Double Segment Polarity Mark

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

If there is room, add a short ss segment to improve visibility of the pin 1 polarity.  EG for DIOSC95P205x160x80-4N  Place a short silkscreen line segment, the length of pin 1, just above the upper silkscreen line by pin 1 (like a double line).

	We have decided that on many component families there is no room for double silkscreen outlines for Polarity Marking. Instead, the new standard is the "Lack of Silkscreen" is the new polarity marker. Can you look at this QFN picture with the physical component installed and tell me where Pin 1 is? Nice solution for bottom only terminal parts and micro-miniature packages.
