What Knowledge Do I Need To Have About the Stack-up of High Power Aluminum Base LED PCB?

Stack-up of High Power Aluminum Base LED PCB

 Stack-up of High Power Aluminum Base LED PCB

When we talk about the stack-up of the high-power aluminum base LED PCB, we put its layers into consideration. That is, what are the layers that make up this stack-up?

Circuit Layer Of Copper

At the topmost part of the stack or structure is the copper layer.

In this case, the manufacturer does not involve the regular FR4 material but uses the electrolytic copper foil.

The manufacturer uses the principle of etching with the copper material to form this layer of the PCB.

Usually, the thickness is within the range of 1oz – 5oz

Dielectric/Insulating Layer

This is the intermediate layer of the stack-up. Some call it dielectric layer, while others call it insulating layers. But in all, they are the same thing.

We call it the dielectric layer due to the purpose it serves.

Let’s check out what they are;

  • It serves as electrical isolation between the topmost layer (copper layer) and the bottom layer(aluminum layer).
  • It aids heat conduction
  • Enables temperature controls
  • It increases power load

Aluminum Layer

This is what we call the metal substrate. It is the base layer where other layers get attached.

For this kind of PCB, it is, therefore, the aluminum layer.

Usually, aluminum is best for high-power applications by virtue of its chemical, mechanical, electrical properties and cost.

What Are The Benefits Of A High Power Aluminum Base LED PCB?

The high-power aluminum base LED PCB isn’t a trending factor for no reason.

It offers great value to society; hence it arouses people’s interest.

There are several benefits of this object, and we will check ou what they are;

Durability

Printed circuit boards that emerge with metal cores display characteristic long life span.

This is one value aluminum adds to the PCB.

Due to the amazing characteristics of aluminum, it sustains and improves the life cycle of the PCB.

In addition, they are highly resistant to factors that cut short a PCB life’s span, such as wear and tear, temperature, and other environmental factors.

Very Cost-Effective

It is a fact that one major lookout people consider for a project is cost.

But unfortunately, things are not different with the PCB.

Every manufacturing process and transforming the PCB into a real deal costs money and resources.

However, the high-power aluminum base LED PCB is pretty cost-effective.

It is the cheapest amongst other metal core PCBs and very reliable.

Very Light in Weight

We are in a dispensation where people prefer lesser-weight things to their bulky counterparts.

Lightweight PCB gives the leverage of application in consumer products and more flexibility.

Since aluminum is a light element, it makes the PCB very light and easy to handle.

Perfect Distribution of Heat

Heat dissipation is a crucial phenomenon in electronic devices.

When there is an inefficient distribution of heat in the system, it cuts short the device’s life cycle.

Aluminum holds the reputation of being able to dissipate heat perfectly.

Produce Compact PCBs

The high-power aluminum base LED PCB makes it possible to produce lighting fixtures in small sizes.

This gives flexibility for a wider range of applications.

As a result, you can see its application in computers, mobile devices, etc.

Stability

Since we are dealing with a metal core PCB, it’s ideal to consider how it reacts to temperature.

Different metals react differently with temperature; some expand too much while others do so minimally.

Aluminum reacts well with temperature.

It demonstrates low expansivity amid high temperatures.

This means that the dimension and positioning of the components remain unchanged.

Other benefits include;

  • Reduction of thermal impedance
  • Improved power density
  • Lesser interconnections

What Are The Things To Consider When Selecting A High Power Aluminum Base LED PCB Manufacturer?

It is no news that there are several manufacturers in the PCB industry.

So, it is sometimes difficult to choose the manufacturer with the most effective production approach.

There are basic procedures to manufacture the high-power aluminum base LED PCB, but different manufacturers employ various tweaks to the system.

This accounts for the reason we have PCBs of different qualities.

However, crucial pointers can guide your decision for a manufacturer.

High power LED PCB

High power LED PCB

The Manufacturer’s Working Tools

Every kind of PCB has its corresponding tools that aid its production.

For example, the tools and equipment for manufacturing a non-metal core PCB with material like polyimide are different from the metal core counterparts.

The high-power aluminum base LED PCB is a metal core PCB and has its equipment.

So a factor you should consider is; whether the manufacturer has the necessary equipment for this PCB spec.

Credibility and Past Success

Every manufacturer should have a track record.

This could be the review of other customers the manufacturer has worked for.

Find out what the majority of people are saying about the manufacturer.

However, apply a measure of flexibility if it’s a new manufacturer in the industry.

Mode Of Operation

The way the manufacturer operates is a crucial factor to consider.

This will involve the point of making the order, then documentation and necessary processes, down to finishing the PCB.

An ideal manufacturer should have a good mode of operation that support industrial requirements and that of the customers.

Market Competitive Cost

Different manufacturers come with their respective costs.

This is quite tricky because people tend to fall into the hands of mediocre manufacturers as they seek low-cost services.

On the other hand, others misinterpret the high cost as quality service.

However, the ideal thing is to find a balance and watch out for a manufacturer with a reasonable competitive cost.

What Are The Judging Parameters Of A High Power Aluminum Base LED PCB?

Of course, we all want quality PCBs, and we all deserve the best.

But, unfortunately, not all high-power aluminum base PCBs you see out there are good enough.

So, several things justify the quality of the PCB.

And we will see what they are;

Thermal Dissipation

This involves the distribution of heat across the PCB.

How the PCB handles this phenomenon is very vital because an inefficient situation will damage the PCB.

So a PCB that can handle thermal dissipation efficiently can get the title” quality.”

Traces of the PCB

You can see these traces as a track, acting as a passage for the current across the PCB.

They help in conducting the signals on the PCB.

It’s best that the traces are in straight lines because when they tilt in angles, they result in adverse results.

This issue arises especially in the cases of high power traces.

But note that these factors can vary for PCBs with bending shapes.

Component Positions

This involves how the manufacturer places the components on the board.

You should note the following.

  • Placing inductors very closely isn’t the best practice. Inductors produce magnetic fields. Two or more conductors put close to each other will cause an interaction of the magnetic fields, which is not good for the PCB.
  • It’s not an ideal practice to place heat-generating components close to power resistors.
  • Components for high signal generation should be in a different section from those generating low signal.

Routing

This focuses on trace widths.

There are standards for the trace width given by the Institute for Printed Circuits (IPC).

The amount of current the trace will carry determines the width.

Therefore, it’s best to double-check with the standards of IPC.

The High Power Aluminum Base LED PCB Comprise What Materials?

Let’s look at it this way!!

Several core materials make up the PCB, and we can group them into metal core PCBs and non-metal core PCBs.

The non-metal core PCB has core materials like polyimide and FR-4, among a few.

On the other hand, the metal core PCB, which is the focus of this piece, comprises core materials like aluminum, copper, and iron.

Hence the aluminum base LED PCB is comprised of aluminum.

However, from the PCB structure, some other materials come to play.

Although the core material is aluminum, the PCB has other layers that comprise other materials.

  • The topmost layer, which comprises copper
  • The intermediate layer comprises dielectric materials that provide insulation to the system.

Why Does A High-Power Aluminum Base LED PCB Experience A High Current?

Some people observe that there are times when the current gets too high in the PCB.

So what could be the problem? Let’s find out.

On the first lookout, high internal resistance is one of the causes.

It all starts when the LED has been active for several hours.

This will result in the emission of heat from the internal chips.

Once the above continues to happen, the PCB temperature and internal resistance increase.

Another cause could be that the resistors on the PCB are already damaged.

Also, poor soldering is another trigger of this kind of situation.

And finally, it may be that there is a short circuit in the PCB.

What can you do?

You can take the following actions.

  • You can use a multimeter to investigate and detect if there is a short circuit in the PCB
  • Factor in the internal resistance of the PCB during the production phase
  • The PCB should have a guide on the maximum amount of current when using the LED lamps with the PCB. A resistor to limit the current is a good idea, and the current should not be above 20mili amperes.

Why Is Aluminum The Best Material For High Power LED PCB?

The PCB for high-power LEDs is usually that of metal cores, although some other sort of PCB can also prove effective for the LEDs.

Manufacturers can use several kinds of materials like copper and iron, but aluminum seems to be the first choice.

So, let’s find out why aluminum seems to be the best material.

Aluminum PCB

Aluminum PCB

Always Available

Availability of materials is key for any project.

No matter the cost or material quality, you can only work with what is available.

Aluminum is one of the abundant metals on earth.

As a result, manufacturers can get aluminum at any time, giving aluminum an edge in the race.

Very Cheap

Looking at other possible materials for the PCB, you will discover that aluminum is still the cheapest option.

Who wouldn’t opt for readily available material and even at a good price?

Since aluminum is cheap, when it is used for PCBs, it influences the price of the final products of application.

Manufacturers are happy, so also the consumers stay happy.

The Durable Nature of Aluminum

Checking the background, it is a famous fact that aluminum is a durable metal.

Aluminum is not brittle or fragile; it has high corrosion resistance.

So when manufacturers use it for PCBs, it prolongs the life span of the PCB.

Even as manufacturers handle the material during production, there is no fear of breakage.

The durable nature is every manufacturer’s dream.

Takes Care of Heat Distribution

The generation and distribution of heat is one major occurrence in PCBs.

So there exists a problem when products that require cooling or generate lots of heat uses PCBs with poor thermal dissipation.

Aluminum thrives perfectly in this situation. It has the ability to dissipate heat.

As a result, manufacturers embrace the aluminum base PCBs.

Lightweight

The progression of time has seen people’s choices shift from more bulky products to smaller and portable ones.

This results in the emergence of much reduced-sized PCBs to fit into smaller electronic devices.

In order to meet the demand, manufacturers seek PCB materials that will fit into small and less heavy product designs. Aluminum becomes the best fit in this case.

By nature, aluminum is a light metal, hence suitable for lightweight products.

Versatile Nature of Aluminum

On a basic basis, aluminum is very versatile; it is suitable for several applications, and PCBs are not an exception.

Moreover, due to its nature, it is compatible with a lot of electronic products.

Friendly With the Environment

People focus on how the environment affects the PCB and forget that the PCB can also affect the environment adversely.

New standards and regulations demand that electronic products be friendly with the environment and support recycling.

Aluminum fits these demands since it does not have an adverse effect on the environment.

Also, recycling aluminum is much easier.

What Are The Disadvantages of High Power Aluminum Base LED PCB?

Yes, the high-power aluminum base PC has numerous advantages.

However, it’s best to have balanced knowledge, knowing the few downsides of the high-power aluminum base LED PCB.

Several factors could constitute the disadvantages of the high-power aluminum base LED PCB.

It could be the production process, its usage, or the core materials.

However, there is no drawback with aluminum as a material for this PCB.

But the disadvantage is as a result of the manufacturing procedures.

Let’s check out what they are;

Double-Sided PCB

It isn’t easy to have the high-power aluminum base LED PCB as a double-layer PCB design.

However, digging into the industry, you will discover that this kind of PCB occurs as a single layer.

The double-sided PCB has two conductive layers, one at each side of the PCB.

Comparing it with the single layer PCB, it offers far more conductivity, hence its importance.

Unfortunately, having the high-power aluminum base LED PCB as a double-sided PCB is still an uphill task for manufacturers.

Electrical Pressure and Strength

When it comes to electrical pressure and strength, this kind of PCB isn’t the best.

Increased electrical pressure will take a toll on the PCB.

Reaction to Halogens

Aluminum base PCB thrives with several environmental elements or factors.

But it is doesn’t react well with halogens such as chlorine.

So, when there is the presence of halide ions, it tends to attack the PCB due to its core material, aluminum.

How Do I Evaluate The Performance Of High Power Aluminum Base LED PCB?

The term “quality” is action-driven. Therefore, from the action or performance of the PCB, you can adjudge the PCB as quality or not.

How do you evaluate the performance of this kind of PCB to know if it’s quality or not?

Well, you evaluate the PCB by seeing it in action. That is, observing its reaction and how it serves the product of application.

So to evaluate the performance of the PCB, analyze the following.

Expansivity

The PCB reaction to heat.

This involves its level of expansion.

When heat is generated, the components of the PCB tend to expand and contract, and this affects the placement of the components.

So a test to check this phenomenon will go a long way.

This is important because if the expansion is beyond minimal, it reduces the life of the PCB.

Timely Distribution of Heat

A lot of mechanisms come to play in the PCB. One aspect is the influence of temperature on the PCB.

When power gets into the printed circuit board, over time, it generates heat.

So the printed circuit board has to distribute the heat on time to prevent an increase in temperature of the components of the PCB.

The ability of the printed circuit board to distribute the heat effectively speaks a lot about its quality.

Inefficient distribution of heat will damage the printed circuit board.

Stability

This talks about the dimension of the components of the PCB.

On a general scale, every PCB design comes with its dimension.

An abrupt or significant change in the dimension after the completion of the PCB will put the components out of position.

A quick test on the PCB can help evaluate the dimensional stability of the high-power aluminum base LED PCB.

Since its metal core is aluminum, the dimensions should not change drastically due to influencing factors such as heat, etc.

Before we round off this section, it’s ideal to know that basic tests at the production phase help depict the PCB quality. Here are the tests.

  • Burn-in testing: this is a test to identify early failures in the PCB. It also targets the PCB load capacity.
  • In-circuit testing: this targets the solder connection of the PCB. The high-power aluminum base LED PCB will only thrive on quality soldering connection of components. Else, there will be an obstruction in conduction or the flow of current.
  • Automated Optical Inspection: this is more of a pictorial inspection of the PCB. The engineers use cameras to ensure the PCB correlates with the approved design schematics.
  • X-ray testing: this involves picking out defects not visible to the eyes. It targets the inner traces, solder connections, and barrels.
  • Time-domain test: this will use the time domain reflectometer to identify defects, usually in high-frequency PCBs.
  • Solder float test: this will check the amount of thermal stress each hole of the PCB can accommodate.

What Are The Challenges In Manufacturing High Power Aluminum Base LED PCB?

During the manufacturing process of the high-power aluminum base LED PCB, manufacturers experiences some challenges. Let’s see what they are;

Mechanical Manufacturing

The mechanical aspect of this PCB manufacturing process proves challenging.

This will include processes like v-scoring, drilling, and molding on the PCB.

They are pretty difficult with aluminum core PCBs.

However, experts say adjusting the drilling parameters of the PCB will help solve this difficulty.

Printing of Solder Mask

The thickness of the copper foil is the base for this problem.

When the copper trace is very thick, there will be a huge lapse between the board and trace surface.

As a result, printing the solder mask becomes a daunting task.

However, you can employ two-time solder mask printing to curb this problem.
