    I working on some projects and I was thinking about using magnet wire instead of sold core wire ... I like using magnet wire because it has a smaller diameter and in my opinion it looks nicer and neater.. My problem is do I use 20 awg or 22 awg ????









    Thanks

    Depends upon the current level and voltage drop you want. For most standard circuit wiring 22AWG or even smaller is fine. When they used to do wire-wrap connections on circuit boards the wire typically was 30AWG.

    All the magnet wire I have IS solid core (enameled single conductor) ?

    What do others use to strip/prepare enameled wire?

    That's one tool I don't have.:(

    I've noticed some factory prep, that looks like it was rotary brushed.

    I have use sand paper or a knife but the stuff I am using is from a company called Temco and there is no need to clean the wire before soldering ...

    Check it out

    30-AWG wire-wrap wire is easy to use. Strip off the insulation using a wire-wrap tool WSU-30 from OK Industries.

    Thats how we did it at work, wire brush. But much of the new wire has "solder through" enamel now. Soldering heat dissolves it.

    I use the same exact tool for the same exact reasons as MrChips does.

    Just what is a magnet wire ? :eek: Is it just a Enamelled Solid Core Wire?

    Yes, it is.

    Yep. It is commonly used in magnetics (catch all phrase for inductors and transformers) where size is critical. The enamel coating takes up little space in the winding, and after it is wound the device can be flooded with varnish as further insulation, a step that takes no extra volume.

    It's quite fascinating process, both the design and the manufacturer. In the power supply world most magnetics are custom designs, specific to a single design.

    I wouldn't use it for prototype use, but it's not my build.

    I can't imagine trying to use insulated wire to jump across the .1 inch pads on the back of my prototype boards. Trying to strip the insulation with a bunch of .03 inch doughnuts left on the wire is almost impossible.

    I just use my pocket knife to strip enameled wire. Not Mil-spec quality, but it works for my stuff.

    @#12, wouldn't just using the core out of the insulated wire work better/easier for that? I can imagine the"donut" scenario easier than removing the enamel from a short piece of magnet wire. :)

    The copper from an insulated wire will work just fine. You can usually find a sufficient size conductor in a stranded wire.

    Can you really imagine doing this with an insulated wire to jump from pad to pad on a prototyping board?

    You didn't ask me, but here's my answer. It's much easier to follow wires of different colors in complicated prototypes. I use black for ground, red for power, and six other colors for signal paths. Using nothing but enameled wire wouldn't work for me.

    For Strip board prototypes etc I also pick up the bundles of a 100 insulated hook up wires off ebay. $1.20/100 postage paid.

    Because I use the same wire and tool pictured back in post #7 and can have both ends of an insulated wire stripped long before anyone else can even get their pocket knife out of their pocket.

    And yeah, I have 10 different colored wire too. Plus uninsulated bus wire.

    No, I thought you were talking about one single "donut" for going to an adjacent pad. I use telephone "trunk" wire myself, many colors in the bundle and it was free.
