Heatgun Reflowing

[Crack Kills]

I have been searching online, and was wondering if you guys had any personal tips to the process? Gilksky's method reflows the bga's and the 2 chips next to each, all the others don't.


I'm not going for a reball because I'm not near that technically inclined, nor do I have the machinery, and I'm not paying any more than I have to for a system that should for all intents and purposes still be running strong. I don't play it much and usually give it a cooldown period after every few hours of play.

Any tips you all can provide that seem to have worked better, ie amount of time the gun is spent on each chip, and the most ideal temps you have found would be appreciated.


PS. Also the system I have is at the GLOD stage where it will even still come on for a few minutes before glitching out and freezing and going GLOD for hours until fully cooled. Could i just need some new thermal paste?

System: CECHB 20gb BC model

i jsut got the ylod today, so i put tmy ps3 boardi nthe oven for 10 mins came out nice and workingg.

aren't there alot of components on the mainboard that shouldn't be heated to that extent though?

any chance you could message me how to do that and what exactly is done? thanks, i had already sent my ps3 out to be reballed and after a month got the ylod again, the guy said he just reballed the GPU

I wouldnt put the board in the oven,
1. its not guaranteed to work
2.Board might flex and/or bend even if you dont move or touch it during cool down
3.Heat guns arent that expensive
4.Reassemble is a lot easier as dont have to remove as many thermal pads(thermals pads once they become old become more brittle over time.)
5.Less cool down time and easier to control what exactly you want heated
6. This might also cause other thing to malfunction when even if the ps3 works again
(example the ylod ps3 i just fixed when starts to get up there in heat starts to lag and freeze when reading hdd cause of the oven heat to the other parts)

I myself just recently fixed a ylod ps3, i didnt have a heat gun at the time and tried the oven method myself(after removing all thermal pads stuck on the board) 425 for 10 minutes. Reassembled and still ylod

So i ordered a grizzly heat gun from amazon about $16+7 shipping
Arctic silver from radioshack $9.99

Got the gun and heated up the board, reapplied thermal paste , reassembled and boom working

I will leave a little note when reapplying the thermal compound it has been repeated over to leave a thin layer but that doesn't always work. My fix was:

1.Put a thin layer of thermal paste on the bgas
2.Put heatsinks back and tightened down
3.Removed heat sink and checked the back to see the coverage from each bga
4.Check to make sure you have full contact and coverage, if not then
5. Put a small dot of arctic silver where the problem areas are
(example if only edges are getting contact put 5 small dots on the bgs 1 in the middle and 1 close to each corner.
6. Tighten down heat sinks agn making sure that there is no spill out.
7. Enjoy ps3 not saying its overheated every few mintues.


Naataq just get a heat gun then search google for gilksy guide

reflow should only be considered a temporary solution. you'll need a reball to atleast fix the problem for a considerable amount of time.

i believe the oven trick works fine, i actually got faster load speeds and hd transfer speeds, after i putit in the oven, i used good themal compponmd so i hope my machine lasts long.

I still don't trust the oven method so since I have a heatgun already I'm going to try that first. Only problem is my heatgun only has 2 settings:
250C/482F Low Fan
450C/842F High Fan

Since most of the guides say use the lowest fan setting possible, how long should i keep the gun focused on the processors?

Happend a few times on mine.
Best method i found & is still workin after a year is to use a paint stripper heat gun.

Cleaned all chips & bits with plasma screen wipes.
apllied flux to all areas that was gonna be heated.
set heat gun to 500c, heat area for 1 min keepin the gun moving at all times.
leave alone for 15 mins DO NOT TOUCH OR MOVE.
Turn board over & do same procudure.

Apply a good thermal paste, i did a mix of the of silver & white, spread all over ( only needs a thin layer ).
Re-assemble & job Done.

500c???? that would melt a hole threw it. u mean 500f, anyway, its been a few days and my ps3 has been on 24/7 no problems. i put 4 120,, fans exhasuting all aroudn the top and back.. seems ro run faster, bettier will better fans..
