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.

LED PCB Assembly specification

Number of layers for LED PCB

These layers are made up of aluminum and magnesium, but now have Copper base material and Ceramic base materials for LED PCB industry, we can meet it.

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.

These circuits are widely used in various industries where flexibility, high-density interconnects, and space optimization are crucial.

In this blog, we explore what multilayer flex circuits are, their advantages, applications, and why they are becoming increasingly popular in cutting-edge electronics design.

What Are Multilayer Flex Circuits? : MultilayerFlex Circuits

Multilayer flex circuits are flexible printed circuit boards (PCBs) that incorporate more than one layer of conductive traces to create a complex, high-density circuit. These circuits typically consist of multiple layers of flexible base materials, such as polyimide, which are bonded together with inner conductive layers like copper. The conductive traces on each layer are connected using vias (tiny holes that allow electrical connections between the layers), creating a compact and flexible circuit that can handle complex designs.

The key feature of multilayer flex circuits is that they offer multiple layers of electrical interconnections while maintaining the flexibility needed for applications where bending, folding, or compact form factors are essential.

Key Characteristics of Multilayer Flex Circuits : Multilayer Flex Circuits

Multiple Layers of Conductive MaterialMultilayer flex circuits can incorporate anywhere from two to several layers of conductive traces, each carefully designed to carry electrical signals or power. This multi-layer structure allows for high-density interconnections in a compact space.

The difference between copper base PCB, fake double-sided copper base PCB and true double-sided copper base PCB

Copper base PCB is the best heat dissipation and the most expensive circuit board among metal-based PCBs. Generally, copper base PCB include single-sided copper PCB, double-sided copper base PCB, and fake double-sided copper base PCB. The specific advantages of copper base PCB make them widely used in areas with large changes in high and low temperatures, as well as in the precision communication equipment and LED car light markets. The pad production processes of copper substrate manufacturers generally include immersion gold, OSP, HASL, immersion silver, etc.

Authenticity of true and false double-sided copper base PCB

Fake double-sided copper base PCB are generally designed by customers with two layers of circuits, but they are not connected to each other. The real double-sided copper base PCB is the double-sided circuit layer designed by the customer with vias connecting the two-sided circuits.

The copper base PCB, circuit layer requires a large current carrying capacity, so a thicker copper foil should be used, with a thickness of generally 35μm~280μm; the thermal conductive insulation layer is the core technology of the copper substrate. The core thermal conductive component is composed of aluminum oxide and silicon powder and a polymer filled with epoxy resin. It has a small thermal resistance (0.15), excellent viscoelastic properties, and is resistant to thermal aging and can withstand mechanical and thermal stress.

The copper substrate metal base is the supporting component of the copper substrate. It is required to have high thermal conductivity. It is generally a copper plate. Copper plates can also be used (copper plates can provide better thermal conductivity). It is suitable for conventional mechanical processing such as drilling, punching and cutting.

The structure of the real and fake double-sided copper substrate can be divided into 5 layers: 1 layer is the top copper foil, 2 layers are thermal conductive insulation materials, 3 layers are aluminum plates, 4 layers are bottom insulation materials, and 5 layers are bottom copper foil. Their functions are as follows:

The 1st layer of copper foil is used as the top circuit pattern (conductive).

The 2nd insulating layer is also the key layer to reflect the thermal conductivity, also known as the thermal conductive layer, which plays a dual role of thermal conductivity and insulation. Whether the heat generated by the LED lamp can be quickly transferred to the aluminum plate, it is necessary to know the thermal resistance of the thermal conductive insulating material.

The function of the 3rd layer is to transfer the heat conducted by the thermal conductive insulating material to the lamp cup again. There is also an installation function.

The functions of the 4th and 5th layers are the same as those of the 2nd and 1st layers above.

Through the above structure, we can easily understand the thermal conductivity and heat dissipation principle of the copper base PCB. In addition, the special process of copper base PCB processing and the thermoelectric separation production technology have improved the thermal conductivity of the copper base PCB by several times. Therefore, most designers who make LED copper base PCB now design a thermoelectric separation thermal conductivity method to make the heat dissipation performance of the copper base PCB better.

OKI Develops Printed Circuit Board Technology with Stepped Copper Coin Insertion to Achieve 55 Times Better Heat Dissipation in Outer Space. The OKI Group printed circuit board (PCB) business company OKI Circuit Technology (President: Masaya Suzuki; Headquarters: Tsuruoka City, Yamagata Prefecture; “OTC” hereinafter) has successfully developed multi-layer PCB technology with stepped copper coin insertion (“stepped copper coin” hereinafter) to achieve 55 times better heat dissipation compared to conventional PCB (*1). The stepped copper coin is offered in two types, circular and rectangular, to suit the shape of the electronic component mounted on the PCB. OTC is working to develop mass-production technologies with the aim of introducing PCBs incorporating this new technology into markets for compact devices or devices used in outer space or other environments where air cooling technology cannot be used. As semiconductors have become smaller and more sophisticated, countermeasures against the heat generated when processing large volumes of data at high speed have become an issue. In cases where device miniaturization prevents the installation of cooling fans or heat sinks or in vacuum environments such as outer space where air cooling technology cannot be used, PCBs are required to have heat dissipation structures with high heat conduction efficiency capable of transferring and dissipating the heat generated by PCB-mounted electronic components to the outside such as to a casing. In 2015, OTC developed proprietary design and mass production technologies for multi-layer PCBs based on copper coin insertion. This innovation embeds cylindrical copper coins with high thermal conductivity (*2) into PCB through-holes (*3) and bonds them to heat-generating electronic components to dissipate heat to the underside of the substrate. The use of copper coins that transfer heat to the underside of the PCB achieves high heat dissipation efficiency in cases where it is not possible to mount heat-dissipating devices directly to electronic components due to dimensional constraints of the device or where heat-dissipating devices cannot be mounted to certain functional surfaces (e.g., image sensors or light-emitting components). This time, OTC has made further progress with this technology and succeeded in developing the stepped copper coin that achieves approximately twice the heat dissipation efficiency (*4). The newly developed stepped copper coin features a larger heat-dissipating area relative to the bonding surface with the heat-generating electronic component to improve heat conduction efficiency. Additionally, aiming for an optimal heat dissipation structure to suit the shape of each electronic component, a rectangular type featuring a rectangular component installation surface and rectangular heat-dissipating surface has been developed, in addition to the conventional circular type, to increase the contact area and heat-dissipating area for rectangular electronic components to improve heat dissipation efficiency. Both types can be customized to obtain an optimal heat dissipation structure for the given shapes of the mounted component and the PCB itself and the substrate thickness. According to OTC President Masaya Suzuki, the stepped copper coin enables heat dissipation structures with high heat conduction efficiency to transfer and dissipate the heat generated by PCB-mounted electronic components to the outside such as to a casing in compact devices or in environments such as outer space where air cooling technology cannot be used. Having positioned the aerospace markets as a key focal point for its EMS business, OKI provides “space-quality” manufacturing services (EMS) ranging from the design and production of PCBs certified for all seven schedules of the JAXA (Japan Aerospace Exploration Agency) standards, cables, and other core components; simulations at the design stage; component screening and process diagnostics; to device reliability evaluations and failure analysis; PCB mounting (soldering and resin sealing); and unit assembly. OKI plans to continue advancing technology development and expanding sales for the global aerospace markets. Read the full article
