth of dangerous situations into hazardous events. To avoid this it is necessary to expose and teach leaders choosing them from top, middle and low-level managers. Such leaders would introduce the development of occupational health safety culture into the general control system of an enterprise requiring the acceptance and implementation of rules by the staff in daily practice.
