About power sources getting hot. My friend saved a pic and sent it to me. This is in Celsius.

Seriously though. Get an APS-226.

I just got the fluxes i ordered. Kester951 no-clean flux (2 batches of 3 x 20 oz and got 1 free) and the Kingbo flux paste.

Also went ahead and grabbed solder wick, as well as a spare PS3 PSU < $23.
Is there really no way to test the PS3 PSU i have?

Also a batch of precision tweezers - though i have doubts if they can help me lift those large BGA chips (RSX / CELL) - What equipment do you guys use for that? Was considering a hand-powered or electric pump-powered silicone(?) suction pen, though - what are your opinions on them?

I was also thinking about Dremeling a hole through the bottom of the PS3 right where the fan intake is, and add an AC + fiber lint filter and some rubber height bumpers. Was wondering if that is a good idea - doing it for my PC was quite helpful in keeping the temps down.

you got a reball station?

Getting it in the mail soon - read my previous posts. I do have a heat gun, but.. it's rather dodgy and i don't want to take chances with unpredictable temps when i start repairing other peoples' consoles and electronics.

Also, if anyone can answer my questions, it would be very much appreciated, thank you very much... I am rather new to this rework and reball stuff so i really don't know much, but I can learn, of course.

sorry didn't read that just thought how on earth is he going to place the rsx etc back without a reball station

Been long since i last been here, sorry bout that... Busy with work and stuff. I am working on a new Reflow method, actually much safer than the blower or oven methods... I'll update soon enough

just a little idea but how about adding a poll to show success rate lengths.
it would be good to see how long the majority last for before needing further repair

i think it has been done already...and it's not relevant imho, as you should change thermal compound as soon as your warranty expires, which gives a huge boost to your ps3 lifespan...

I just got my GQ5200 hot air rework station, and tested it out on a few scrapped motherboards. It works well enough, but somehow i don't feel too sure with using it with the large PS3 processors.

Either that, it's a rather time-consuming endeavor, or i don't seem to have the right kind of pick-up tool/s for them (is a precision tweezer good enough, or i should get one of those suction pens / cups) ?


I also did a first reball on a GDDR2 module, and sadly, learned the hard way not to force a stencil off the chip - tore one ball + pad off.. Though, it shows that using solder paste and stencil looks promising as an alternative for when you don't have pre-sized ( x mm.) solder balls.

What hot air temps do you guys use for the PS3 chips, and for how long? I'd like to know because i don't want to be burning them to a crisp with excessive temperature..

That and if you need custom nozzles, etc.

Also, I have both no-clean flux and Kingbo RMA-218 (ROHS); was wondering if the latter was a no-cleaning needed flux as well (i have problems using the no-clean flux; it dries out rather quickly?) or if they won't leave deposits or cause short circuits..

Was also wondering if i could use a heat gun as a fast, (and then) underside-positioned pre+heater on low so i could make the rework/reball process faster..

Recommendations for what to use with hot air rework station when reworking/reballing welcome. Bearing with this because the fancier higher-end IR heater workstation machines are too pricey for my current financing.
