Those nasty 42gg, so damn expensive to replace. I have 2 PS4 Slim boards with, presumably, faulty SB. Always nice to see someone hand reballing an IC, great repair!
Yeah the 42GG failure rate combined with a limited number of pulled parts is going to be an issue soon. Many of these slims will simply not be repaired I would imagine.
@@ToltecMerc I’ve tried them both my chips 2x now. Reballed too. I even bought a slim with a FW issue that I robbed the 42gg from. It installed flawlessly, and worked. Confirming my suspicion that my chips are DOA. I don’t think it’s my technique. I think my technique is good. I’ve even repaired a slim where 99% of the solder mask on the board was gone. It’s flowed down and worked to my surprise.
To be honest, it is a cheap Chinese generic 1080p camera. So cheap it does not even have a name on it. It does get the job done though. Thanks for watching!
I know you are probably aware but there are stencils for southbridge chips. Seeing how expensive those ICs are right now and how salvaging them from other boards is a thing right now it's worth buying them for saving time. With stencil it takes just a couple minutes.
Hmmm. I'll look for it on eBay. I have a stencil for the South Bridge but not a very good one. It has a full grid of holes where there are some pads skipped on this 42GG. But yeah I need to find a good stencil. Thanks for commenting!
@@ToltecMerc What I do is use that stencil to place the balls on the IC using a thin layer of flux as adhesive... remove the stencil and manually remove the 6 balls from the not populated pads on the 42GG. It's more time saving than manually populating every pad
Exzellent work, sir! Thank's for sharing! The Southbridge looks to be a common problem on all models and really hard to fix. Congrats for that one! Really high skillz!! How many hours did this take aprox?
Great work. I do have a question though. Just for knowledge sake, how many ohms should you be getting to know that the capacitors under the southbridge is good?
There are 3 temps of solder paste / balls found. 138c, 180c, 210c. With your experience would 138c solder suffice for bga electronics as low heat to fix it will definitely give it more life. You should get a professional reballing set, you could lift chip / reball in 10 minutes. Its pretty cheap when compared to the time / stress you are taking as this is a routine.
I have not had a lot of experience with BGA work. I'm still learning myself. The solder balls I am using are standard Sn63-Pb37 so I assume they become molten around 170C. I have not tried lower temperature balls. I'm sure they would be easier due to the lower melting temp, but would they be too soft? I have a reball fixture that I don't like very much. I use it on APUs but on smaller BGA, sometimes I just prefer to do it by hand.
@@ToltecMerc every one uses standard 180c i guess. But processors do get to 80c right; and sometimes 90 100c when cooling fails. So i guess low temp bga might cause permanent damage in those places. Since southbridges dont have any thermal pad or any pressure on them, i was having a doubt whether low temp balls would work. Anyway thankyou for the input.
You replaced some solder mask under the south bridge. Is this common to do or does it happen if to much heat is applied. First time Ive seen you do it. Thanks 😊
It is somewhat common. It is usually damaged by scrubbing to aggressively with the solder wick trying to clear the old solder. It’s a good idea to repair it so the solder balls stay in place and don’t try to flow elsewhere.
Great work..But i have an issue where the ps4 powers on and working fine but there is no light on the power button. Should i replace the power button circuit board?
It could be the PCB with the buttons and LEDs or the flexible ribbon cable that connects it to the main PCB. You could probably find both as a set on eBay.
I do like the new lamp. I can't say I have timed it though. It does turn off automatically though after 20-30 seconds. I add some heat from the hot air gun to help speed curing. Thanks for commenting!
hello sir, I find the repair you have done very interesting but can you tell me where to find the same pliers as you pls? She looks very fine for such microscopic work. Thank you PS : this is a translation from French to English so I hope you understand because the translation works badly sometimes. thank you
I'm having something similar but if it gets more advanced than just replacing the Power supply I'm screwed 😮💨 I just personally Changed Thermal paste and cleaned it as well but carefully put everything back and some idiots Put the wrong screws in one and I'm missing screws I hope it wasn't shot so bad it fried what you had to replace or I'm done for
What's you secret to hand re-balling? By that I mean the airflow. I can just image spending a nerve wracking hour getting all the ball perfect and then blowing half of the off the chip!!! Urrrrrrrgh. Also, you had a UV light on the PCB, but did not document why. I assume broken pads or traces under the chip? I would like to have seen a lot more detail on that and what UV glue you used and how you applied it.
I flowed the balls into place with 400C heat at very low airflow. On my Quick 861DW I think i was using an airflow of 10 out of 120. At that low speed, it has more of an oven effect. I have had my share of solder balls flow together. It's usually because of too much flux. Very frustrating on an APU with so many freaking balls! There was some solder mask damage on the PCB. I think the SB had been replaced before. If you watch just before the light, I am applying some Mechanic LVH900-GY solder mask with a needle and tweezers. Sorry it was so fast but I have to speed it up because most viewers attention span is not that long.
@@ToltecMerc Thank you (I could watch that part in regular speed). I have yet to try it myself. I have the same Quick air station and I have had the infrared (hot plat) heater for a long time. There is one BGA part, on boards that I work on, that I need to get up the nerve to change myself. It is a PowerPC processor. It's not real big. I think the big problem it has is bad connections and that may because of lifted pads. MiniMicroStencile has been able to get a number of the boards working for me and their price isn't that bad; just a 2-2.5 week delay between tries. I think you must not drink coffee, at least on the day you do the balling.
Pls what can I do I got my ps4 slim 2 month ago just 2 weeks ago I had to change the PSU due to the game won’t turn on just a beep with blue light and turns back off after I replace the PSU the game works cool now I’m having Same issues again I’m scared of getting PSU.. so is it possible for another internal component like motherboard should be making the PSU damage ??
Hey sir, I'm having trouble with a ps4 that has WLOD I've replaced the hdmi and ic chip a few times and I don't think they are the issue, as I'm not finding any shorts on them or by them. I actually can't find any shorts on the board. Just wondering if the southbridge can go bad without it showing signs of any shorts? I'm quite in a loss here, I'm not sure what is causing the issue and thought I'd ask before I attempt to reball the southbridge myself
I can’t say that the South Bridge will never cause a WLOD, but I will say it is very unlikely. Have you checked the filters between the IC and the port? Perhaps the fuse that supplies 5V to pin 18 of the HDMI port? Any missing resistors or diodes near the port?
@@ToltecMerc Thank you for the response! I've checked the filters they seem to be ok, I don't see any missing reisistors or diodes, but I did replace one of the resistors as it had continuity whereas my other boards showed it shouldn't have continuity. relpacing it regardless didn't change anything. I will check the fuse again for pin 18, but one thing I did notice is that pin 18 gets short to ground once turned on but not when it's off and I've traced pin 18 all the way to syscon chip, from where the short is coming from. I'm not too sure if this is normal, do certain components have continuity when the system is turned on? it reads 0.0v all the way to the syscon but it doesn't when turned off in diode mode
I don't mind to the South Bridge by hand but I should get a good stencil. I have a stencil for the PS4 APU. I'm not doing the APU by hand! Thanks for stopping by!
