Abstract :

Direct Memory Access (DMA) is a device that performs the function of transferring data between memory and peripheral devices without the intervention of the main processor device (CPU). However, DMA's manufacturing environment is based on trial-and-error testing, and DMA equipment manufacturing conditions depend on craftsmanship and experience, which does not guarantee product quality, leading to up to 99% defective products, increasing production costs and reducing customer satisfaction. This study proposes the Taguchi method to optimize the Mold process to minimize the number of experiments according to the orthogonal grid L18 with factors including nozzle size (mm), Mold temperature (), Mold plastic pushing pressure (Mpa), Binder chemical concentration (%), Mold material weight (g), and Molding time (min) are selected to perform cause-and-effect analysis. Results from the experimental analysis of process evaluation, in addition to meeting the target values of mold temperature, mold pressure, and mold material weight at the mold process, also need to improve the quality of surface cleanliness of the DMA plate at the plasma process, demagnetization on the DMA plate below 2 Gause helps improve the accuracy of the Mold process.
