Abstract

PSi Technologies, Inc. is a company that focuses on assembly and test services of power semiconductor and specialized non-power semiconductor packages used for industrial, automotive, and computer peripherals. It is located in Electronics Avenue, FTI Complex, Taguig City. The company has the lowest efficiency in producing the TO-220 ON-GDL products. It has the lowest efficiency of 91.0706%. In addition, it is behind its target efficiency of 95%. Each 1% lost in efficiency is equivalent to 41,075 units per week which is equivalent to Php64,046.94 per week. Furthermore, given the current capacity with low efficiency, the system cannot satisfy the demand for 2008. Breaking down the operations in producing the product reveals the mold station as the bottleneck process. In addition, it has the lowest efficiency recorded and is behind its target efficiency equal to 98%. It's current efficiency in producing TO-220 ON-GDL is 94.94%, behind its target by 3.06%. The mold station is behind its effective capacity by 208,000 units which is equivalent to Php324,324 per week. Root cause analysis was done and cause factors were derived. The cause factors were grouped into man, Machine, Method, or Noise, and Experimental Factors. Since the Noise factors were not within the scope of the study, it is not addressed. Six controllable factors were derived and given solutions. These factors were grouped into three-Factor C1, C2 and C3. Recommendation for the first factor was that the management should make sure that the task of checking the availability and condition of the mold compound inventory is being fulfilled by the material planner. Second, management should not overlook the poor implementation of its rules and regulations. The rules described here are those regarding tardiness and loitering of the employees. Third, standard operating procedures should be strictly reminded and a re-training of workers was suggested in order to avoid mistakes in production. Two experimental factors were identified. Factor A is the mold tool has exceeds its optimum number of shots while Factor B is the poor inventory system For Factor A, Alternative A was presented. For Factor B, Alternatives C and D were given. Alternative A suggests the replacement of mold tool which increased the capacity per week by 86,000 units. Alternative B suggests the use of lot for lot technique in ordering the required molding compound while Alternative C uses Economic Ordering Quantity or EOQ. For an experimental factor, one alternative solution was chosen. Factor rating method was done in order to come up with the selection. Based from the ratings done, Alternative A was the solution for Factor A and Alternative B was the solution for Factor B. It was determined that upon implementation of the solutions to the problem, the TO-220 ON-GDL products would increase its efficiency by mold 3.57% in the mold station, from 94.94% to 98.51%.
