I'm looking for some guidance here and would appreciate input from some seasoned professionals. I am the Op. Mgr. for a medium sized electronics contract manufacture, but my background is almost exclusively in the machine tool industry and I would like to get an "outside" opinion on an issue that we are having. We have a two JUKI SMT line. Both machines are well maintained and in good overall condition. We are a job shop, so, we get a fair number of new jobs to set up. My programmer does the programs manually (using customer supplied X - Y location data, when available)then insists that it is necessary to step through each location visually on the machine, using a bare board, to verify the locations. This can be a very time consuming process, especially when you have six or seven hundred individual placements on a board. My question is - is this standard in the industry? Does everyone do this? I appreciate your input..........
