TIP: Making connection to 0.5mm spaced lands/conductors.
A much better solution , I picked up some surplus new of these
"gigabyte 12CF1-1id133-61r" computer cables.
..025 inch spacing cable for 0.1 inch headers , as inter-line ground
wires and extra bridging IDC prongs inside the headers.
Anyway ribbon is 0.635mm spacing with proper copper conductors (so heavy
to the handling) , so its quite easy to strip off the insulation, at an
end, after unclamping an IDC. Solder a 5 way strip at a time , as not
0.5mm spacing and add lacquer insulation afterwards.
