I am in the manufacturing of bare pcb boards. Lately I have been having shifting problem in the drilling section. Sometimes its just a few holes that's shifted. Sometimes its random shift. Observation shows the shifting happens more on the smaller diameter holes, 0.65mm to 0.80mm. Glad to hear any suggestion that can help me overcome this problem.
