2.2 flow analysis process in the Clean Room
.The study and data storage function of the main production process of a case study Clean Room researcher principles and theories SLP to improve plant layout Starting from the analysis of the flow of the manufacturing process since the station Stock HSA (Head Stack.Until the station LPP (Leak / Particle Purging) by SUB station station and HDE (Hard Disk Enclosure) has the form of a production line 3 forms. Conveyor (Con),Modular Step1 (MDL Step1) and Modular Phase2 (MDL Ph2), the station LPP production line 2 forms Conveyor (Con) and Modular. Step1 (MDL Step1) work in the Clean Room have all 16 work station and divide the work into 2 parts is phase 1 (work station that 1 to 5). And the phase 2 (work station that 6.16) as shown in Figure 1 in parts of the phase 1 the production process since the station Stock HSA until the station HDE and in phase 2 has produced since the station. Stock HSA until the station LPP will see that both phases are working process are mainly the same.See the proportion of production in the figure 1 considering phase 1 can be seen that when the material out of the station Stock HSA with capacity 65% will be forwarded to the station. HSA with capacity 61% so material remaining 4% of 1 phase.HSA phase 2 in the same manner, the material being sent me another phase 3 route is from the station HSA phase 1 station DI Cleaning phase 2 from the station. DI Cleaning phase 1 station SUB Conveyor phase 2 and from the station HDE Conveyor phase 1 station LPP Conveyor phase 2.
