Ram Upgrade

[bam]

although reflow would not be needed if we were to get some flexwire to hand solder the chips

I have access to a reflow oven(programmmable) however quick question does the board have components on both sides?if the answer is yes this may be a problem.

yes, the boards are multi-layer double-sided, so sticking them in your oven would probably cause ALL the chips to fall off the board :-)

Will one of you kind colonial cousins please explain what "flexwire" is.

I'm just bumping this thread again... it'll be nice for my 5600 to get a RAM upgrade, 32M to 128M...

Maslovsky, can I send my Zaurus to you? how much will it be for the upgrade?

Or maybe somebody else in West Europe...

I just wrecked my 6000 - snapped a DRAM chip when reassembling it (yes, I could weep   ). Looks like I'm going to be the ideal candidate for a trial RAM upgrade, on the basis I have nothing to lose

ok, now you're really scaring me

I have taken a look at my SL-C3000, it has the 561633F chips in it, but I haven't any access to a shop that could replace it.  I don't know of anyone in the US doing this.  If any of you know anyone who does this, or who might be talked into doing this, well, I'd sure appreciate it if you'd let me know about them or maybe give them my email address.  With all the spam I get, it'd be a lot more reliable to give me their name.

I know I couldn't do the swapout myself, darn it.  I used to be a pretty good solderer, but that's ancient news.

you need access to BGA surface mount assembly as this device has a "Ball Grid Array" of solder balls... removing the old device, cleaning the board and soldering on new ones is far from trivial.

the 6000 takes an older version of the same chip - the 561633C variety. I *think* the only difference is power consumption and speed - possibly also the F is lead-free due to EU regulations on use of hazardous substances coming into force in July 2006.
