| Abstract | This paper presents techniques that improve the productivity for printed circuit board (PCB) drilling by laser driller machine (LDM). The goal is to reduce the process time for a PCB workpiece. Applicable techniques include reducing the number of Galvo tiles, and path planning improvement for either tiles or holes. The non-crossing path approach proposed in this paper generates a shorter path for both platform positioning and drilled holes in tiles. This paper also suggests that a tile with more than 550 drilled holes should be separated into some segments to ameliorate the computation time of the whole path planning when using this non-crossing path algorithm. In our experiences, the moves and the settlings of the Galvo tiles dominate the efficiency of production. That is, reducing the number of Galvo tiles that cover all holes becomes paramount in productivity improvement. The typical workpieces with 11,760 and 28,026 holes are treated in a real process by LDM to evaluate the efficiencies of the proposed techniques. Results show that the reduction method for the number of tiles and the non-crossing path algorithm for both tiles and holes can increase productivity by approximately 16~17%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
