I bought pogo pins to use for firmware uploading.
So I have to make a Jig for my PCB, but this is the first time I use pogo pins. I have no ideas where I have to solder, I mean I want to know if pogo pins have a direction for soldering.
as far as I know Gold surface is for better current conduction so I think Gold end is for contact point, but in this picture It seems silver end is for contact point; I'm a little confused.
- How can I make a Jig for this tiny one? (I use 2.54 mm gap for Test point on PCB) and
- what is the direction of soldering for this Pogo pins?
