My very first Rework flux by KINGBO Japan

[Kiriakos GR]

In the world of the ones who have master the job of rework/reflow/reballing, this product is considered as good enough, or better said as acceptable for high quality soldering.

Now its time to find out even by self how it measure up against common soldering cream, so to create my very own impression about it.

IPA it does dissolve it.
I guess that all that I need to evaluate is activation temperature and drying time.

All i can say is that you won't regret buying it. Yes, IPA dissolves it easily.

It's also good for cleaning nasty residue left by other fluxes, which IPA alone won't clean. Apply over nasty flux residue, heat, and then clean off with IPA.

Is not bad, but Amatech is must better.

Re: My very first Rework flux by KINGBO Japan

Whats IPA?

I have recently started using "brake and carb cleaner" to clean flux. Works great, its cheap and available at any auto parts store. Downsides are sometimes it takes a while to dry and if you burn it, you get phosgene gas, whch will kill you. Woohoo.

Btw, is this suitable only for bga type work, or also good for general purpose soldering?

Whats IPA?

Isopropyl alcohol

Re: My very first Rework flux by KINGBO Japan

Ahh. Must be good stuff because in my limited experience, IPA dissolves no flux I have found.

I use it for everything.

Fake Amtech is crap, and the genuine one is just too expensive for my taste. Kingbo is reasonably priced and does the job - so i'm sticking to it. Pun not intended.

Re: My very first Rework flux by KINGBO Japan

so i'm sticking to it.

Did you try to dissolve some of it with IPA so to make your own cocktail of liquid flux ?

Re: My very first Rework flux by KINGBO Japan

Got mine on order today. We shall see. Id be thrilled to not have to use brake cleaner.

Any trusted seller for Europe?

Re: My very first Rework flux by KINGBO Japan

My item came from eBay, one local professional friend of my ordered some quantity for him self and ordered one more just for me, and gave it to me as gift because we cooperate from time to time and we exchange favors by helping its other in a technical level.

Re: My very first Rework flux by KINGBO Japan

Got mine from ebay as well, no complaints. IIRC i got it from e-best trade.

Re: My very first Rework flux by KINGBO Japan

As for brake cleaner or carb cleaner, should read the labels. Some of the companies that sell their carb/brake cleaners in California, USA will reformulate to remove chlorinated organics. The ones that contain Methylene Chloride is the one to avoid as this is the chemical if burned will generate phosgene. Some of the brake/carb cleaners I bought do not contain Methylene Chloride and are safer.

Unfortunate Methylene Chloride is a great solvent and can remove a lot more crap than other organic solvents. Acetone is usually the replacement and it's nowhere as good as Methylene Chloride.

(Yeah, I buy this stuff for its intended use, I just so happen to use it for electronics just because I had it )

Re: My very first Rework flux by KINGBO Japan

eBay them. I asked because eBay is full of badly copied products.
Thank you.

Re: My very first Rework flux by KINGBO Japan

In this case I will offer two clues which possibly will help identifying authenticity.
a) inner plastic sealing cover
b) The cream color looks as to was butter.

Re: My very first Rework flux by KINGBO Japan

All this "kingbo" flux is too confusing for me.
Who is the "original" manufacter? Why cant i find the company website?
Is there a product datasheet?

Also,
why there isn't any reliable supplier that sells it?

.... maybe the original is not so original....

Somesort of industry which makes large scale OEM production, for industrial soldering systems.

Why cant i find the company website?

Because a company which work with large OEM customers usualy does not need fame from other sources.

Is there a product datasheet?

No one makes public his actual chemical composition, they are not stupid.

Also,
why there isn't any reliable supplier that sells it?

For some one accepting buying such a potentially hazardous product, which is for industrial use, you do make very lightweight questions.
This product is to be used by grownups professionals which are organized to handle the risk.
And if we are having this conversation today is because this product solution have been tested and it does the job.

Even car paint is dangerous when inhaled, but they are professionals out there painting all day long.

.... maybe the original is not so original....

I am not teaching today loyalty to trustful suppliers, the rule of thump is that if you discover a reliable one, you stick with him for ever.

Re: My very first Rework flux by KINGBO Japan

I´m not saying the product isn't good, it could be the best, i don't know, never used it.

The fact that it is oem produced doesnt explain the lack of the "brand" information.
What i look in a datasheet is not the product composition, but its specifications and properties. something like this

I would need to see a datasheet/specsheet/official website information to assume that.

Industrial or not, you don't find (very) strange there isn't a offical distribuitor for it? Not even an address or phone number in the label?

Re: My very first Rework flux by KINGBO Japan

It could very well be a fake, since it constains the same typo found on all Chinese fluxes, including the very common Amtech fakes: "State of Colifornia." However, if it is a fake, it's a really good one.
