发明名称 VIBRATION COMPENSATION DURING TRIM AND FORM AND MARKING
摘要 A method for forming indicia on a semiconductor device package, such as laser marked or ink stamp marked indicia. The method can be performed on an apparatus, such as a production apparatus, which forms the indicia as well as performs semiconductor device trim and form operations. An embodiment of the present teachings ensures that the indicia marking process at a laser marking station does not occur simultaneously with the device trim and form operations at a trim and form station. Trim and form operations, particularly using a ram press, can impose vibrations on the laser marking station. Ensuring that laser marking does not occur simultaneously with trim and form operations removes the negative effects of vibration on the laser marking station.
