What is UV curable solder mask?

UV curable solder mask is a special type of resin that hardens when exposed to ultraviolet light. It comes different colors in a syringe type tube. You can find it online or purchase it from your local electronics hobby shop. There’s a few household items and supplies that can help assist the procedure.

How long does it take to cure UV solder mask?

Final Cure: Once all of the under exposed resin has been removed and PCB cleaned, it’s time to fully cure the resin. Using the UV light, expose the PCB again, this time for about 10 minutes. This will ensure all of the resin is hardened and fully cured.

What material is solder mask?

Solder Mask material is a fine layer of polymer. In terms of application, engineers will often use this material for copper traces in a circuit board, PCB. It is an essential material in circuit building projects, protecting the PCB from oxidization.

Is solder mask necessary?

Not always, but that depends on the design and end-use of the printed circuit board (PCB). Solder mask (also called resist and overcoat) is used to isolate conductive areas of the PCB by covering them with an insulative layer.

How do you cure a solder mask?

Once all of the under exposed resin has been removed and PCB cleaned, it’s time to fully cure the resin. Using the UV light, expose the PCB again, this time for about a minute. This will ensure all of the resin is hardened and fully cured.

Why is solder mask green?

But, why are printed circuit boards green? It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. The colour of the solder mask gives the board its appearance.

Is solder mask conformal coating?

(Don’t confuse solder mask with conformal coating. Conformal coating is also a protective coating but it’s applied to the assembled board rather than the unpopulated bare board.) Solder mask is usually green but many other colors are available.

What is the difference between solder mask and paste mask?

Solder mask is used for solder mask ink, while solder paste is used for paste. 4. Solder mask is applied as fabricating your circuit board, however, solder paste is used for SMT PCB assembly.

What is peelable solder mask?

A peelable soldermask is screen printed and used in order to protect selected solder holes against plugging during mass soldering. A peelable soldermask can also protect carbon elements and gold plated contacts during mass soldering.

What is the best UV solder mask for board repair?

Mechanics LY-UVH900 10ML Green UV Solder Mask used for board repairs. Solder mask insulates against electrical connections. Solder mask does not allow solder to stick to it. It is why you can solder to a solder pad, but not to the board itself.

What is the UV Index scale?

UV Index Scale. The UV Index scale used in the United States conforms with international guidelines for UVI reporting established by the World Health OrganizationExitLearn how to read the UV index Scale to help you avoid harmful exposure to UV radiation. No protection needed.

What is ly-uvh900 solder mask?

What is the function of a solder mask?

Solder mask does not allow solder to stick to it. It is why you can solder to a solder pad, but not to the board itself. It does not conduct electricity.
