Absolutely excellent. I needed to mask over a 0.5mm BGA/LGA pad (Ublox MIA-M10C), and this worked perfectly - the consistency was just right for this repair work. The included brush was a little too big but I didn’t buy it for the brush. The cure also seemed reasonably fast but I didn’t time it - I put it under a UV lamp and it was solid when I came back to it.

The Ouwinway UV solder mask ink worked exactly as I hoped. It applies smoothly, is easy to work with, and provides excellent coverage for repairing damaged PCB traces and protecting exposed copper. The consistency is just right, making it easy to apply precisely where it's needed. After curing with a UV light, the solder mask hardened nicely and created a durable, professional-looking finish. It adheres well to the board and has held up great during soldering and rework. The two-pack offers excellent value, especially if you do electronics repairs regularly. Overall, this is a high-quality UV solder mask that performs very well, and I would definitely purchase it again. Highly recommended for anyone working on PCB repairs or electronics projects.

Good solder mask and quick cure under UV. Defenently preformed as expected.

Works well. Lots of extra tips and brushes for easy application.

Completely malfunction with UV lights, I tried 3 different strong UV lights, it takes for ever to dry, just top drying and when you puch it you'll see it didn't dry after 3 hours under uv light

This stuff works great. I was hesitant to buy it due to some of the reviews that it wouldn't cure thoroughly, but I'm a dentist and I also 3D print patient models and other things, so I have about a billion curing lights. My composite filling curing lights seemed to mostly cure it in a few seconds, but I put it in my resin 3D printer post curing unit for another ten minutes just to be safe, and it cured rock hard. I liked the consistency during application, it's thick enough that you can place it with intent, but it still flows well and naturally forms a smooth surface. So anyways, get a decent curing light or post-curing unit and your set

It works. Just don't use much. If you need a thicker layer do it in steps. Think 3D Resin printing. Takes forever for it to harden if its more then a thin layer. The tubes are a bit rough to use as they only take a small push for it to be flowing out way to fast. It works. I have used it. So it was worth the extra steps to use it.

Seems good but no way to pull extra resin out of syringe nozzle. Worked to harden on pcb but then the plunger just pulls out and doesn't creat suction to pull back the resin in the nozzle. You can either remove the nozzle with the extra resin in it and put it in the plastic bag with the other nozzle (which will then get uncured resin all over it), or you can leave the nozzle attached and it will slowly drip out of the tip. Oversight in the companies side. The plunger needs to be able to pull the body of the syringe back enough to pull the unused resin out of the nozzle to keep the nozzle clean. You will waste a lot of the resin or make a mess of what's left in the nozzle. You won't like this!

Es bueno, a mi me funciono, compre una lampara pequeña recargable aparte, si seca pero talves necesite una luz mas potente, pero quita de apuros

Tres satisfait merci

Works well but is a bit soft after curing. Still useful though.

Smothes poorly, doesn't dry very well even when using higher UV then requested, can be wiped off with rubbing alcohol meaning you can't clean any extra flux off the PCB.

Does not cure and when I hardens a bit on the top it breaks off in chunks and doesn't stick to the pcb board. 1 star at best.
