The first test for our WLED board codename "Sparkle Motion" 🌈💖💡 … 🐇⏳🌌

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED

We are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C. We'll also do an Arduino IDE board definition in case folks want to use it as a generic ESP32-to-LED-driver board. We're calling the board "Sparkle Motion" for now, but if you have other naming ideas, let us know - if we pick your name, you get a free board

Sign up, coming soon.

HEY I MADE SOME LED LIGHTS (Heads up: flashing bulb, loud fan)

[Video ID: On a wooden table sits some 194 sized bulbs. Some are glass, some are LED. There are a few PCB’s of unpopulated LED 194 bulbs. There is a stand in the middle holding one LED 194. Throughout the 12 second video, the bulb is turned on and off, with a single beep for each state change. There is also a LOUD buzzing sound, which is the universal power supply fan. End ID]

I have a few things in my world that use a 12 Volt 194 Incadesant light bulb. Two automotives, a Flashlight, and some old tech. And while the original factory-designed bulbs are alright, I would prefer to have something more modern and brighter. Now, there are a lot of LED replacements on the market, but none are perfect. Some need to be angled the correct way, some are polarized, some can only go in specific 194 sockets, and most are just absolute shit quality.

SO! I set out a design goal :) I wanted to make a 194 LED bulb that was A.) Rated for 14V 0.5A (improvement on the original), was not polarized, could fit into ANY 194 socket, had a wide viewing angle, Automotive grade, and lastly, could actually last longer than a week (Goal is at least 50K hours).

And this is my first attempt! It is . .. well buggy. What do you expect for prototype number 1? But, I have already designed a second one, and once I’m sold on how efficient this one is, I’ll finalize that second one and try again. But! despite the bugs, it does still light :) And it (somewhat) does meet all my requirements as well 💙💜

Anyways, I’ll add on an update for when part two comes out, maybe late Fall 2024. The boards are NOT cheap, as they need special requirements over a regular PCB.

What’s Aluminium LED PCB?

Aluminum LED PCB substrate is a metal - based copper-clad sheet with good heat dissipation. A single panel is generally composed of three layers of structure, namely the circuit layer (copper foil), insulation layer and metal base layer. It is commonly found in LED lighting products. There are two sides, the white side is used to weld the LED pins, and the other side is the natural color of aluminum, which is usually coated with heat-conducting gel and then in contact with the heat-conducting part. Among all metal core PCBS, Aluminum LED PCB is the most common type. The base material consists of an aluminum core and standard FR4. It features a thermal cladding that dissipates heat in an efficient manner while cooling components and improving the overall performance of the product. Currently, aluminum-backed PCBS are considered solutions for high power and tight tolerance applications.

2. Aluminum LED PCB with Copper Layer, Dielectric Layer & Aluminum Layer

Aluminum LED PCB has a similar layout to any other printed circuit boards with copper layer(s), solder mask layer(s) and silkscreen(s). Instead of having a fiberglass or plastic substrate, Aluminum LED PCB is made from metal core substrate, which consists of copper layer, dielectric layer and aluminum layer. This substrate is called as Aluminum based copper clad laminate (CCL). The glass reinforced and ceramic filled dielectric layer in-between copper layer and aluminum layer is very thin, but plays a very important role of electric insulation and thermal conductivity (because of minimum thermal resistance) from copper layer to aluminum base. The copper is etched into conductors and metal base is to withdraw thermal (/heat). The superior heat transfer capacity of Aluminum-based PCB helps cooling components while eliminating problems associated with managing fragile ceramics.

3. Thermal conductivity of Aluminium LED PCB

The general thermal conductivity of Aluminum LED PCB is 0.3, 0.6, 1.0, 1.5, 2.0, 3.0, 5.0, 122W/m.k, etc., among which 0.3-1.0w /m.k is the general conductive Aluminum LED PCB, 1.5W/m.k is the middle conductive Aluminum LED PCB, 2.0-3.0w /m.k is the high conductive Aluminum LED PCB. 5.0W/m.k is thin abasal substrate, and 122W/m.k is ultra-high conductivity Aluminum LED PCB, also known as ALC Aluminum LED PCB.

At present, the common Aluminum LED PCB on the market has a thermal conductivity of 1.0, 1.5, 2.0W/m.k high conductivity type Aluminium LED, wherein the thermal conductivity of 1.0W/m.k Aluminum LED PCB is called general Aluminum LED PCB, its insulation layer is composed of epoxy glass cloth bonded sheet; Aluminum LED PCB with thermal conductivity of 1.5W/m.k is called high heat dissipation Aluminum LED PCB, and its insulation layer is composed of epoxy resin or other resins with high thermal conductivity; The Aluminum LED PCB with a thermal conductivity of 2.0W/m.k is called the Aluminum LED PCB for high-frequency circuit, and the insulating layer is composed of polyolefin resin or Polyimide resin glass cloth bonded sheet. The thermal conductivity of Aluminum LED PCB varies according to the copper layer in the circuit. Different processes produce different levels of thermal conductivity.

We currently support Aluminum based CCLs from Ventec, GDM and BoYu with thermal conductivity from 1.0 ~ 7 W/m•K. The Aluminum LED PCB prices of Ventec is much higher than that with GDM and BOYU since material cost, and the prices of high thermal conductivity is higher than low thermal conductivity. Hitechpcb provides a wide range of electrical and thermally conductive interface pads, thermally conductive gap filler, thermal phase change materials and thermally conductive electrically insulating materials, as well as specialized equipment for high volume Aluminum LED PCB manufacturing. Choosing Hitech Circuits PCB as your Aluminum LED PCB supplier, just send your Gerber files and fabrication notes to us, we will deliver qualitied PCB boards to you on time.

4. Dielectric Constant of Aluminium LED PCB

The dielectric constant of Aluminum LED PCB substrate is a special detection method for Aluminum LED PCB. It is a variable Q value series resonance method through the measurement of dielectric constant and dielectric loss factor. The sample and tuning capacitor are connected in series to the high frequency circuit to measure the series circuit The principle of Q value.

The performance of Aluminum LED PCB includes requirements such as peel strength, surface resistivity, minimum breakdown voltage, dielectric constant, flammability and thermal resistance.

5. Classification of Aluminum LED PCB Substrate

Aluminum LED PCB-based copper clad plates are divided into three categories:

The first is the universal aluminum-based copper clad plate, the insulation layer is composed of epoxy glass cloth bonded sheet;

The second is the high heat dissipation aluminum-based copper-clad plate, the insulation layer is composed of high thermal conductivity epoxy resin or other resins;

Third, high frequency circuit aluminum base copper plate, insulation layer by polyolefin resin or Polyimide resin glass cloth bonded sheet.

The biggest difference between aluminum clad copper plate and conventional FR-4 clad copper plate is heat dissipation. Compared with 1.5mm thickness of FR-4 clad copper plate and aluminum clad copper plate, the former thermal resistance of 20 ~ 22 ℃, the latter thermal resistance of 1.0 ~ 2.0℃, the latter is much smaller.

6. Aluminum LED PCB Performance:

(1) Heat dissipation

Many double panel, multi - layer plate high density, power, heat distribution is difficult. Conventional printed board substrates such as FR4, CEM3 are bad conductors of heat, insulation between layers, heat does not escape. Local heating of electronic equipment is not excluded, leading to high temperature failure of electronic components, and Aluminum LED PCB can solve this problem of heat dissipation.

(2) Thermal Expansibility

Thermal expansion and cold contraction is the common nature of substances, and the coefficient of thermal expansion of different substances is different. Aluminum based printed board can effectively solve the problem of heat dissipation, so that the printed board components of different substances on the thermal expansion and contraction problem, improve the durability and reliability of the whole machine and electronic equipment. Especially solve SMT (surface mount technology) thermal expansion and shrinkage problems.

(3) Dimensional stability

Aluminum-based printed boards are obviously much more stable in size than those made of insulating materials. Aluminum base printed board, aluminum sandwich board, heating from 30℃ to 140~150℃, the size change is 2.5~3.0%.

(4) Other reasons

Aluminum based printed board, with shielding effect; Instead of brittle ceramic substrate; Safe use of surface mounting technology; Reducing the real effective area of the printed board; Instead of radiator and other components, improve the heat resistance and physical properties of products; Reduce production costs and labor.

7. Why choose Aluminum LED PCB from Hitechpcb? What are the advantages of Aluminum LED PCB?

(1) Good heat dissipation performance: Aluminum LED PCB can reduce the thermal resistance to the minimum, has a smaller thermal resistance, thermal expansion coefficient is closer to copper foil, so that Aluminum LED PCB has excellent thermal conductivity and heat dissipation performance, reduce the module operating temperature, prolong the service life.

High current load: Using the same thickness, the same line width, Aluminum LED PCB substrate can carry higher current.

(2) Good machinability: can replace ceramic substrate, better mechanical endurance. At the same time, high strength and toughness, can realize large area printed board manufacturing and component mounting.

(3) Good electromagnetic shielding: In order to ensure the performance of electronic circuits, some components of electronic products need to prevent electromagnetic radiation and interference. Aluminum LED PCB can act as a shield plate, play the role of shielding electromagnetic wave

(4) Environmental protection: The Aluminum LED PCB used in the raw material is non-toxic and can be recycled. Meet RoHs requirements.

(5)Light weight: Aluminum LED PCB has a surprisingly light weight with excellent strength and elasticity, which is very convenient.
