"Crimping" means forming the leads in some way. Some radial capacitors
for example have the leads cut short and formed with a small "wave"
which
helps them to be pushed into the PCB and holds them whilst soldering.
Just folding the leads through 90 deg to be flush with the board is
not really
crimping and also makes the component much harder to desolder and remove
the component to change / repair.
