LED PCB Assembly

What is the LED Circuit Board assembly?

Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.

A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.

It is highly heat resistant and protects the PCB against heat and mechanical stress.

The circuit layer, which is covered by a copper foil which can range from one to ten ounces.

LED Board type- single or in panel

Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.

Some LED PCB Assembly is done on a single board while others are done on panel boards.

LED PCB Assembly Process

Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing. 

Below we show you the process.

Step1. Summarizing Project Information

Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly:

Gerber

BOM

Step2. Discussion and details about custom LED PCB Assembly

Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities.

For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want.

Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them.

Step3. Sample and feedback

After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc.

For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected.

The Bill of Materials is then generated from the information installed on the LED PCB.

All this information is used to assemble components which are identified from MOB to the LED PCB.

Copper-base PCB, Copper core PCB – Hitech Circuits Co., Limited

Aluminum PCBs are common insulated metal substrate PCBs (IMSPCB) widely used for LED lights, automotive lighting, and other high thermal conductivity applications. The thermal conductivity of aluminum PCBs is usually 1W/mK or 2W/mK. If an aluminum PCB's thermal conductivity can't satisfy your expected application requirements, why not consider copper-based PCBs?

Copper-base PCBs have better thermal conductivity than aluminum PCBs and provide you with much more design possibilities.

A copper base PCB is a metal core PCB with a copper substrate. If a hybrid PCB whose substrate is a copper plate inlay in the FR4 board, it is also a copper base PCB.

Usually, copper-base PCBs have the same structure as aluminum PCBs - single-layer, double-layer with single component-mounting side, double-layer with dual component-mounting sides, and four-layer with dual component-mounting sides. Even they use the same prepreg material to insulate the copper layers. However, the copper substrate (398W/mK) has better thermal conductivity than the aluminum substrate (237W/mK).

What's more, there's thermoelectric separation technology (also called direct touch technology) for copper-base PCBs. It means by solder mask opening and electroplating copper to increase the copper thickness of required positions, the heat conducts directly from the LEDs or other components to the copper base, while the circuit network is independent of the thermal network.

Metal Clad PCB: The Backbone of High-Power Electronics

n today’s rapidly evolving electronics landscape, the demand for more efficient, durable, and high-performing components has skyrocketed. One such innovation that has been pivotal in meeting these demands is the Metal Clad Printed Circuit Board (MCPCB). These specialized circuit boards are designed to manage heat dissipation, making them essential in applications requiring high-power or high-temperature performance, such as LED lighting, automotive electronics, and power converters. In this blog, we’ll explore what Metal Clad PCBs are, their advantages, and the industries where they are indispensable.

What is a Metal Clad PCB?

A Metal Clad PCB is a type of printed circuit board that incorporates a metal substrate (typically aluminum, copper, or a combination of both) in place of the conventional fiberglass base found in standard PCBs. The metal base serves as a heat sink, efficiently dispersing the heat generated by the electronic components mounted on the board.

MCPCBs are typically made up of three layers:

Metal Base Layer: This is the core material, often aluminum or copper, selected for its excellent heat conductivity.

Dielectric Layer: A thin, thermally conductive, yet electrically insulating layer that lies between the metal base and the copper circuitry. It allows heat to pass through to the metal core while keeping electrical signals isolated.

Copper Circuit Layer: The conductive layer that houses the circuit paths and connections for electronic components.

This structure allows MCPCBs to handle higher current loads and efficiently transfer heat away from sensitive components, extending their operational life and reliability.

Advantages of Metal Clad PCBs

Efficient Heat Dissipation: One of the primary reasons for using MCPCBs is their ability to dissipate heat much more efficiently than traditional PCBs. High-power components like LEDs or power transistors generate a lot of heat, which, if not properly managed, can lead to system failures. The metal base of the MCPCB acts as a heat sink, drawing heat away from these components and dispersing it effectively, ensuring that the system runs cooler and lasts longer.

Improved Durability: Metal Clad PCBs are more durable and resistant to wear and tear, especially in harsh environments where thermal cycling and mechanical stress are common. The metal core provides additional mechanical strength, making these boards suitable for rugged applications such as automotive electronics, industrial lighting, and aerospace systems.

Enhanced Performance: With efficient thermal management, the performance of electronic components on a Metal Clad PCB is optimized. Components can operate at higher current loads and temperatures without degrading, which is especially important for high-intensity LED lighting and power supply systems.

Cost-Effective Solution: While MCPCBs might have a higher initial cost compared to standard PCBs, their ability to extend the life and performance of electronic components results in long-term cost savings. For example, LED systems using MCPCBs last longer due to better heat management, reducing maintenance costs and replacements.

Compact and Lightweight Design: Despite the inclusion of a metal core, MCPCBs allow for a more compact and lightweight design. This is especially beneficial in applications where space is a premium, such as automotive and consumer electronics. The need for additional heat sinks and cooling systems is minimized, reducing the overall weight and size of the final product.

Applications of Metal Clad PCBs

Given their unique properties, MCPCBs are widely used in various industries, particularly where heat management and reliability are critical.

LED Lighting: The most common application for MCPCBs is in high-power LED lighting systems. LEDs generate significant heat, and without proper dissipation, their lifespan and brightness can be severely affected. Metal Clad PCBs ensure efficient heat transfer, enabling LEDs to run cooler and perform at their best.

Automotive Electronics: In automotive applications, where reliability and durability are essential, MCPCBs are used in headlamps, power converters, and motor controllers. The harsh operating environment of vehicles requires PCBs that can handle extreme temperatures and vibrations, making MCPCBs an ideal solution.

Power Supplies: MCPCBs are widely used in power supplies and power conversion systems. The metal core helps in managing the heat produced by high-power components, increasing the overall efficiency and reliability of the power supply.

Consumer Electronics: Devices like laptops, smartphones, and power banks that require efficient heat management also use MCPCBs to keep components running smoothly without the risk of overheating.

Conclusion

Metal Clad PCBs have revolutionized the way high-power electronics manage heat and deliver performance. Their unique structure allows them to provide efficient heat dissipation, durability, and enhanced performance across a wide range of applications. Whether it's in LED lighting, automotive electronics, or power supply systems, MCPCBs have become the backbone of industries that require reliable and efficient electronic components.

As technology continues to advance and demand for higher power and smaller form factors grows, Metal Clad PCBs will remain at the forefront of innovation, providing solutions that keep modern electronics running efficiently and effectively. For more details visit our website www.crimpcircuits.com

Printed Circuit Board (PCB): The Backbone of Modern Electronics

A Printed Circuit Board (PCB) is an essential component in nearly all electronic devices. These boards are designed to mechanically support and electrically connect various electronic components using conductive pathways. The significance of PCBs in today’s technological landscape cannot be overstated, as they form the foundation upon which most modern electronics are built. Whether it's a smartphone, computer, or even complex industrial equipment, the PCB plays a crucial role in their functionality.

Structure and Components of a PCB

At its core, a PCB is made up of a non-conductive substrate material, typically fiberglass or composite epoxy, with conductive copper traces embedded on it. These traces form electrical circuits that allow components such as resistors, capacitors, transistors, and integrated circuits to communicate and work together. The components are mounted onto the board through a process called soldering, where a metallic substance binds them to the copper pads, ensuring strong electrical connections.

There are several layers in a typical PCB:

1. Substrate Layer: The base material, often fiberglass, provides rigidity and insulation.

2. Copper Layer: A thin copper foil is laminated onto the substrate, forming the conductive pathways.

3. Solder Mask Layer: This is a protective layer that covers the copper traces, preventing short circuits and oxidation.

4. Silkscreen Layer: Used for printing labels and markings, this layer helps technicians and engineers identify components on the board.

PCBs can range from simple single-layer boards to more complex multi-layer boards. In advanced applications, multi-layer boards are used, where multiple copper layers are sandwiched together with insulating layers between them. This allows for higher component density and more complex circuitry in a compact form factor.

Types of Printed Circuit Boards

PCBs come in several different types based on the complexity of the design and the needs of the application:

1. Single-Sided PCB: The simplest form, with components and copper traces on one side of the substrate.

2. Double-Sided PCB: These boards have components and copper traces on both sides of the substrate, offering more flexibility for routing electrical connections.

3. Multi-Layer PCB: As the name suggests, these boards have multiple layers of copper traces, making them ideal for complex and high-performance applications.

4. Rigid PCB: These are made from solid, inflexible materials, commonly used in devices where the board must maintain a specific shape.

5. Flexible PCB: These boards are made from flexible materials and can bend, fold, or twist. They are often used in compact devices where space is limited.

6. Rigid-Flex PCB: A hybrid of rigid and flexible PCBs, these are used in complex devices that require both flexibility and stability in specific areas.

Manufacturing Process

The manufacturing of a PCB involves several precise steps to ensure quality and reliability:

1. Design: The process begins with creating a design using PCB design software. This includes defining the layout, trace routing, and component placement.

2. Printing the Design: Once the design is finalized, it is printed onto the copper-clad substrate using a photomask or a direct laser printing method.

3. Etching: Any excess copper is removed from the board, leaving only the desired copper traces.

4. Drilling and Plating: Holes are drilled where components will be placed, and conductive materials are plated inside these holes to establish connections between layers in multi-layer boards.

5. Solder Mask Application: A solder mask is applied to protect the copper traces and prevent short circuits.

6. Silkscreen Printing: Component labels and identification markers are printed onto the board.

7. Testing and Quality Control: The finished PCB undergoes rigorous testing to ensure there are no defects in the circuitry or connections.

Applications of PCBs

PCBs are found in a vast array of electronic devices and systems. Some of the key application areas include:

Consumer Electronics: Smartphones, tablets, computers, and home appliances rely heavily on PCBs for their operation.

Automotive Industry: Modern vehicles contain numerous electronic systems, from engine control units to infotainment systems, all powered by PCBs.

 Medical Devices: Precision medical equipment like diagnostic machines and wearable health devices depend on reliable PCBs for accurate functionality.

Telecommunications: Communication devices, including routers, switches, and mobile towers, are equipped with PCBs that handle data processing and signal transmission.

Aerospace and Defense: In high-stakes industries like aerospace and defense, robust PCBs are required for mission-critical systems, including avionics and radar equipment.

Future Trends in PCB Technology

As technology continues to evolve, so too does the development of PCBs. Advances in materials science, miniaturization, and automation are paving the way for even smaller and more powerful PCBs. Innovations such as flexible hybrid electronics (FHE), 3D-printed circuits, and high-speed PCB designs are expected to revolutionize industries by enabling more compact, lightweight, and efficient electronic devices.

Moreover, with the rise of the Internet of Things (IoT) and 5G technology, the demand for high-performance PCBs capable of handling greater data transmission speeds and power efficiency is surging.

Different materials. Ceramic substrate is an inorganic material, and the core is aluminum oxide or aluminum nitride; ordinary PCB board uses FR4 glass fiber board, which is an organic material. Ordinary PCB board can be laminated in multiple layers. LTCC is the mainstream of ceramic multilayer circuit board. The ceramic multilayer process currently being developed by Hitech Circuits Co., Ltd. is different from the traditional method. It uses magnetron sputtering technology to grow a layer of ceramic medium on the ceramic circuit board that has been metallized, and then re-metallizes this layer of medium to make the second layer of circuit.

b. The performance and application of ceramic substrates are different. The thermal conductivity of ceramic substrates far exceeds that of ordinary PCB boards. The thermal conductivity of alumina ceramics is ≧25W(m·K), and the thermal conductivity of aluminum nitride ceramics is ≧170W(m·K). They are used in industries with large heat dissipation requirements, such as high-power LED lighting, high-power modules, high-frequency communications, and track power supplies. The thermal expansion coefficient of ceramic substrates is more compatible with silicon wafers, and the product stability is higher. Ordinary PCB boards are widely used, mostly in private commercial products.

The difference between ceramic substrates and high-frequency boards

Different materials. Ceramic substrates are made of aluminum oxide or aluminum nitride, while high-frequency boards are mostly made of Rogers, Yalong, polytetrafluoroethylene, etc., with low dielectric constants and fast high-frequency communication speeds.

Different performance. Ceramic substrates are widely used in cooling sheets and systems, high-power modules, automotive electronics and other fields. High-frequency PCB boards are mainly used in high-frequency communications, aviation, high-end consumer electronics, etc.

3. In the field of high-frequency communications involving heat dissipation requirements, ceramic substrates are usually required to be combined with high-frequency PCB boards, such as high-frequency ceramic PCBs.

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.

Copper-base PCB, Copper core PCB – Hitech Circuits Co., Limited

Aluminum PCBs are common insulated metal substrate PCBs (IMSPCB) widely used for LED lights, automotive lighting, and other high thermal conductivity applications. The thermal conductivity of aluminum PCBs is usually 1W/mK or 2W/mK. If an aluminum PCB's thermal conductivity can't satisfy your expected application requirements, why not consider copper-based PCBs?

Copper-base PCBs have better thermal conductivity than aluminum PCBs and provide you with much more design possibilities.

A copper base PCB is a metal core PCB with a copper substrate. If a hybrid PCB whose substrate is a copper plate inlay in the FR4 board, it is also a copper base PCB.

Usually, copper-base PCBs have the same structure as aluminum PCBs - single-layer, double-layer with single component-mounting side, double-layer with dual component-mounting sides, and four-layer with dual component-mounting sides. Even they use the same prepreg material to insulate the copper layers. However, the copper substrate (398W/mK) has better thermal conductivity than the aluminum substrate (237W/mK).

What's more, there's thermoelectric separation technology (also called direct touch technology) for copper-base PCBs. It means by solder mask opening and electroplating copper to increase the copper thickness of required positions, the heat conducts directly from the LEDs or other components to the copper base, while the circuit network is independent of the thermal network.
