Hand soldering MillMax 0900-3-15-20-75-14-11-0 Pins

Hi
I want to hand solder this 0900-3-15-20-75-14-11-0 Pogo Pins on my PCB.

But i guess it would be a problem(haven't tried yet) to make them stand straight on my PCB with hand soldering.
So question is do i need any kind of support or something to hold them straight while i solder them?

Is the pin magnetic? Can you hold it in place with an electromagnet?
Or, if you use a permanent magnet, be aware that very high temperature weakens it.

Do you need to install several pins aligned in a row precisely?

these are surface mount pins
they will go on your PWB as in the picture

make a template from your pwb with a drill hole, at the location of the pin,
and that will fit over the pogo part to the shoulder of the base
use the mounting holes ad some standoffs to hold the template in place.

solder paste on the board,
place the pin
put the template on and tighten down the standoffs
use a hot air rework station to solder the surface mount pin

should work with any number of these pogo pins on a board

Thanks for reply!
These pins are non- magnetic.
I tried just putting some Solder paste on the PCB and place pin directly over it and warm it with Soldering iron. It works but wont say these pins sit completely straight.
I guess that has something to do with amount of paste i used, if i use less paste on pads then i think i will get better results.

when you warm the solder paste, are you warming it equally all around the circle?

you might use something like an ov-glove (glove style pot holder) to push
gently down on the top of the pin
since the verticallity matters, how accurate does the xy position have to be?

 

[jimmykk]

No, unfortunately the heat i think is not spread equally around the circle, i can try with a soldering gun.
XY (guess +-0.1mm)needs to be quite precise, as i have to make the mating pads smaller than recommended size.

try making a template to fit over the moving part of the pin to the non-moving part
about half way in the photograph, where the diameter changes (see post #3)
this should hold the pins in place

have you tried re-flow soldering?
