Not realy testing equipment but hot air rework station. Works great to remove potting! Put the temp between 100 and 150 degrees so the solder does not melt. You can pick off the potting pretty easy with a razor blade or pin.
It is a Chinese product based on a few chips sold with different brands and very very cheap.

Keep us updated on how it performs.

I have never worked with hot air before. I tried to desolder a big transistor but that seems to damage the board. Desoldering smd components works fine at lower temperatures but still the components get a little brown. For now I am using desolder wick again but some smd inductirs have the solder side underneat than I need the hot air.
So my question is what temperature do you guys use? I found 150 to work well with potting because that temperature does not meld the solder. At 350 I got the burn marks.

Think I learned to use this one better. At 250 degrees I can desolder smd easy. This works much faster than desolder wick.

I go to about 270-280 with no issue, you have to keep moving the wand so not to burn one area. I also have a chip suction device that i connect to the chip first and slightly keep upward pressure on it
as I heat up the pins around it. then it just pops off.

Ok I think I did that too so 270 280 is a good temperature. For the smaller parts the tweezers work good to. I try a suction device for bigger chips.
I have some switcher chips and small breakout boards for modifying the vim of the Marquee. But they are in such a small package I have to make these miniboards first. Will start a topic.
