Performance Analysis of Reflow Oven Machine through Overall Equipment Effectiveness (OEE) and Six Big Losses

Abstract

The development of the manufacturing industry demands increased efficiency and effectiveness in the production process. One important factor that influences productivity is the performance of productionn machines, including reflow oven machines used in the soldering process of printed circuit board (PCB) components. In recent years, monitoring the performance of production machines has become the main focus in the industry. This research proposes to analyze the performance of reflow oven machines using the Overall Equipment Effectiveness (OEE) and Six Big Losses methods to determine the level of equipment effectiveness and the main factors causing reduced productivity. Data were collected through direct observation of operation, downtime, and the quantity of defect products over several months on three reflow oven (R.O) machines. OEE calculations are based on three main components, which are Availability Rate (AR), Performance Rate (PR), and Quality Rate (QR). Then, the OEE results are analyzed further to identify Six Big Losses that have an effect on machine efficiency. The analysis results show that the average OEE value of three machines is in the category of needing improvement because from observations that have been carried out for several months on three machines, based on observations conducted over several months on three machines, only one month met the company's OEE standard of 85.00%, on month I which is 87.12%. The analysis results indicate that the average OEE value of three machines in three months observation is in the category of needing improvement. Keyword: OEE, Reflow Oven Machine, Six Big Losses
