On This Episode of The Art of Repair, Justin goes over the basics of a standard IC Reball in this first of 4 series on reballing. Taking you from Beginner to Master! This will allow you to save a ton of money on IC chips, and do more confident exploratory diagnostics among other cool things. Lookout for Reballing 102, where Justin goes more in-depth on some of the intricacies of each step as well as shows you a unique second method to do a quick reball for those who have mastered 101 on their own.

Pretty good just tried it with some memory ICs and it worked wonderfully with a poor stencil. A key is probably use some expired solder paste. Just reballed a 121 Ball BGA ... crazy it worked at the 3rd attempt. First time I obviously did it wrong, second time some paste issues - third time unbelievable everything looks good.

Clenaning iron before putting it to stand will significantly reduce tip lifespan. Rather leave it dirty and clean before next soldering or tin it before putting it to rest. It looks nicer, yep, but clean iron will expose metal alloy and it will oxidate quite fast. Great balls though, it is hands download best reball guide.

What do you recommend to do when the stencil lift itself up while pressing with the tweezers on the edge of the array?! Not all the time this is happening, however with larger ICs, that tends to happen often. Once that happens, the paste/balls will merge in the center where the stencil is lifted the most.

Hi, thanks for the video. It was very good tip, when you said to apply flux and 140C to lubricate the stencil. Now the balls didn't get stuck like they used to before using this tip. It took only 10 min to reball IC. (steps: Clean IC pads with wick, apply stencil, apply balls, heat 370C from corner angle, apply flux, heat to 140C, remove stencil, apply heat 370 to get balls self align.)

I don't have a problem with reballing. But I do have problem when the chip pads are oxidised and the balls don't like to hold to them. What's your advice on that? :)

@TheArtofRepair 7 ай бұрын

Normally I don’t recommend smaller tips but maybe a smaller J tip with some solder on it and the pad has some flux. It would also help if the entire chip was at a decent temp. So if you could use a ic jig to hold it you could heat it up with the hot air and see if that will break down the oxidation. I know the problem your having and it’s a common problem Remember flux is a detergent and a barrier so that plus the right amount of heat and solder should do the trick. Let me know how it goes!

Hey Teacher (I hope you don't mind me calling you that). I'm sorry but I've tried every single hint you shared in the video. By the way, thanks a lot for sharing. You rock! But unfortunately, there's ONE CHIP, or THE chip that literally just laughs at me every time I try something different: CYW4356XKUBG or BCM4356XKUBG, it's a Wi-fi/BT chip for the Nintendo Switch. I spread 63-37 solder with my soldering iron, remove the flux using a cloth. Then, I proceed to line my stencil (similar as yours) up with the chip, apply solder paste, hot air @350ºC with very low air speed. I struggle a little with indirect heat (even after following your steps), but eventually all the balls are formed, oh and all of that while still applying pressure around the chip with my stencil. And I end up with 2 or 3 bridges on the chip. I've also tried gluing the chip with the stencil using a tape behind the chip; Same result; I've tried leaving some flux on the chip because a friend of mine told me some balls might not be forming or staying on its spot because of the lack of flux; No, still same result. Although it was only one bridge, but it involved six or seven balls; I've tried changing the air temp to 365ºC and going up the air speed a little, but it rendered the ugliest result; Maybe something is wrong with my solder paste, which is a Mechanic one. 63-37, melts @183.. I dunno. I even tried changing from a steel spatula to a thermal paste spreader (I don't have a plastic spudger), but results didn't change. I'd love to watch you try your luck with it. Maybe it's just not meant to be reballed? Thanks again for the vid and I'm sorry I'm 2 years late for this. It took me a while to find your vid. Keep up the great work (:

It would remove any oxidation on the pads ensuring a good connection (if that was the cause of the fault). Downside is it takes time and there is a risk of removing pads. Mixing lead-free and leaded solder... Would lower the melting point and add lead to the alloy. I don't think it is a huge issue, especially if longevity isn't an issue. Would love to hear Justins opinion on this though

@TheArtofRepair 3 жыл бұрын

This will be answered in next Monday's pre video livestream in more depth, but in short, If we are realloying with 63/37 which is 183, then applying the same as paste nothing else should be effected. Cleaning the BGA array flat IC side is pointless in our microsoldering context. cleaning the bare board with wic. yes, always, but yal know how i feel about that haha.

@EgonSorensen 3 жыл бұрын

@@TheArtofRepair " If we are realloying with 63/37 which is 183, then applying the same as paste nothing else should be effected." Since RoHS directive, everything should be lead-free, including the BGA's (Imagine the horrors in production if only a few areas has to bee leaded and others lead-free) Lead-free is often SnAgCu alloys, so adding a bit of SnPb will 'only' add Pb to the alloy, though not in the normal 63/37 percent ratio. My view on this is: Know what you're dealing with, clean it up if in doubt - always do it correctly (even though it takes a bit of time - it will save you time in the long run)

Just to address the comment about solder balls being easier. I would say that if you’re just at the desk doing this. You can do the full paste reball of almost any size or density array in 2-3 minutes max. Fullsize balls will slow you down big time if you’re trying to get work done. Nobody has time for the reball to take 10-15 minutes alone when the full job needs to be 30 max.

@@Turnikov I would say I agree that Ingesting leaded solder paste is not a great idea like 10000% but let me throw this one out there. Safety is always number one and should come before any part of the soldering process. So for me. Washing your hands when your done soldering or wearing gloves during the process would negate that. To further that. One could use lead free solder paste. It just kind of kills the working range of hand soldering a bit. Now that might actually be ok if the hobbiest is just doing some rework on something rather large. And I would say it might be that if your doing something similar to that in my video that those working play ranges are pretty crucial to allow for a proper step soldering process to eliminate damaging other joints on the board on the other side of a pcb of that are currently underfilled.
