ASSEMBLED IN CHINA :P

How much would it cost to fix, because I have the same problem on HP 6735s laptop

Thanks

This can cause permanent damage to the chip. You are not using a thermal profile. You can blister and delaminate the chip/board.

If you are going to reflow chips, do it right, but stop giving people bad advice.

Thanks for the obnoxious song instead of letting us hear what hes saying.  SOOO MUCH BETTER AND NOTHING LIKE IT ON YOUTUBE BEFORE!

A few basic questions:

1. How many IC reflows have you done using this technique, and

2. What is your success rate

I do 20 to 30 a week, with a success rate b/n 92% - 96% with 6 months warranty.

If a job is returned between 1 week to 2 months, I class it as temporary or not successful

Nice cooling system. How much did that cost?

[prep044]

sweet, lets just let everyone touch my south bridge while its getting reworked.

[plentyoflife]

Very cool, tel me where did you get the hermal camera???

[int0x13]

Two questions:

1)which tool are you using for what you call "PCI lane traffic test", oscilloscope?

2)what is the model of your micro soldering torch? are they some better than others for bga reflowing?

,regards, thank you

@int0x13

1. For PCI test we ran hard disk tool to find the right interface which causes this error. Unfortunately PCI was working correctly, so the problem was somewhere else.

2. I do not have any model for soldering torch. I neither recommend it to be used for BGA rework, because there are professional tools which are much better and safer.

Congratulations

Perfect performance!

What camera are you using?

[babylonxgr]

I have been using a reworking hot air station for some time now but even though I almost always succeed with cold connections under any BGA IC, in many occasions the cold connection appears again after some hours of usage. I realized that most of the times, the problem reoccurs with higher temperature ICs like VGA or northbridge. I always pure no clean flux under the reworked ICs while heating . I clean as much as I can with isopropyl alcohol.

I cannot explain this! Can you?

[WalleMotions]

@babylonxgr It is a well-known fact that when a soldered connection breaks, corrosion will start immediately which will prevent good rework. So it is not recommended to repair BGA soldering with reheating and flux. Reballing is always required to make high quality rework however there is high possibility of success if temperature can be raised much higher than melting point, but it can cause permanent damage to the IC.

So I am sure that corrosion makes reworking unstable.

May I know in the first place how do u know it is the South Bridge is the one at fault?

why didn't you suspect the vga chip?

[ppkerobotics]

@leboch65 First we expected that the VGA chip causing this problem but further memory and PCI lane traffic tests showed that only one bit is toggling unexpectedly on data path which also caused recognizable error patterns on screen. Bit error simply disappeared when we pushed the south bridge with a small pressure.

hello i'm looking for the similar model of the "pdr ir 1600". Do u have document or manual, to show me how to use the infra red and all thing around the rework station, like the camera, the vacuum etc..bye

Bonjour, je recherche le modèle équivalent du "pdr IR 1600", Avez vous un document ou manuel d'utilisation, pour me montrer comment utiliser l'infra rouge et toute chose autour de la station de reprise (station de refusion)

[anatolia8386]

hepsi dagınık ben de öyle tabiki:)))

[web7days]

I have bought the same blow torch ( it is from Taiwan) but I won't have the thermo camera... however I have the temperature gun. I would like to give it a try on a NB motheboard...later.

[mixcatcom]

Awesome stuff.. I also run a computer shop, I need to give this a go.

All the best!

Very cool boys. I am always happy when watching something worth like this. Big THANK YOU!!!

[jasminaura]

just wanted to say, you're cute :) lol

but you can invest a little money for a hot air / smd rework station.. lotta chinese made ones out there for cheap :) cheers

[dancdt]

please tell me the name of Thermic camera? what model and how much does it cost?

[ppkerobotics]

It is a FLIR SYSTEMS Thermovision A20

[nicoseris]

HELLO,

what is laptop ?

good reflow !

[1nicotinoff]

Cool!

[protonus]

What was the max temperature acheived?

Was the solder lead free?

[ppkerobotics]

Since today's laptops are made with RoHS compliant manufacturing

process we had to use higher temperature to melt the lead free solder,

therefore 220°C should be achieved to ensure that BGA balls are

melted. With soldering flame we could do this according to results can

be seen on this video.
