The
MECHANIC SU3 Black UV Fast Curing Solder Mask
is an epoxy-based, photo-reactive liquid designed for electronic circuit board repair. It is primarily used to restore or apply a protective insulating layer to a printed circuit board (PCB) that has been scratched, peeled, or damaged by corrosion.
Key features
UV curing: The mask is a photo-sensitive ink that cures and hardens quickly when exposed to ultraviolet (UV) light. The manufacturer states a quick 3-second curing time for the SU3 series, but a longer application of UV light or the use of hot air may be needed depending on the thickness of the application.
Insulation and protection: Once cured, it forms a durable, non-conductive, protective coating over the PCB traces. This insulates the circuits to prevent shorting, arcing, and damage from moisture and corrosion.
Soldering assist: It is effective for PCB repairs, including fixing damage on motherboards for phones and computers. For jumper wire repairs, it can be used to anchor the wire and insulate it from the surrounding components.
Color: The product is available in black, as well as other colors like green and transparent, to match the original board or provide contrast for specific repairs.
Applications:
BGA (Ball Grid Array) rework and repair.
Repairing damaged PCB traces.
Protecting components and circuits during soldering.
Preventing solder from flowing onto unintended areas.
How to use
Clean the area: Before applying the mask, thoroughly clean the repair area of any dust, dirt, or flux residue. Isopropanol is often used for this step.
Apply the mask: Use the supplied plunger and needle to apply a small, thin amount of the liquid solder mask over the area you wish to cover and protect. A tool like a toothpick or hobby knife can help spread it evenly.
Cure with UV light: Expose the applied area to a UV light source. Depending on the amount applied and the power of your light, this can take anywhere from a few seconds to a few minutes to fully harden. Some technicians use hot air from a rework station in conjunction with the UV light to speed up the curing process.
Check the cure: A properly cured mask will be hard and solid. If it remains tacky, it needs more UV exposure. Applying the mask in thin layers and curing each layer individually can produce a more robust result.
