Roland 80017a Chips Removal - GR-700 MKS-30 Juno 106
YouTube Uploaded by WayneJoness on Apr 11, 2012
"http://www.joness.com/gr300 This video shows the removal of a 80017a chip from a GR-700 printed circuit board. The tools I used were a Radio Shack 30 watt soldering iron, desoldering wick, soldering helper, and Caig DeoxIT D5. The basic Radio Shack 30 watt soldering kit has almost everything your need. I find that spraying the Caig DeoxIT D5 between operations helps keep the PCB clean, and helps the old solder flux move on to the desoldering wick. After I have removed the solder from the pins, I used the soldering helper to line the pins up, then gently rock the chip back and forth to make sure everything is loose. Rather than pull the chip out, I first push on the pins on the soldering side, then gently tug at the chip. It comes right out. If you have not tried this before, I recommend practicing on some spare parts, as this can be tricky and frustrating."
