fuses are trial and error, so not much help there
chanical stresses on the fuse. The current fuse is leaded, and the assumpti on is that the stress comes from the very thick leads. So one idea is to mi ll some of the arc geometry, so that the PCB suppport in the pad is angled to the direction of the fuse (that way forces are transferred to the PCB in stead of the fuse itself)
curl is not enough
use design?
Yes, it does.
Right now we are planning thermal tests, running with a fuse that is mounte d on the PCB with self-adhesive tape, so no stresses on the pins (if that f ails, all other tests are futile)
For reference, other samples are mounted with 90 degree bends, others with curls, even others with milled PCB slots around the pads
