I have a footprint on a ~100mil thick PCB for an SMA edge connector:
I find millions of SMA edge connectors for 62mil board thickness and I found a single one for 32mil (https://www.adafruit.com/product/1864).
However, I found none for ~100mil thickness.
Do they exist? And if not, is there any hack to still install an SMA connector reliably? (Frequency range is up to 3 GHz, RL as good as possible but not critical; price secondary).
It is worth to mention that the PCB is already fabricated with the footprint above. That means I cannot change footprints, holes, thickness etc.
This is the Tyco Electronics 2-332004-0: 5/16" 1/4-36 Steel Hex Nut

There are a couple of styles of SMA edge-launch connector that are very flexible about board thickness.
This type was I believe originated by Southwest Microwave, but is now available from a couple other vendors:
This type originated with Rosenberger:
But either of these types has lots of parts so it will be very high priced for a 3 GHz application.
Why not just use the old standard through-hole right-angle type?
The pins are typically a bit over 100 mils, so you shouldn't have trouble soldering them. For best signal integrity, mount this type on the opposite side of the board from where your signals are routed.
