While browsing for more robust solutions to those plastic dupont jumper wires, I came across these wires:

enter image description here

The datasheet didn't really provide any information and I haven't come across these wires yet. I was wondering how are these applied to pins. I have 0.64mm square / SMD pins on my board. Do you just slide them over for easy reversibility or do they have to be pinched with pliers or perhaps heated?

    \$\begingroup\$ These are for testing and prototyping, not for production. So yes, "you just slide them over". \$\endgroup\$

If you remove the plastic piece from your everyday jumper wires you'll find a small metal piece pinches on(seen in picture below). This is the exact same thing instead that over the metal piece is heat shrink instead of plastic enter image description here
