Quick: what's your best desoldering braid/wick tip or trick?

Since last March 2020, I have been live-streaming three days a week. My streams are all electronics related but include retro computer repairs, soldering kits, Arduino coding, explaining measurements, and other electronics stuff. Several of the recent Workbench Wednesdays episodes have been a result of a live stream. Another outcome from these streams is that my soldering skill has increased significantly. Not just because I am practicing more, but because constantly being watched and critiqued creates motivational awareness!

 

The other day, someone commented that I am a "solder wick magician." Of the things I get called online, I consider that one a compliment. Though, unlike the other names, it may not be entirely deserved. At least, I don't think so. However, as the animated GIF above shows, I occasionally get an excellent wicking action when using desoldering braid.

 

There are only a few tips and tricks that I (think I) actually know. So, I thought I'd ask the community about yours. Getting started, here is something obvious to me now, but people usually get the ah-ha look on their faces when I show them. Unless the wick is brand new, I'll dab it with a flux pen before using it. I find flux on the joint I'm trying to remove, plus the extra flux that wicks into the braid, is very effective. (And a great way to use up old braid.)

 

What are some tips or tricks you have when using desoldering braid (or wick)?

    I was also going to suggest using more flux, but it seems everyone's on the same page with that one. I have a "shoe polish" style tin of flux that I must have got free with something from China. I drag…

    For through hole components, don't bend the leads underneath the board to hold them in place on the top side. That "can" make it more difficult to desolder in the future if needed and the part never stays…

    Use more flux, always....

    ... Aha, I have a lack of chisel tips for the soldering irons I've used...

    For usual soldering work, both types are OK.

    To pour lots of heat in an area in a short time (as you do when wicking), chisel works better (for the same iron) because it can touch more of the area.

     

    I use a small 1.6 mm chisel tip for daily SMD work.

    I have two other tips for finicky work, used when needed:

    a 0.5 mm conical

    and a round one, 45° sloped, 1.2 mm

    It isn't so much about temperature as thermal energy flow.

    Solder wick is a great heatsink. You need high thermal power transfer to keep it hot.

    That means a short, thick tip on your iron to conduct lots of heat from your heater to the braid.

    Solder on the tip provides much more surface area for heat transfer as Jan mentions.

    With long, pointy tips it is very hard to get enough heat flow to the braid.

    Yeah, I can see it, it's the underside of a scalextric vehicle

    Fred, did you post a picture? I'm just seeing an empty box.
