After reading more about the Wurth Redcube Press Fits, it looks like they may be my best option. My original concern with them was joint strength and connection resistance, but according to the docs:
Pressing the pins into the PCB, a high friction between pin and plated through-hole generates a
homogenous cold-welding between the pin and the copper plated via in the PCB. This results in a
gastight, strong mechanical connection with contact resistance less than 200 µOhm. No other
technology transmits currents up to 500 A with such low self-heating.
With regard to long-term reliability, REDCUBE PRESS-FIT is an improvement since it has the lowest
FIT value (Failure in Time) of the overall system. It is up to 30 times better than the FIT value of an SMT
solder joint. A single solid press pin has a typical extraction force of 100 N for 1.6 mm PCB. So a small
component with 8 pins could withstand a weight load of an average person without extraction out of the
PCB.
Thanks,
