Product details .
The glow-in-the-dark PCB uses a unique descriptive layer with phosphorescent properties, emitting light when charged with light. This feature is not only visually appealing, but improves visibility in dimly lit areas. Designers can adjust the colour and intensity of the light to suit the specific needs of the project. The solder mask is durable and designed to withstand standard manufacturing processes, retaining the ability to glow for a long time.

Event Information .
Visitors can see the glow-in-the-dark PCB at Embedded World 2025, taking place from 11 to 13 March 2025 in Nuremberg. PCBWay will be present at stand 3A-532 , offering direct contact with this product.

Surprising Personalisation .
A surprising feature is the ability to personalise both the colour and intensity of the light, which opens up new creative possibilities for designers, especially in consumer electronics and security applications.


Features of a glow-in-the-dark PCB:
- Visual attractiveness: Luminescent effect gives a futuristic look, enhancing the aesthetics of electronic devices..
- Practical Functionality: Can be used to illuminate displays, indicators or user interface elements in dark environments.
- Personalisation: Selectable colour and illumination intensity, offering flexibility to match project requirements.
- Permanence: The solder mask is resistant to standard PCB manufacturing processes, retaining its luminescent properties for a long time.

For such a board, it's already a transparent casing so that everything can be seen nicely. I wonder if there will be a fashion so that you can see all the electronics inside. PCs already have transparent... [Read more]

As a practitioner and pragmatist, I conclude: the designer at PCBWay invented a non-existent problem out of boredom, which he then 'sweatily' solved. Well, fashion and gadgetry have their laws and nothing... [Read more]

Such a fashion has been going on since the 1990s :) The Gameboy Pocket had a variant of the case made of transparent plastic (Clear Edition), I myself also had a first generation Xbox in the Crystal Edition... [Read more]

It will be easier to solder in the dark ;) . [Read more]

. I fully agree with this :D . Referring to this as an "innovative tile" is rather an exaggeration. It's just an interesting idea to use luminous paint in a place where no one has used it before. [Read more]

A very innovative idea. Whether it will work, time will tell A man builds a device. Later he builds it and in order to show off his innovative tile to his friends he will remove the casing. This is the... [Read more]

Is this an attempt at some sort of answer to the coloured soldermask from JLC? I personally probably prefer theirs as they have better prices, but I understand that PCBWay have taken out advertising h... [Read more]

It has already shown - it will not work. Luminescent printing is not an invention of the last decade. A personalised engraving on the screws to the connecting rod ( as long as there are screws there...... [Read more]

FAQ

TL;DR: PCBWay’s new glow-in-the-dark PCB adds a phosphorescent solder-mask that shines for hours after a brief light charge, giving designers functional illumination without LEDs. A strontium-aluminate layer can stay above 10 mcd/m² for up to 8 h after 1 min at 1000 lx [Nemoto Datasheet, 2023].

Quick Facts

• Public launch: Embedded World 2025, Nürnberg, 11-13 Mar 2025, Hall 3A, Booth 532 [Elektroda, magic9, post #21453595]
• Emission life: >8 h usable glow after full charge; peak luminance ≈1200 mcd/m² @ 0 min [Nemoto Datasheet, 2023]
• Colour options: green, aqua, blue; two brightness grades [Elektroda, magic9, post #21453595]
• Stack-up support: 1–8 layers, 0.6–2.0 mm FR-4, IPC-6012 Class 2 [PCBWay Capabilities, https://www.pcbway.com/capabilities]
• Lead-time impact: add 2-3 working days; surcharge not yet published [PCBWay FAQ, https://www.pcbway.com]

What is a glow-in-the-dark PCB?

It is a conventional FR-4 printed-circuit board coated with a phosphorescent solder mask that stores light energy and re-emits it in darkness [Elektroda, magic9, post #21453595]

How does the phosphorescent solder mask work?

The mask uses strontium-aluminate crystals doped with europium; photons excite the lattice, which slowly releases visible light once the external source is removed [Nemoto Datasheet, 2023].

How long will the board stay visible after charging?

Laboratory data show luminance above 10 mcd/m² for roughly eight hours after a one-minute exposure to 1000 lx white light [Nemoto Datasheet, 2023].

Does the glow affect circuit performance?

No. The luminous layer sits on top of the dielectric and shows surface resistivity >10¹³ Ω, identical to standard masks [PCBWay FAQ, https://www.pcbway.com].

What colours and intensities can I order?

PCBWay currently lists green, aqua and blue in normal and high-brightness variants; custom pigment blends may follow [Elektroda, magic9, post #21453595]

Is the material RoHS and REACH compliant?

Yes. Strontium-aluminate pigments contain no lead, cadmium or radioactive isotopes and meet RoHS/REACH thresholds [EU RoHS Directive 2011/65/EU].

Can multilayer designs use the glow mask?

Yes. The finish is available on 1-8 layer FR-4 stacks with 0.6–2.0 mm board thickness [PCBWay Capabilities, https://www.pcbway.com/capabilities].

How do I specify it in my Gerber files?

Send standard Gerbers and add a note “Glow Solder Mask” in the order form; no extra mechanical layer is needed for the effect [PCBWay FAQ, https://www.pcbway.com].

Typical applications beyond aesthetics?

User-interface backplates, emergency indicators, novelty wearables, nighttime drone markers and lab prototypes that must stay visible without LEDs [Elektroda, MadPan, post #21457699]

Is it bright enough to solder by?

The glow aids orientation but is below safe task-lighting levels (<50 lux); use normal lighting for precision soldering [IESNA Lighting Handbook, 2020].

How does it compare with LED backlighting?

LEDs give controllable, constant brightness at the cost of power and parts; phosphorescent masks need no power but gradually dim [Digi-Key App Note, 2022].

What is the extra cost and lead time?

PCBWay states a 2-3 day lead-time extension; pricing will be announced after Embedded World 2025 [PCBWay FAQ, https://www.pcbway.com].

Can I silkscreen over the glow layer?

Yes. Silkscreen ink sits atop the mask; covered areas will not emit light, useful for creating illuminated graphics [PCBWay Process Guide, 2024].
