SMT Pin 1 Marking
(1/1)
admiralk:
This might win the prize for stupidest question ever, but this is my first time trying to solder SMT parts. I went to put a 74HC595 on the board and did not see a dot or cutout to indicate pin 1. There is a bar on one end, though, that I would logically assume for pin one. Is that the pin marking, or just part of the graphics?
And just for reference, I attached a blurry picture of the chip.
mc172:
Yes, the bar/line indicates where pin 1 is. The package has also got a chamfer on one side which confirms pin 1.
admiralk:
Much thanks!
I won't tell you how long it took me to find the chamfer. :-DD
