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.

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

Do NOT buy this if you value your sanity. It does not cure well. Even the smallest layer does not cure deeply and the result is liquid layers underneath. This is not high quality uv mask. You will regret buying it.

Excellent product

This solder mask does not cure nicely

Okay quality, the brushes feel a bit cheap and I wish this came with a metal needle tip along with the plastic ones it comes with. Overall a good value for the money for hobby cb trace repairs.

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

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.
