Repairing HP-Compaq CQ56 Laptop - No Video Signal - BGA Reballing

[@marceloQ7530]

Very good work, I hope in a while to finish my rework station, I want to be able to perform this task as part of my work. Cheers

Hi i hope to make a bga rework station homemade

[@j.lietka9406]

Hello did you complete it? Thanks

[@mypeeps1965]

How's it going Nik? You just made my Xmas top ten list!!!!

[@DominikMuhelye]

12:42 you ripped 4 pads in the top right corner. How does it still work? Yesterday I ripped just 1 pad and the laptop won't post, and its not even a reballed chip, but one that I bought form aliexpress..

[@NikTelio]

many pads on the bga are used for ground and if you rip one or two it will not matter, the pads you saw me ripping where not connected to a trace and they just detached from the pcb during the procedure.

[@DominikMuhelye]

@@NikTelio thanks for your answer, so my refurb chip was DOA.

[@GeorgeGeorge-xj2bc]

The cleaning of pads is easier while the bottom heater heats the pcb and the lead free solder melts easier with less danger to stuck the braid and lift some pcb pad.

[@moristo]

Good job friend, I want to see you make BGA picker made from "blackhead vacuum cleaner".

If reflowing wasn't a good long term solution why would reballing be any better. Are the leaded balls less prone to cracking?

[@j.lietka9406]

Reball it? Think it would be better to replace it! Is it me or is the fan kinda dirty?🤔 Also, does it help when the reball / replacement is done, to replace the corner sealant? Thanks & great work! The heat spreader, the small metal frame attached to the bottom of the board, it just comes out after lightly heating it?

[@NikTelio]

Replacing those kind of chips is a better solution but some of them seem to work for many years after reballing/reflow, the corner sealant (chip glue) does not need to be replaced, the small metal frame on the bottom of the board is not a heat spreader, it is a frame that holds the heat sink and yes it comes out if you heat it.

[@j.lietka9406]

@@NikTelio so removing the metal frame prior to pre-heat & reflow/reball ops is best. Thanks.

[@NikTelio]

@@j.lietka9406 you should remove it before you start the repairs

Fantastic video and your skill are verry good. I have a question. How to undersand if the problem Is in the solder chip o Is the chip broken ?

[@wyswietlaczeiinne76]

Witaj dobra robota:) Kiedy nastepne filmiki? Sam robiles stacje?

[@SUCRA]

I love this video and have watched it a couple of times, but I have one question, how did you know it was a problem with the chipset and not something else?

[@NikTelio]

Hi, when you see that the cooling system is clogged with dust and on the graphics chip is a dried out thermal pad, then you know that this chip overheated and got damaged.

[@SUCRA]

@@NikTelio I see, thank you.

[@DanielCardei]

awesome work! got a few questions: 1. Is ir6000 a waste of time? i want to modify it so i can do the job. 2. why you have those fans on the side? 3. the temp software? what make?

[@FrankMartin160]

Hi Nik.. in the past your advise helped me alot over reballing and stencil bending issue. Thanks.. i reballed an i7 cpu and when tried to solder to the board. The cpu popped like a popcorn at 220C.. preheat was 120 degree. Thus a broken cpu.. is there anything to put on the cpu when welding so the heat wont turn it into popcorn..??

[@NikTelio]

Hello, no bga chip gets popcorned when the temperatures are within normal range, unless it has absorbed moisture by laying around for a long time before you tried to solder it back to the board, if you reballed with leaded solder balls then the melting temp is 182c, no need to go to 220c, 205-210 is ok, and about preheating and soldering process, preheating the board before you start the soldering process is important, after preheating the bottom heater is the one that provides the most heat, the top heater only helps a little to rise the temp at the bga area to the desired point, if the bottom heater can not provide the most heat and the top heater is used to provide much heat to raise the temp then the chip will get too hot and will probably be popcorned (regardless of the low board temp reading). i have popcorned many chips until i finished the fine tuning of my bga rework station.

[@FrankMartin160]

@@NikTelio Thanks alot Nik.. i have done all gpu reballing with succes maybe because gpu chip pcb are thick enough, using same profile for intel cpu's past 6th gen, got 3 popcorns 2 went succes, What is the best bottom temps when doing intel chips.. ?? As per your advise about warton metals, i got it directly from warton metals.. thanks

[@Fabiuja]

Hi Nik! For reballing are you using lead or lead free balls?

[@NikTelio]

only balls with lead

[@BobBeatski71]

@@NikTelio Have you tried lead-free in the past ? If so, what did you observe ?

[@NikTelio]

When i get a new chip, it has leadfree balls on it and i solder it, other rhan that i do not use leadfree

[@jamzales]

So do you do repairs for people?. And by the way have been enjoying your content. Very well thought out station. Question. Normally are you driving heat from lower and upper ir heaters simultaneously?

[@NikTelio]

Hello, i preheat the bottom heater (800watt) up to 180c and then i start the reflow profile, and both heaters work together to heat the pcb up to ~240c, the bottom heater is the one that delivers the most heat, the top heater (about 150watt) just helps to rise the temperature on the bga area and reach at least 220c to melt the solder. i do not do repairs for people just for a few friends.

[@jamzales]

@@NikTelio Thanks. Nik. So do you have a link to the software?

[@NikTelio]

the software came with the PID controller and it works only with the same model PID controllers, if you need it i can upload it.

[@jamzales]

@@NikTelio Yeah do they still make that item? Didn't know the brand name of your pid you got. Did a raw search on ebay and scrolled through a few pages and didn't see the one you got. And thank you.

[@NikTelio]

Hi, no they stopped making this pid controller years ago but there are many other alternatives on ebay, newer models with more functions.

Hi Nik, I haven't seen your Video in a few months. May I ask if your soldering station can rework the integrated CPU 4th 5th 6 th ... ?

[@NikTelio]

Hello, unfortunately because of work i do not have much free time to make videos :( i think my station will need upgrades to be able to rework these chips

[@anilpatil7031]

Dear Sir, very Nice Jig developed by you. Good to see you made as an hobby project. Can you pls share Heater used details means size and rating.

[@NikTelio]

Hello, the top heater is 80*80mm 450w but it works at 39% power, it is connected to a power regulator to reduce the heat output, the bottom heater is 180*180mm 800w connected to a thermostat to make the panel reach and stay at a specific temperature. watch this video and in the description you will find a parts list: kzbin.info/www/bejne/r4DSc5eZpcuWa7c

white silicon paste not must be used in laptops, metalic paste is best for chipsets like gpu or cpu; if you put silicon the device must be overheated.

[@walterubogi]

Good work, is it working yet? How long it last? And how much you should be paid for a work like this? Thanks

Hi, i dont know, lets ask the owner of the laptop @R3DF3V3R

Is each stencil unique to each chip

[@NikTelio]

Hi, usually as the design of a chip changes the BGA and the stencil changes aswell but some same series chips use the same stencil.

I gott this exact same model from the Nvidia HP class action settlement, should have just kept my media center laptop with the borked wifi and the oven temp GPU. I see why they settled the suit with this laptop, it was just as bad if not worse than the system they got sued for.
