Solder some thin beryllium copper strips onto the microstrip so that
the springness holds down the flat leads of the device onto the track.
There's little extra fringing effects then. If you're testing thousands,
just make a simple pick and place gadget that picks the transistor out
with a vacuum tube, holds it down against the pcb for the test, then
places it back into the packaging.
