The Flexible Future of Electronics: Exploring Flexible Circuit Boards
Introduction
In the fast-paced world of electronics, innovation is the name of the game. As our devices become smaller, more powerful, and increasingly integrated into our daily lives, the demand for flexible and adaptable solutions has grown exponentially. One of the key enablers of this revolution is the flexible circuit board, also known as a flexible PCB board or flex circuit PCB. In this blog post, we will dive into the world of flexible circuit boards, exploring what they are, how they work, and their myriad applications across various industries.
Understanding Flexible Circuit Boards
A flexible circuit board, or flex circuit PCB, is a specialized type of printed circuit board that offers a unique advantage over traditional rigid PCBs – flexibility. While traditional PCBs are typically made from rigid materials like fiberglass or epoxy, flex PCBs are built using flexible materials such as polyimide (PI), polyester (PET), or even a combination of both. This flexibility allows them to be bent, folded, or contoured to fit the specific requirements of a given application.
How Do Flexible Circuit Boards Work?
The basic structure of a flexible circuit board is similar to that of a rigid PCB, consisting of conductive traces, pads, and components. However, the key difference lies in the substrate material. Instead of a rigid substrate, flex PCBs use a flexible material that can withstand repeated bending and flexing without compromising the integrity of the circuit.
Flex PCBs are typically manufactured using a combination of additive and subtractive processes. The process involves printing or etching the conductive traces onto the flexible substrate and then adding the necessary components. The result is a lightweight and compact circuit board that can be shaped to fit the available space.
Applications of Flexible Circuit Boards
Consumer Electronics: Flexible circuit boards are widely used in smartphones, tablets, and wearables. Their flexibility allows for unique form factors and more robust, durable designs.
Automotive Industry: In vehicles, flex PCBs are used in airbags, navigation systems, and instrument clusters. They can withstand the vibrations and temperature fluctuations common in automotive environments. Medical Devices: Flexible circuit boards are crucial in medical devices like pacemakers and medical imaging equipment. Their compact size and flexibility make them ideal for implantable and portable devices.

Exploring the World of Rigid-Flex Circuit Boards and Flex PCB Prototypes
Introduction
In the ever-evolving world of electronics, innovation is the name of the game. With a constant demand for smaller, more efficient, and versatile electronic devices, manufacturers are continually pushing the boundaries of what's possible. One significant development in this field is the use of flexible printed circuits (FPCs), rigid-flex PCBs, and the intricate process of flex PCB assembly. In this blog post, we will explore these cutting-edge technologies, their applications, and the rigid flex PCB manufacturer behind them.
Flexible Printed Circuits (FPCs)
Flexible printed circuits, often referred to as FPCs or flex circuits, are a vital component in modern electronic devices. They offer a flexible alternative to traditional rigid PCBs, making them ideal for applications where space and weight are at a premium. FPCs are constructed using flexible base materials, typically polyimide, and are designed to be thin and lightweight. Here are some key advantages of FPCs:
Space Efficiency: FPCs can be bent and folded to fit into tight spaces, making them invaluable in compact electronic designs.
Weight Reduction: Since FPCs are lightweight, they help reduce the overall weight of electronic devices, a critical consideration in industries like aerospace and automotive.

Why Choose Blind Via Flex PCBs
Many of today's flex PCB designs incorporate high-density components similar to those found in rigid PCB designs. This necessitates the use of blind and buried vias to route signal lines out from within these high-density components or areas of the design. One of the primary drivers for this is the 0.4mm pitch BGA package.
Blind Vias for Signal Routing Efficiency
Blind vias allow signals to be dropped down to the next layer from within the BGA SMT pad and then routed out from there. In high pin count devices, additional blind and/or buried vias may be required. Differences exist in how blind and buried vias can be implemented in a Flex PCB design due to the materials and manufacturing processes required.
Via-in-Pad Design for Enhanced Density
For flexible PCB designs with high layer counts utilizing high-density outer layers, the extra area used for separate pads and SMT components severely limits the available space for trace fan-out. By incorporating via-in-pad design in flex and rigid-flex PCBs, it is possible to significantly increase density by utilizing vias as mounting pads. Copper- or silver-filled flat vias allow for soldering components directly onto via holes.
Challenges and Considerations
Utilizing via-in-pad will release extra surface area for routing of traces. However, as with any new technology, there are several points to consider when using this construction type with flex. When manufacturers fill rigid PCB vias for SMT pads, they typically use a conductive epoxy, followed by copper plating and planarization. The final sanding leaves a very smooth pad surface, enabling normal processing of the circuit board through the pick-and-place cycle.
Improved Process for Flat Via-in-Pad
A new and improved process for a flat via-in-pad on multilayer flex PCBs is to fill the vias with a special type of copper plating. On thin flex layers that are laser-drilled, the new copper fill plating chemistry is designed to fill the laser via from the bottom up, creating a reasonably flat top on the via. Though some small dimpling can usually be seen, it presents no problem for assemblers. This plating technology is used on a wide range of flex and rigid-flex PCBs.
Conclusion
In conclusion, the use of blind vias and via-in-pad design in flex PCBs offers significant advantages in terms of signal routing efficiency and density. Despite the challenges associated with these technologies, advancements in manufacturing processes have made them increasingly viable for a wide range of applications. As the demand for high-density and high-performance PCBs continues to grow, the use of blind vias and via-in-pad design is expected to become even more prevalent in the future.

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.
