Desoldering Falcon NVRAM

[mikro]

Falcon 030: Alternate+Control+Right Shift+Undo

No need for Right Shift.

...during boot, before RAM test.

Totally OK also during RAM test.

My video was done to try and prevent damages to the boards as a lot of people are not good at this stuff. Sure more qualified people could do different methods.. but as many found, including myself, using a solder vacuum can easily damage pads, its why I avoided it in my video. Cutting pins and doing things one at a time means people will not start levering the NVRAM with a screwdriver, breaking the motherboard, ripping vias out etc when the NVRAM doesn't come out freely. I've fixed many boards due to such damages.

No objection if you want do a video, but have to think about who are not good at soldering, and how they will likely damaged everything, every step of the way. That is why I did the video, and the methods I did.

When opening my Falcon, it turned out the Dallas chip doesn't use a package with pins that could easily be reached (and cut):

Any suggestion how to proceed here?

Cut the case off..

@exxos , when I removed mine I believe it was one of the turfiest removals I've done. The ground pin was horrible. The ground plain must not have thermal relief. I'm guessing its just a hole in the huge ground plain that sucks off all the heat. Was a real pain. Great video which gives people a warning and howto deal with situation.

@PaulJ yeah the gnd pin takes a lot of heat. In some cases it took my gas iron and soldering iron to remove it.

Yes, I had to borrow a board heater that sets under the board and brings board temp up close to solder melting and then use wick and an iron on top with more solder and flux. I really believe it was the worst extraction I've ever done.
