Effect of Cutting Parameters on the Quality of Micro Drill Process Results on PCB (Printed Circuit Board) Products

Abstract


PCB (Printed Circuit Board) is an important requirement in the world of electronics. Currently, printing PCBs is less efficient because the time required is quite long and the manufacturing process is also less efficient. This study analyzes the quality of the machining process of PCB products with tools 0.8 mm which includes the quality of the hole dimensions. Data collection was carried out with variations in spindle rotation and feeding. The hole quality analysis method used includes analyzing the accuracy of the hole using a microscope. The results of the analysis show that the accuracy of the hole dimensions has changed significantly in some tests. Tests were carried out with spindle rotations of 5,500 and 5,600 rpm, and the feeds used were 160 and 170 mm/min. In this study, the largest value obtained was 0.82 mm at 5500 rpm and 160 mm/min and 170 mm/min and the lowest value was 0.80 mm. This research provides an overview of the quality analysis of hole dimensions on PCBs. The results of the study can be a reference for the development of Micro Drill on PCB material by varying more machining parameters used, type of cooling media, tool shape, tool type and measurement method used.
