AMTECH NC-599-V2-TF
This is what happened response from Amtech

 Customers have all reasons to be upset because of continued unashamed deceit - the V2 formula is materially different from ASM, certainly not an apple to apple comparison. What has been sold as AMTECH NC-559-V2-TF was in fact NC-559-ASM-TF. Inventec has been passing off NC-559-ASM-TF as V2 since 2018, simply labeling ASM as V2.

Timeline of the handcraft flux evolution

Circa 1995, at the beginning of era of electronics mass production, AMTECH developed NC-557 formula introducing famous pine scent for the first time, and it has been carried over the handcraft lineage ever since!

In 1997 the 1st generation no-clean NC-559-TF flux was developed, it retained the pine scent.

In 1998-1999 the 2nd 559 generation material emerged - a higher activity flux which addressed oxidation on old parts and hard to solder components - NC-559-AS-TF - had the same pine scent.

Subsequently, in 2003-2004 the third generation 559-series - NC-559-V2-TF - also retained the scent.

Pine scent has been a signature property for AMTECH handcraft fluxes for over the two decades!

NC-559-ASM appeared only in 2006 and it was a different kind of breed practically unseen before - universal odorless industrial no-clean formula for both Sn/Pb and SAC alloys and high-temperature. With right amount of tackiness, viscosity and activity for industrial applications and paste, but also with professional ultrasonic cleaning and responsible disposal in mind. The ASM had quickly became a choice for the assembly lines - a manufacturers' flux, (but also the most counterfeited flux of all times!).

NC-559-V2-TF, however, remained a direct replacement to AS, made for a human operator who hand-solders all day long for a living.

NC-559-ASM/V2/AS are not REACH compliant and that is the only thing the fluxes have in common, otherwise those are different formulas!

The pine scent remained and apparently is not going anywhere appearing also in the upcoming next generation AMTECH flux - NC-559-V3-TF!

The ousting of V2 (an HBr booster curse)
The V2 has been a great flux but also a challenge to make.There are a number of components, including Hydrobromic Acid which are not only difficult to source in modern times, but also posing danger in flux manufacturing. In addition, V2 may become sandy or crystallize, continues outgassing inside the syringe developing many tiny bubbles or small whitish lumps that may annoyingly keep clogging the tip. ASM, however, was more stable material, consistent from batch to batch, universal and UV-traceable. Inventec simply condemned V2 formula based on production challenges (but didn't stop cashing out on a good old V2 fame). As time went by we found out that Inventec has not been the manufacturer on many of the items, not just NC-559-V2-TF and VS-213-A-TF.

The turn around
We split ways with Inventec and reorganized into a holding with a brand new production facility operated by original AMTECH folks carrying genuine AMTECH DNA and able to innovate. We stabilized V2 production using less harmful booster acid, gave label fresh 3D look, added American flag to differ from Chinese and French lineage but also out of patriotism - AMTECH is one of those stellar products making USA proud world leader and we are on the mission to place the star spangled banner on every soldering bench worldwide!

The next big thing
NC-559-V3-TF - is intended to merge ASM/V2 forks in to a single 4th generation product suitable for handcraft and industrial use, BGA or paste. We've already seen RD5 revision - it is getting close to release! REACH compliant, universal, halogen-free, with UV-tracer - a marvel that one would expect a modern flux to be in the age on nano-tech and the most recent science.

Year 2022 is when 559 base turns 25 years old. A generation of techs grew up using AMTECH with pine scent - modern AMTECH Manufacturing production placed the sent back where it meant to be.

We would like to suggest the entire panel of AMTECH fluxes for your bench, although all fluxes would perform similarly well, we would give comments which application would be the best suitable for each particular flux.

Thank you for responding and making a video. We realize if you had this information before, the video would be even more informative. Perhaps you could revisit, compare different AMTECH fluxes - the possibilities are endless and historical facts may become useful.
