Why isn't stripping wires by burning with a lighter a more common practice?

We old farts mainly do it to show off our skills to young whipsnappers. Few things are as satisfactory to see a student or new employee ogle at how, with just some side cutters, you quickly remove the ...

Why isn't stripping wires by burning with a lighter a more common practice?

Whether it produces good results or not, wire insulation is one of the worse things to set on fire because "modern electric wires commonly use PVC plasticized with linear Phthalates" as insulation1. ...

What tool is used to crimp DIP connectors onto ribbon cable?

As others correctly point out, you can use pliers or a small vice. I have used a heavy book and just push hard on it, but there is always the risk of breaking the connector or getting hurt (have done ...

Why do LCR meter manufacturers give the details of measurement frequency to us?

They give you the details, because for real-world components there isn't one concrete value; they are all dependent on the operating frequency to a greater or lesser extent. The best frequency will ...

Why isn't stripping wires by burning with a lighter a more common practice?

Well, it can leave burnt debris when you need to solder it afterwards and, even if it does not leave burnt plastic, it can coat the wire(s) with soot from the flame. It can be an easy solution when ...
