STIRRI-HT-TF no-clean high-temp soldering tacky paste flux (ROL0) - 10g syringe kit – for semiconductors, multi-step assembly, Hot Air repair/rework, prolonged exposure to heat

Finally a quality brand readily available to everyone without the confusion of clones/low quality flux that technicians have become so used to with online flux purchases.This is the real deal, from the original talent behind amtech. Stirri continues to innovate and brings unique formulas like this high temperature flux meant specifically for bigger boards and components that require lots of continuous heat (like HDMI port replacements on video game consoles)

The review written in another product with MT should be covered it but writing again,Price is very reasonable.Product is great with easy to clean, high temperature resistant that we were using the hot air station at 460C without burning.Packaging is great with all the nozzles and caps comes with plunger.Sold by the manufacturer means there is no counterfeit.

This stuff is great, and I'm excited to see it's being sold by the actual manufacturer -- be careful there are knockoffs out there.5 stars for a wonderful product, you're getting the real deal, no 0402 packages falling off when you flip your board! it sticks at 400 no problem!

This flux gets the job done and is convenient to work with if components are clean. The tackiness when cold is similar to axle grease, not too strong and sticky but enough to hold things in place a little. I wouldn't recommend this for repair work, since I found that components and boards need to be very clean. I was a bit sloppy with cleaning and left a little bit of conformal coating on a few through-hole components, and no quantity of this flux could get the solder to flow correctly. I wasn't using the best technique, but other fluxes seem to be more able to "cut through" contamination and oxidation. It works and it cleans up easily, but I was not impressed for the price.

Holds components in place while under hot air gun. The flux doesn’t float away once heated. The flux cleans up easily The syringe makes it convenient to apply the flux

At $10 for 5g, this is pretty expensive flux.. It's performance is average.

I am installing some fog lights on my Road King and did the connections last night. Everything went as expected, great clean, great flow. consistent. I am a real crappy tinner but I managed to make some nice clean connections with very controlled application of the paste. Five stars.

I've used a bunch of different flux brands and types, and this stuff is solid.Sticks around long enough to get a good joint, tacky to keep things from moving with air, and doesn't stink like crazy. It is a bit expensive, but you don't need to use a quarter tube per joint, so it lasts quite a bit of time, and just works the first time. Using cheap flux is just frustrating and the time savings alone is worth using this one.
