2. how to conduct research.2.1 scope of research.Hard disk drive manufacturing process can be divided into two major sections: Room Clean and Normal Area of research this research only that portion of the Clean Room only.2.2 analysis of the flow of the production process in a Clean Room.From the study and observation of the main routes in the Clean Room of the factory case study researchers have taken the principles and theory of adjustment applied to SLP factory. Starting from an analysis of the flow of the production process from the HSA Stock station (Head Stack Assembly) until it reached the station, the LPP (Leak/Particle Purging) by SUB station and station there HDE (Hard Disk Enclosure) model of production line Conveyor is the format 3 (Con), Modular Step1 (MDL Step1) and Modular Phase2 (MDL Ph2) station, there are production lines, LPP.Format 2 is the Conveyor (Con) and Modular Step1 (MDL Step1) to work in a Clean Room with all 16 channels, and split the work into 2 parts: the phase 1 (the channel 1 to 5) and phase 2 (6 to 16 work stations), as shown in Figure 1 in section of phase 1 with the production flow from HSA Stock station to station and HDE in phase.There are 2 stages productions from HSA Stock station until LPP station can be seen that both fetmi most of the work process are the same, but not the same capacity, and is therefore a problem of capacity imbalance. Seen from the proportion of capacity in Figure 1 when considering that phase 1 will see that when material from Stock with HSA station capacity 65% will be forwarded to HSA station with 61% of capacity, so that the other 4% of phase 1 is sent across to access HSA station phase 2 in the same manner. There is material that is sent across the phase 3 another way is from phase 1 to HSA DI station station Cleaning phase 1 phase 2 from SUB station DI Conveyor Cleaning phase 2 phase 1 and HDE station Conveyor to Conveyor 2 LPP station phase.
