    Here is some info on the tip types for the fx-951 and what one is the best to use, depending on the device/package you are working with.

    I have the FX-951. There are so many tips I'm lost.
    The advice from AC0FP is valid, especially with regard to temperature, 680 to 700 degree F
    and solder selection (Kester "44", 63/37 alloy, 0.25" or 0.20" size)
    The difference, for your Hakko FX-951,
    is that Hakko T15 series soldering tips are used by this specific model series.

    You will need a handful of tips. Do NOT make the mistake in believing ONE tip will do everything.

    START by looking at the Shape D tips. These are the flat-blade screwdriver profile tips.
    I like to have a 1/16 (0.062) and 3/32 (0.094) inch screwdriver profile tip for my general soldering work.
    These 2 tips can handle general PC board work (thru-hole) and lugs on controls (switches, pots, terminal strips).
    http://www.hakko.com/english/tip_selection/type_d.html
    I am not an advocate of conical profiles for general soldering work -- I have seen too many conical tips burnt up, as the operator cranks up the temperature to compensate for incorrect tip profile.

    For SMD work, the BCM is useful -- BUT Hakko does sell that T15 tip in North America!!
    So you are left with the BC series

    Depending on your SMD work, the knife, tunnel and spatula (proper size) may be useful.
    http://www.hakko.com/english/tip_sel...d-spatula.html

    You MATCH the profile and size of the soldering tip to your work (Mass factor).
    The biggest mistake are the "knob idiots" --- higher temperatures can NOT solve incorrect tip selection!

    THEN, move down to the SMD tips and their descriptions.
    http://www.hakko.com/english/tip_sel...eries_t15.html
    There are pictorials and some videos to show you how each of these tip series/models
    are used in actual SMD work.

    I'm not a mind reader, how would I know the model of Hakko iron you have?

    We have Chinese copies of the old-school Hakko irons and get the knock-off tips from Circuit Specialists. I pretty much do everything with a 1.6 mm chisel tip. Even the 0.5 mm pitch ICs. Practice, practice, practice.
