  • Rosin-based, low-activity, no-clean soldering tacky paste flux is designed for hand-soldering electronic repairs and rework using high-temperature alloys or a hot air station. It is suitable for prolonged exposure to heat. The flux maintains clarity and has a slow evaporation rate, requiring fewer top-ups and not turning dark.
  • VERSATILE APPLICATION: Designed for a wide range of soldering projects, this flux is perfect for electronics, electrical repairs, PCB assembly, solder paste, and more. It is used in semiconductors and multi-step assemblies. The best cleaning results are achieved on preheated PCBs, as it cleans most effectively while the PCB is still hot.
  • Excellent flow from the syringe - 30-50 x10'3 mPa/s. Halide-free (<0.05%). Surface insulation resistant. No copper mirror breakthrough. Low electrochemical migration (<1 decade drop).
  • ROL0 classification - non-corrosive, doesn't short components, can be left on board for multiple SMT assemblies (manufacturer recommends cleaning all flux residues at all times to avoid board contamination or voltage leakage on circuits with high impedance, also non-activated residue may potentially absorb moisture from air and subsequently cause corrosion). Clear residue can be easily removed by hot air, foam swab and basic solvents like isopropanol.
  • Industrial air-syringe intended for professional use with pneumatic dispensing machines, do not remove the piston stopper! Do not discard original nozzle cap, tighten the cap while not using the flux - flux may dry out upon extended contact with air. Use supplied dispensing tip and plunger to manually control the flow. Keep in a room temperature - do not refrigerate.


STIRRI hot temperature no-clean soldering paste flux used in semiconductors and multi-step assembly using high-temperature alloys. The solder flux paste ensures no copper mirror breakthrough and has a low electrochemical migration of less than 1 decade drop.
Solder Paste for Electronics – Efficiency and Practicality in One Product
This tacky flux is nearly odorless. Its translucent material ensures more visibility so you can easily reposition the pieces for more precision. The flux syringe is very easy to maneuver, allowing you to work with accuracy and avoid spills. The electronics soldering flux in amber syringe tube has an extended shelf life of up to 2 years.
Some features to keep in mind about our soldering flux paste:

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)

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.

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.

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

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.

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

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!

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.
