Oh, you lifted the "PAD". If there's a via linked next to it, then you should be able to link to that. I can't see clearly. But if there isn't... then I would say no. But there are people here with more hardware experience than I, so Kaos may chime in if he can. Quote Link to comment Share on other sites More sharing options...
Fringle Posted August 29, 2023 Report Share Posted August 29, 2023 (edited) Via for that pad is under the ram, I've circled it in yellow. You might be able to get a way with wiring a jumper wire to R6B8, also circled in yellow. Edited August 29, 2023 by Fringle Quote Link to comment Share on other sites More sharing options...

Marty Posted August 29, 2023 Report Share Posted August 29, 2023 ...and where's the pad? I can understand a lifted pad, but this one is completely missing. Quote Link to comment Share on other sites More sharing options...
lopenator Posted August 29, 2023 Report Share Posted August 29, 2023 (edited) Its probably in your steel wool lol. You should use hot air and pull the chip off so you can attach to the via. It doesnt matter where it is, its gone so you cant use it. Edited August 29, 2023 by lopenator Quote Link to comment Share on other sites More sharing options...

I always feel like when I use hot air to detach a RAM chip, I'm destroying the chip and anything around it, like SMD components. lol. But I'm doing it perfectly fine. Heat scares the shit out of me. I would try the component that was suggested to be connected to the pad and the via. I dunno how you're gonna get a wire beneath the chip in order to solder to that via. Just make sure you solder to the side that comes before the component. Quote Link to comment Share on other sites More sharing options...
lopenator Posted August 29, 2023 Report Share Posted August 29, 2023 (edited) If you have a good rework station and know what youre doing it wont destroy anything. Thats what theyre made for. ....then again he pulled off a pad so also those ram chips take alot of heat to damage although its possible to do so Edited August 29, 2023 by lopenator Quote Link to comment Share on other sites More sharing options...

Only way they're gonna get on the via and still be able to attach the Ram is using 38 AWG copper wire or smaller. It would be much easier to go to the resistor assuming they don't knock that off too.

I'm paranoid that the ones I'm salvaging from other boards wont work because I'm using heat, which I know is stupid because it requires heat to install them in the first place. I use 350 degrees so I barely use enough heat to remove the chips. It takes almost 2 minutes to pull them off running the narrow tip around the legs only... Should I turn up the heat so it comes up quicker and I'm not applying heat for so long, or should I keep it where it is and just be patient? I'm wondering if a longer duration and lower temperature is better than a shorter duration and a higher temperature. I'm fucking scared I'll fry something. I guess a longer duration would preheat the board more effectively. Quote Link to comment Share on other sites More sharing options...
lopenator Posted August 29, 2023 Report Share Posted August 29, 2023 350c and about 2 mins sounds about right. I like to run mine with 6.5 air flow when removing chips of similar mass. You are not destroying anything. Just be mindful of plastic parts around the area. Quote Link to comment Share on other sites More sharing options...

Still attach to same resistor but other side of it. Quote Link to comment Share on other sites More sharing options...
Marty Posted August 29, 2023 Report Share Posted August 29, 2023 Yeah....I think OP is off on a "journey of discovery" at this moment. May the wind be at your back and your solder flows freely, intrepid modder. 1 Quote Link to comment Share on other sites More sharing options...

Run a simple jumper wire awg30 from the pin to the via I marked in my picture and you are good to go. 2 Quote Link to comment Share on other sites More sharing options...

herooftheday Posted September 30, 2023 Author Report Share Posted September 30, 2023 (edited) i did not try it again but I gut a "broken" xbox off ebay and put the ram on that one but it is still kicking ^^.

herooftheday Posted October 1, 2023 Author Report Share Posted October 1, 2023 (edited) I did it two weeks or so ago. Both work I used my how air station to pull the old chip off and bought new chips to be sure, but both work the one with 128mb with an xenuim black ice with led mod and the one with the lifed pad with a aladdin clone.

herooftheday Posted October 1, 2023 Author Report Share Posted October 1, 2023 only one question for the aladdin xt clone can I put on it xblast plus cerbios, currently I only have cerbios on it. I saw that on github aladdin-xt-cpld would that work? Quote Link to comment Share on other sites More sharing options...
