Hello all,
I have a small assembly with two PCBs forming a sandwich. There are rigid components that mount between the PCBs and keep them 17.5mm apart (these parts are bolted to the PCBs).
There are some through-hole resistors that are also mounted between the PCB sandwich (a resistor has one lead connected to each PCB).
At the moment there are plated through-holes for the resistors but I'm worried about stresses on the solder joints as the parts expand and contract with temperature. The resistor body is 10mm, so there is only a little of the lead to add a kink for stress relief.
The resistor leads are long enough that they could go through one unsoldered hole and be looped back through a plated hole and soldered there. The loop would allow a bit of springiness for stress relief.
Any better ways of doing this?

It might matter for hot running power resistors but not for small signal devices.
One easy thing to do to help is to use a better solder which is more resistant to cracking.
