Flux in Europe

[Monkeh]

What about https://www.synergyelectronics.co.nz/datasheets/Multifix_450-01_EN.pdf
Does it also needs cleaning ? The manufacturer says no it does not.

>"How did you activate? I did the same test, without heating it is corrosive. After heating it is not corrosive. Test duration about 9 month (so far)."

I heated it with hot air.

>"So you're complaining that leaving a massive pile of it on copper attacks the copper? Welcome to flux. That's not what no-clean means."

The "no-clean" aspect means that leaving this in place will not damage the board. Other flux types can typically be very corrosive, and over time may etch through tracks leaving the board non-operational. No-clean is useful in prototyping as it removes the need for cleaning, although for aesthetic or "I don't want this sticky stuff on my board" purposes, you may still want to.

No-clean applies to activated flux. That giant unspread blob was not nearly fully activated.

I'm using this CW8500 tacky flux : https://www.reichelt.com/de/en/Flux-Solder-Paste/CHEM-CW-8500/3/index.html?ACTION=3&LA=446&ARTICLE=112697&GROUPID=4132&artnr=CHEM+CW+8500&SEARCH=flux&trstct=pos_2
It's from reichelt so it's home in a couple of days after purchase.

Works pretty well IMO.

Amount of flux for the price is a joke though.

Health hazards are even worse:

Hazard statements

H300Fatal if swallowed.
H319Causes serious eye irritation.
H350May cause cancer (see safety data scheet).

This just in: Chemicals capable of attacking metals are hazardous to your health. News at 10: Not breathing will kill you.

I've personally only used AG Termopasty TK83 no clean liquid flux and it works great for my needs.  May be worth trying out the gel fluxes from that Polish company, they're cheap enough to add to the "basket" besides one of those more expensive Amtech fluxes.

+1
one of my favorite (actually favorite one), better than the Chinese version of Amtech that has flooded the alibay.

Yes, true, but I don't use it that often so one tube/syringe lasts long enough.

Sorry, didn't find bio-flux.

Hi,
Last few syringes i have used from ALPHA OM-338, i really do like how this flux performs, leaves very little residue and cleans off really easy, but that smell and smoke is just a big no-no.
I remember FL-22 flux from Edsyn was good, but for that price Amtech 559 is a cheaper option if we look at volume/price.
Is there anything to recommend for BGA reworking other than these mentioned fluxes which should I try?

Another vote for edsyn fl22. Yes, bit on the expensive side, but really excellent stuff.

I realise its an old topic but it did come up while searching for difference between AS and V2 so it seems to be relevant still. I have been importing AMTECH flux from the USA into the EU and it is listed on Amazon.co.uk,.de,.es,.it,.fr and ebay so if you look for it my listing will likely come up as it is currently lowest price by a good bit. If there is interest I could do an EEVBlog discount and ship directly within the EU. Feel free to reply or PM.
