SMD pin numbering?
For 3,4,5 or 6 pin SMD packages, too small to have a dot identifier, what
designates pin 1 ? Printing orientation ? eg top code marked reading, say ABCD with pins coming off over and under along the long sides. then pin 1 at corner nearest the base of the "A" towards D, round as in standard DIL packages , to above "A" what about marking AB CD where long dimension is vertical and pinning off to the sides? pin 1 nearest "A" still, then towards C ? |
