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.

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.
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.
analogrocks: Those are pretty pictures! Set one up running a ps1 or NES and sell them as retro gaming projectors. OR post them to me. Just put the stamps in the corner. Should make it just fine

iwwy1969: Hi all. Nice forum. I have Onkyo TX-NR616 no sound and no usb access. I have 5v at usb. I found that oscillator close to DSP is not working. It has no voltage feed from DSP. During the testing through display DSP shows version D??? .

lfcfan: Hi Todd, have been reading endlessly about the topic, and I really don't think that I'll be capable to 1. do the job myself as I don't have enough of the right equipment, and it looks like only the people who have access to TI exclusive distribution networ
