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.

Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too.

Types of layers for LED PCB Assembly

Normally, the base layer is made using aluminum alloy metal.

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

LED PCB specification

Quotation quantity

Once you have gathered these information, you can contact us and request for a quote.

Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be.

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.

After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors.

What are the main components and parts of LED displays

LED display, this light and shadow magician that is ubiquitous in modern cities, attracts our attention from large billboards on the street to live broadcast screens in stadiums with its dazzling colors and clear images. But what "parts" does it consist of? Today, let’s unveil the mystery of LED displays and take a look at the “heart”, “brain” and “skeleton” behind it.

Glowing "pixels": LED light beads and modules

When it comes to LED displays, the most core is of course the "LED" itself. These tiny LED light beads, like independent pixel dots, form what we often call "LED modules" through matrix arrangements integrated on the PCB (printed circuit board). Let you learn about the LED display soft module in 5 minutes.

LED light beads: Although it is small, it is the core of the glowing light. It is made of semiconductor materials and can emit three basic colors: red, green and blue (RGB) after power on. Through different combinations of these three colors and brightness adjustment, tens of millions of colors can be presented. The packaging technology, brightness, viewing angle and life of the lamp bead directly determine the display effect and stability of the display screen. Here is Mini LED vs COB packaging: a technical choice from the user's perspective.

LED module: Multiple LED lamp beads are arranged at a certain spacing, soldered onto the PCB board, and then controlled by the driver IC to form an LED module. You can think of it as LEGO blocks, and modules of different specifications can be spliced ​​into display units of various sizes. The flatness, consistency and protection level of the module (such as waterproof and dustproof) are crucial to the overall performance of the display.

Support and connection "skeleton": box

LED modules need a solid "home" to accommodate them, which is the "box". The box not only plays a supporting role, but also is responsible for fixing modules, power supply and heat dissipation.

Material: Common box materials include die-cast aluminum, sheet metal, carbon fiber, etc. Die-cast aluminum box is lightweight and has high precision, and is often used for rental screens; sheet metal box costs are relatively low and mostly used for fixed installation screens; carbon fiber box is popular in the high-end rental market for its ultra-light characteristics.

Structure: The box is designed with heat dissipation channels, power supply and signal interfaces. Good heat dissipation design can effectively extend the life of LED lamp beads and driver ICs. At the same time, the splicing accuracy of the box also directly affects the overall flatness of the display.

The "heart" of power supply: power supply

The light of the display screen cannot be separated from electrical energy, and the "power supply" is the one that provides stable and efficient electrical energy.

Type: LED displays usually use switching power supplies to convert mains into DC low voltage power required for LED lamp beads and drive ICs. Let you understand how LED light beads work.

Importance: The stability of the power supply, conversion efficiency, power factor and protection level (such as overvoltage and overcurrent protection) will affect the operating stability and life of the display. A good quality power supply can allow the display to work "healthily" for longer.

The "brain" of control and transmission: the control system

If the LED module is the "eye" of the display screen, then the control system is its "brain" and "nerve". It is responsible for receiving external signals and converting them into driving signals that the LED module can recognize, thereby realizing screen display.

Send card: Process the signals from the computer or video player and send them out via network cable or optical fiber.

Receive card (also known as driver card): installed inside the LED box, responsible for receiving signals from the transmission card and assigning them to each LED module. The number and performance of the received cards directly determine the refresh rate, grayscale level and screen display effect of the display.

Video processor: Displays that require complex processing such as playing high-definition video, multi-screen switching, and zooming, are usually equipped with professional video processors. It can uniformly process and optimize video signals in different formats to ensure smooth and clear pictures.

Control software: Professional software running on the computer, used to edit, manage playback content, set display parameters, etc.

The "blood vessel" that transmits signals: wire

What connects various components and transmits power and signals is a variety of wires.

Power cord: Responsible for power supply, and you need to choose a thickness that meets safety standards to ensure stable current transmission and no heating.

Signal line: transmits data signals, usually using network cables or optical fibers. High-quality signal lines can ensure the integrity and stability of signal transmission and avoid jittering, screen-flowing and other phenomena.

Fixed "support": steel structure

For large outdoor LED displays, a solid "steel structure" is also needed to support the weight of the entire screen and resist the invasion of natural forces such as wind and rain. The design and construction of steel structures require professional civil engineering knowledge to ensure the safety and stability of the display screen. Give you a steel frame LED screen: key features, case studies and buying tips.

Summarize

An LED display is the crystallization of the collaborative work of many precision components. From tiny LED lamp beads to huge steel structures, every link is crucial. Understanding these main components and their functions will not only help us better select and use LED displays, but also be clear about them in daily maintenance. The next time you see dazzling LED billboards on the streets, you may be able to see these "heroes behind the scenes"!

Thank you for watching. I hope we can solve your problems. Sostron is a professional LED display manufacturer. We provide all kinds of displays, display leasing and display solutions around the world. If you want to know: Full guide to renting indoor LED displays. Please click read.

Choosing the Right PCB Material: A Comprehensive Guide | PCB Power

Choosing the Right Printed Circuit Board Material: A Comprehensive Guide

The choice of materials commonly used for the fabrication of the PCB is extremely important in determining the quality of it. The selection of PCB base material can impact electrical properties, thermal and mechanical behaviour, and reliability of the final product. In this blog, we will learn about the printed circuit board materials which are available to the buyers and their characteristics.

Common Types of PCB Materials

A list of the most common printed circuit board material is given below:

1. FR-4

FR-4 is the most common substrate material for making multi-layer printed circuit boards. It is a fibreglass-epoxy composite, with high dielectric strength. The material FR-4 can retain its stability up to the temperature of 130°C (266°F). It is used in consumer electronics, industrial control, telecommunications and other general application gadgets.

2. Polyimide

Polyimide is famous for its heat resistance and flexibility characteristics. It is commonly applied to flexible PCBs, where the board can be bent or folded. For example, in the case of a smartphone design. Polyimide can work up to a temperature of 260°C (500 °F). It is appropriate for aerospace, automobile, and medical devices where high performance is required.

3. Metal Core PCBs

Metal core PCBs are designed with a metal base material, often aluminum or copper. It offers five times better heat dissipation than FR-4 boards. These boards are popular in areas of heat dissipation which may include LED lighting and power electronics. Metal core PCBs have better thermal management under thermal loads.

4. Rogers Materials

Rogers Corporation produces a range of high-frequency materials that are suitable for advanced applications requiring precise electrical performance. Rogers materials provide low-loss characteristics and stable dielectric constants across varying frequencies.

They are used in telecommunications, aerospace, and military applications.

5. Taconic TSM-DS TLY-5 & DS3

Taconic TSM-DS TLY-5 and DS3 are specialized PCB materials intended for high-frequency applications. They are characterized by low dielectric constants and loss tangents, which keep the signal integrity at RF and microwave frequencies. Taconic materials are used in telecommunications and automotive radar.

Factors to Consider While Choosing PCB Materials

These are some factors one must consider before selecting the material for a printed circuit board:

1. Material Type and Properties

The choice of PCB material significantly impacts its functionality and reliability. Understanding the properties of the materials, such as dielectric constant (Dk), loss tangent (Df), and thermal expansion coefficient (CTE), is important.

2. Thermal Management

If there is heat involved, then thermal performance is very important, especially for high-power applications. The main thermal properties to study are as follows.

Glass Transition Temperature (Tg): At this temperature, the material would go from being a rigid state to more flexible. Thus, higher Tg materials are better to be used at high temperatures.

Decomposition Temperature (Td): It is the temperature at which the material will begin decomposing. Better indications under very difficult conditions are seen in higher Td.

3. Manufacturing Process Compatibility

The chosen material should also correspond to the manufacturing method employed, i.e., through-hole or surface mount technology (SMT). For example, SMT relies on FR-4 for favourable drillability, while flexible PCBs need materials such as polyimide, which don't crack during bending.

4. Environmental Considerations

Always evaluate the PCB's operational condition since humidity, temperature rise and fall, and exposure to chemicals influence the selection process of materials. Ensure the selected materials can withstand these conditions without degrading.

5. Frequency Range

In an instance where high-frequency signals are involved, it is critical to select materials that have low dielectric loss. High-speed PCBs may require special material under this.

Conclusion

Choose the right printed circuit board material to get the best result in the electronic designs. Designers must know about the properties of various materials such as FR-4, polyimide, PTFE, metal core, and Rogers to satisfy the needs of the projects. Electrical behavior, thermal properties, mechanical strength, cost ,and feasibility of PCB fabrication during manufacturing will help you decide which material is most suitable for your particular project.

4.2. Arc Fault Detection Devices (AFDD)

AFDDs detect dangerous arc faults that traditional breakers miss, especially in aging wiring systems. Now mandated in some international electrical codes.

4.3. Integration with Energy Management Systems

Modern protection devices communicate with Building Management Systems (BMS) and Energy Management Systems (EMS) to optimize loads, reduce energy loss, and monitor system health.

4.4. Modular and Compact Designs

With space being a premium in panels, devices are now designed to be more modular, compact, and DIN-rail mountable without compromising performance.

5. Circuit Protection in Key Sectors

Industrial Sector

Protection devices are essential in high-load, high-risk environments. Motor control centers (MCCs), power distribution units (PDUs), and automation lines heavily rely on MCCBs, overload relays, and SPDs.

Data Centers

Uninterrupted power and quick fault isolation are mission-critical. Here, selective coordination using advanced circuit breakers ensures fault isolation without total shutdown.

Renewable Energy Systems

Solar PV and wind energy systems require specialized protection like DC fuses, DC MCBs, and SPDs to handle fluctuating currents and external conditions.

EV Charging Infrastructure

As EV adoption grows, protection against earth faults, surges, and over currents becomes vital. Type B RCDs and DC-rated breakers are commonly used.

6. Best Practices for Effective Circuit Protection

How Heat and Dust Are Silently Shortening the Life of Your Industrial LED Fixtures

Your lighting may look fine today—but hidden heat buildup could be killing it from the inside out.

Most industrial facility managers don’t realize their LED systems are being degraded by two common environmental enemies: heat and dust. On their own, they’re a nuisance. Together, they’re a long-term threat to your lighting investment.

The Problem with Dust and Heat

Dust buildup creates an insulating layer over the fixture, especially on heat sinks. This causes:

Reduced cooling efficiency

Overheating of LED drivers and components

Accelerated color shift and lumen loss

Shorter fixture lifespan—up to 42% less

And when combined with high ambient temperatures, the effects multiply.

📉 Case Example: In 2024, over 710,600 high bays were recalled due to overheating issues, many of them operating in hot, dusty warehouse settings.

Why LED Design Matters

To combat heat and dust, smart design choices make all the difference:

Metal core PCBs help transfer heat away from sensitive components.

Convection-cooled fixtures allow passive airflow to do the work—no fans required.

Remote driver setups keep sensitive electronics out of hot zones.

Smooth finishes and sealed optics help reduce dust accumulation.

What You Can Do

Conduct regular visual and thermal inspections

Clean fixtures in dusty areas to restore cooling performance

Use lighting solutions with proven thermal engineering

Don’t overspec brightness if cooling can’t support it

Conclusion

Heat and dust may be silent—but their impact is loud and costly. Recognizing how these forces degrade your lighting is the first step. The second? Choosing fixtures built to survive and thrive in tough conditions.

Application and Design Essentials of Fuse Holders in Modern Automotive Electronic Systems

I. Introduction

As automotive electronics and intelligence advance, vehicle electrical systems are evolving from traditional 12 V low-voltage networks toward 48 V mild-hybrid and higher-voltage architectures. As core circuit-protection and isolation components, fuse holders must not only handle high currents and short-circuit capacities but also withstand severe mechanical shocks, electromagnetic interference, and harsh environmental conditions. This article analyzes fuse-holder applications in automotive electronics from three perspectives—high-impact testing in 12 V/48 V systems, electromagnetic compatibility (EMC), and water-proof ratings (IP 67/IP 69K)—and, through case examples, explores key design considerations and related technologies.

II. Challenges in 12 V and 48 V Systems

System Voltage and Current Levels 12 V systems: Traditional ICE vehicles’ main power rail, powering ignition, lighting, sensors, and body-control modules. Typical fuse ratings range from 5 A to 80 A. 48 V mild-hybrid systems: Widely adopted in recent mild-hybrid vehicles to support high-power motor starts, regenerative braking, and electric-assist steering. Peak currents can reach 200–300 A.

Short-Circuit Arc and Melting Characteristics When short-circuit currents spike to thousands of amperes, the fuse must melt in milliseconds while suppressing arc energy to protect adjacent components and the plastic housing. In 48 V systems, integrated metal-alloy fuse elements and fuse-holder designs are critical to rapidly form a melt point in a low-impedance path and isolate the arc.

High-Temperature Environment and Thermal Management Under-hood temperatures can exceed +110 °C. In 48 V circuits, sustained high currents generate significant heat. Both structural and material choices must balance heat resistance and conductivity.

III. High-Impact and Vibration Testing

1. Standards and Test Requirements

ISO 16750-3 “Road vehicles – Environmental conditions and testing for electrical and electronic equipment – Part 3: Mechanical loads” Shock tests: Half-sine pulses (e.g., 100 g, 18 ms) and full-vehicle collision simulations (e.g., 30 g, 6 ms multiple pulses). Vibration tests: Random vibration (5 Hz–2 kHz, peak 10 g) and sine sweep (10 Hz–500 Hz).

USP 7637-2 Transient Electrical Pulse (Electrical Surge) Testing Simulates line short-circuit or load disconnection over-voltage pulses on fuse-holder contacts.

2. Design Considerations and Examples

Housing and Pin Retention Use threaded locks or clip-style metal inserts to prevent pin loosening under ±100 g shocks. Example: A premium ECU fuse holder uses an integrated φ2 mm stainless-steel insert molded into the plastic housing; after six-axis shock testing, contact resistance changes by <2 mΩ.

Spring Preload and Contact Stability Spring material: nickel-plated chromium stainless steel (CTE ≈13 ×10⁻⁶/K), validated via 500 h creep test at 150 °C. By tuning wire diameter and coil count, insertion/extraction force remains constant under vibration, maintaining contact-resistance stability within ±5%.

Base and Support Structures Add alignment posts and support pillars on the PCB or metal bracket to share shock loads and prevent the fuse holder from separating under impact. Example: A 48 V starter-motor fuse module passed 72 h of 3 g sine vibration (10 Hz–100 Hz) with no solder-joint failures or housing cracks.

IV. Electromagnetic Compatibility (EMC) Design

1. Main Interference Types

Radiated Emission: High dI/dt during fuse melting induces electromagnetic noise in nearby metal structures.

Conducted Emission: Short-circuit or melt pulses can inject noise back into the vehicle power distribution network.

Immunity: Must withstand ISO 11452 (antenna-injection) and ISO 7637 (surge/transient) requirements.

2. Design Strategies and Examples

Shielding and Grounding Metallize the fuse-holder housing or line a module interior with tin-plated copper foil to ensure a robust flange-to-ground connection. Example: A body-control-module fuse holder with an inner copper-plated shell achieves grounding resistance <5 mΩ, reducing radiated emission by 8 dB.

Filtering and Arc Suppression Integrate miniaturized LC filters or clamping diodes within the holder to tame short-circuit transients. In 48 V high-current holders, combine multilayer ceramic capacitors and large-value inductors to suppress differential and common-mode noise from 1 MHz to 30 MHz.

Material Selection Choose UL 94 V-0 plastics and low-dielectric-loss materials (e.g., LCP) to limit high-frequency coupling. Use high-temperature, flame-retardant plastics loaded with ferrite particles for EMI absorption and mechanical strength.

V. Water-Proofing and Dust-Proofing: IP 67/IP 69K

1. Rating Definitions

IP 67: Dust-tight; immersion up to 1 m for 30 min.

IP 69K: High-temperature, high-pressure spray (80 °C, 8–10 MPa), simulating under-hood cleaning procedures.

2. Structural and Sealing Designs

Silicone O-Ring and Gasket Grooves Design U-grooves at the cover–base interface to house high-temperature silicone O-rings (–40 °C to +200 °C rated). Example: An engine-compartment fuse holder with dual-O-ring U-grooves passed 100 cycles of 80 °C high-pressure water spray with zero ingress.

Overmolded, Monolithic Construction Overmold fuse terminals directly in plastic, eliminating assembly interfaces and extra seals. Materials: LCP with flame-retardant additives reduces joint count and boosts IP 69K reliability.

Self-Sealing Wire Connectors Use waterproof contact caps or integrated cone seals at the wire-harness interface to ensure end-to-end protection from the holder through the harness.

VI. Additional Features and Future Trends

Intelligent Monitoring Integrate Hall-effect current and temperature sensors with CAN/LIN interfaces to stream real-time melt events, overcurrent warnings, and historical logs to the vehicle network.

Modularity and Serviceability Develop 12 V/48 V hybrid modules allowing swift fuse-holder replacement without swapping entire distribution boxes.

New Materials and Miniaturization Graphene-enhanced composites and high-thermal-conductivity ceramics will enable higher current density and lighter fuse-holder designs.

Digital-Twin and Virtual Testing Leverage CFD/FEA thermal simulations and virtual vibration trials to cut design-iteration cycles to under two weeks.

VII. Conclusion

As the “first line of defense” in automotive electronic circuits, fuse holders in 12 V and 48 V systems must overcome high shocks, strong EMI, and harsh environmental demands. By combining:

Mechanical-structure optimization (locking features, preload springs, support pillars);

Comprehensive EMC measures (shielding, filtering, material absorption);

Robust water- and dust-proofing (O-rings, overmolding);

Smart and modular evolutions,

automakers can ensure reliable, serviceable, and upgradable protection for engine compartments, chassis controls, body electronics, and mild-hybrid power systems. Looking ahead, rising demands for power density and connected intelligence will drive further integration, material innovation, and digital design of fuse holders—cementing their role as the bedrock of automotive electronic reliability.
