| Subject: | "Cold solder?" on Symbios 53c710 on BlizzardPPC |
months ago. My blizzardPPC worked fine for about 9 months since I
bought in January 1999, then in Nov '99 a problem with the scsi
controller showed (I used to disable the SCSI via the 's' key for the
machine to boot, otherwise the machine didn't boot and signaling came
thru the serial port), so I sent it to phase5, when they returned it (in
June 3 2000) they told me (well, p5 was gone at that time, that was
after the bankrupticy) that they did a "cold soldering on the Symbios
53c710 chip" and the board worked perfectly until Feb 2001. In Feb 2001
the board showed again the same problem. This time I didn't want to send
it to DCE 'cause I've heard and read horror stories (Hey, they've had my
board for 1 yr now and they doi not reply) and such things, so I decided
to take it with a Technician, I told him the problem and he soldered the
chip again, that fixed the board, that made me happy for a few days only
'cause the board showed the same problem again after 5 days. (He did a
"normal" soldering...). So my point is: I have to take the board to him
every week so he fixes it :-(... I supose the problem is caused by the
heat the ppc generates or something like that, I tried to put a fan on
top of the ppc heatsink but it didn't work. My question is: Does anybody
know what this "cold soldering" means? Is there some king of soldering
material that's resistant to high temperatures? Is there a special
procedure to perform this "cold soldering"? Has anyone experienced such
a problem? Sorry for my BAD english .
