Bga reballing on a budget

[Somerandomtechyboi]

Budget (including currency): cheap as possible (~15$ +-5$)

Country: indo

Games, programs or workloads that it will be used for: just basic stuff and alot of overclocking (if revived)

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): upgrading from a p5q to (if revived) an ep45 ud3p

 

If anyones been reading my build log thread you know my ep45 has a shot nb and it needs to be replaced, i have a dead p5q pro laying around and the nb seems to be good so im thinking of swapping the nb of the p5q pro into the ep45 ud3p and see if i can revive it

 

im looking into some very questionable methods on doing this cause budget so im thinking of converting an iron into a heat gun and making a diy stencil with a drill

 

I do have some scrap metal laying around so ill prob use those for stencil though is there a way to reball without stencil that isnt just manually placing a sht ton of balls on their pads?

 

Also how do i insulate stuff from heat? Cause i dont wanna break something else while doing my god awful attempt at bga rework, would kepton tape and/or art eraser work?

 

I do know i need a heat gun (ill diy this) some solder balls, some flux, tweezers, and something to use as a heat insulator, Anything else im missing?

Could be frustrating to drill that lot of precise holes for such so small holes.

Saw few balling videos they used this so.. I guess go for it?

I imagine this would be a lot more frustrating than the drilling itself. You could use solder paste maybe?

 

 

Probably you posted on the wrong sub-forum either tho.

Before transform iron into heat gun, maybe try to make it with halogen lamp and reflector

 

Also kapton tape is heat resistant not heat repellant

I think ive seen indonesian tutorials on using halogen lamps instead of heat guns, not exactly a replacement for heat guns cause how the hell am i gonna reball the chipset after i take it off with a bloody halogen lamp?

 

Would be pretty decent if i were looking to build a rework station cause its gonna be more precise than a heat gun but im just looking for the cheapest solution

 

Also ive found a "mini" heatgun for 3$ and its rated at 300w for some reason and says that its capable of reaching ~200c so that should be enough for melting solder and reflowing

Hmm that might work and be more convenient than manually placing a bunch of balls that look like they want to fall off and also not having to buy specific sizes but what temp do i need to reach for the solder paste to convert into solder?

Simply put the new reballed chipset back and let the lamp do the rest maybe? But for the sake of the hassle either, probably would be easier to just get a heat gun.

Never known heat-gun actually that cheap, even mine's kind of around $15-20 ish maybe (welp it's the quality product one). Link?

Tbh I don't even experienced in any re-ball soldering and just seeing those kind of videos. Probably others can help you better.

Actually im kinda having second thoughts now cause my cheap chinese mini dremel cant even cut through thin scrap metal, even cheap ass scissors work better xD

 

Ill look for other heat guns now

 

Edit : found one that looks to be abit higher power and alot less like a pos https://www.tokopedia.com/klikperkakas/nankai-hot-air-gun-heat-gun-pistol-pemanas?src=topads

Add 50k and you'd get something with decent quality (personally using their drilling machine and cordless screwdriver, fine as wine until now) and that 1 year warranty would be kind of useful in some cases.

Idk if i wanna spend an extra 90k over the heat gun ive picked, maybe if it breaks ill consider your reccomendation

 

I am spending quite abit more than usual on equipment but i can prob convince mom to buy for me since i have some broken boards and 4 seem to be fixable with this method, 2 p5kpl am se, 1 g31m es2c, and 1 p5qpl am

 

One of the p5kpl am se has a broken sb (human error by me cause the f ing thermal compound was hard as a rock), prob gonna be able to salvage a sb from another one of my mbs

 

Another has a broken socket with snapped pins so i can also salvage a socket from another mb, same with the p5qpl am

 

And the g31m es2c has a prob internally shorted sb so i can salvage an sb from one of my boards

 

 

The order of importance for me is g31m es2c - p5kpl am se - p5qpl am

 

Im more eager to fix the g31m es2c and 2 of the p5kpl am se boards and just salvage all my sht from my other mbs like my dead p5q pro, p5qpl am (trash fsb overclocking), and maybe even the gp41 board if any of the parts are even compatible (basically unrevivable and also trash fsb overclocking)

[Somerandomtechyboi]

Seems like im already spending near 20$ but i think itll be worth it when i can fix a crap ton more boards now, though i may upgrade the setup later and actually make a basic rework station with an extra heatgun below the mb that im gonna desolder

 

Currently i am looking to buy tweezers, universal stencil, heatgun, solder paste, flux, and a magnifying glass. Anything else that i might need?

To be fair, my house consisted of shit ton of equipment: the ol' expensive Bosch, Makita/Matkec, Tekiro/Ryu, Prohex, in the middle Black and Decker, even as the good-yet-inexpensive as Modern brands...

 

Depending on the use, yet the price-to-quality never lies. In a nutshell, the Bosch saw and drill, bought probably nearly a decade and half ago, still running fine until today. Got a legendary Maktec grinder and drill, for, like, half of decade and those things are actually the real deal as it used so much, daily, probably 5-8 hours a day, yet it just don't die. We got two Modern grinders... Welp, unusable for now as it needs repair on the motor and, you'd just get a new tool instead.

 

That's why I'd reconsider to get a kind of 'more expensive' equipment for the same function, they simply just last longer, hence reducing the 'belum dipake apa-apa udah rusak' runts, if you get what I mean.

 

Hell, I even bought a nearly $5 USB to USB-C charging cable, been close to 2 years and no problem/even deformation so far, compared to my old cable that I bought for... $2, yet the cable broke more faster than my relationship.

Dang, lots of mobo there. Good luck fixing those things tho. I would do the same thing over my recently-dead laptop as it's chipset died but... I don't think I would bother to even daily drive that anymore.

To be fair I spend nearly $200 for my final project and 40% of what I bought.... Basically, unusable. Not that kind of 'unusable', but it just sitting with no use so far, yet might be usable on the future.

Do you have a solder already? 60W one or more would be good. Don't bother with something below 60W as they can melt the solder too slow that it heat the components and it can break them up.

 

And seems like it, you already have the basic things to do it.

I only have a 40w but maybe ill just preheat it before using it

 

I think ill just buy the stuff that i need for desoldering furst before buying the other stuff like stencil, flux, and solder paste cause i need to know what the hell im dealing with before buying the other half of the stuff for reballing and resoldering cause i dont wanna waste money

Go for this then.

Would be good on something like phones/laptops/PCs or consumer electronics, but I wouldn't do it for something that being 'abused' so much after all of their life. If it's broken, welp, you know what's next.
