I know, because I introduced NAFI at my company. I had moments when I hated
them, because of fretting. Everything is vibrating in a jetfighter at
Mach2, as you know. We had to ask the NAFI makers to modify everything. My
worst mistake ever to buy something before it's evaluated and QPL'd. See,
there is that NAFI guy....they whispered (I exaggerate a little).
Well, we are using them still after 20 years, but now pressfit. Our
pressfit tool works perfectly. Place the connector in the jig, release
secure button, grip the large (1 meter) lever and swoop all 6oo pins into
board within a few seconds. I never thought it would work, but it does.
