Hi!
Here I have two Hynix HY5DU561622ETP Chips (16Mx16) from my bricked D-Link DNS-323. As I read in this thread one chip from that type is used in the v2.

Can I use these two chips for an upgrade from 32 to 64 MB? Or where do i get the recommended chips best? Neighter Hynix nor Samsung provide any free samples on their website like other companies do (TI for example)

Greeting, Sally

my waranty is almoast gone, so I was thinking of upgrading the memory too..
I can get the transcent memory, for 11 euro only

now I'm wondering, I'm not really super pro at soldering, but I've done it before with a point soldering torch.

How do I get these chips from their wat is it... sockets?
those pins aren't made of tin is it?


If I look at these images: http://www.wl500g.info/showpost.php?...0&postcount=30
then I see that in the 2nd image all the pins are melted away, including some parts of the chip... I mean, it looks a bit rough and very dangerous to do

If someone can explain me how to get these chips off properly without burning them away, I would be happy

The best way to solder/desolder such chips - is to use hot air gun or hot air station. It may be professional (ERSA, PACE), hobbiest (AOYUE-6031 Sirocco, AOYUE-908, etc.) or even good workers hot air gun (Makita HG650 for example) with small nozzle.

Some people upgrade router with an old soldering torch only, but this is not so accurate and require much time.

I strongly recommend you to train on something else before hacking router, for example - old PC expansion cards, motheboards, etc.

Anyway, you have to use good paste Flux (for example, http://www.efd-inc.com/Solder/Flux/ - good, but expensive) and always check quality of soldered pins. Most comfortable is to use stereo microscope, but magnifying glass is acceptable too.
