How to design organic substrate FC-BGA?

When designing an organic substrate FC-BGA, several key factors need to be considered to ensure good reliability and performance in the final design. These factors and corresponding design guidance are described in detail below.

First, designers should fully understand the functional requirements and performance specifications of the circuit. This includes having a clear understanding of the circuit’s operating frequency, signal integrity requirements, power consumption characteristics, etc. By in-depth understanding of circuit requirements, guidance can be provided for subsequent layout and routing.

Secondly, reasonable layout is one of the keys to ensuring the success of the design. In the layout stage, it is necessary to rationally arrange the positions of each functional module to minimize the length and complexity of the signal transmission path to reduce the possibility of signal interference and crosstalk. At the same time, ensure that the layout meets the signal integrity requirements of the circuit to avoid signal reflections and timing distortion.

During the routing phase, designers need to pay attention to maintaining good signal integrity. This includes using appropriate width wires, reducing wire bends and splits, and properly managing the distance between signal and power layers. By taking these measures, the transmission loss and delay of the signal can be reduced and the performance of the circuit can be improved.

In addition, designers need to consider factors such as thermal management and electromagnetic compatibility. In terms of thermal management, the heat dissipation structure needs to be properly designed to ensure that the circuit can maintain a stable temperature when working for a long time. In terms of electromagnetic compatibility, measures need to be taken to reduce electromagnetic radiation and sensitivity to ensure that circuits can work properly in complex electromagnetic environments.

Finally, designers also need to fully consider manufacturing feasibility and cost-effectiveness. During the design stage, you should try to choose common materials and processes and avoid using overly complex or expensive technologies. At the same time, attention should be paid to the maintainability and testability of the design so that subsequent production and maintenance work can proceed smoothly.

In summary, designing organic substrate FC-BGA requires comprehensive consideration of multiple factors such as circuit requirements, layout and routing, thermal management, electromagnetic compatibility, and manufacturing feasibility and cost-effectiveness. Through reasonable design processes and strict design specifications, we can ensure that the final design has good reliability and performance and meets the various requirements of the circuit.

What is the manufacturing process of organic substrate FC-BGA?

The manufacturing process of organic substrate FC-BGA is a complex and precise process involving multiple critical steps, each of which must be performed precisely to ensure the quality and reliability of the final product.

First, the manufacturing process begins with the preparation phase of the substrate material. At this stage, we select high-quality organic substrate materials, usually fiberglass-reinforced epoxy resin (FR-4), to ensure that the board has sufficient mechanical strength and heat resistance.

Next comes the laminating and laminating stage. At this stage, the layers of the multi-layer substrate are stacked according to the design requirements, and lamination equipment is used to firmly press them together to form an overall structure.

Inner layer circuit pattern generation is one of the key steps in the manufacturing process. At this stage, the circuit pattern of the inner layer is formed on the substrate through chemical processing according to the design file. The accuracy and precision of this step have a profound impact on subsequent processes.

The outer layer line pattern generation is similar to the inner layer, but on the outer layer, we usually use finer line widths and line spacing to meet higher density layout requirements. This requires highly precise photolithography and etching processes to achieve.

Mask pattern generation is used to define pads and component mounting areas. By coating a layer of solder resist on the surface of the board, and using photolithography and etching techniques to form a mask pattern, it protects areas that do not require soldering and provides accurate locations for soldering.

Drilling is done to create pass-through holes and mounting holes in the board. Precise positioning and drilling operations are performed through CNC drilling machines to ensure the accuracy and consistency of hole locations.

Electroplating is an important step in depositing copper onto via holes and trace patterns. Electroplating provides electrical connections and surface protection to protect copper from environmental oxidation and corrosion.

Etching is the process of removing unwanted copper layers from the board. Through chemical etching, only the circuit pattern and pad area are retained, and the excess copper is etched away to form the final circuit board structure.

Pad coating is used to protect the pad area and provide a solderable surface. This usually involves applying a layer of solder film or flux to the pad area to prevent oxidation and improve soldering reliability.

Finally comes the molding and final inspection stage. During the molding process, the boards are cut to the required dimensions and surface treated to remove possible dust and contamination. The final inspection phase includes visual inspection, dimensional measurements, electrical testing and reliability assessment of the board to ensure compliance with quality standards.

Throughout the manufacturing process, strict quality control and process monitoring are crucial to ensure that each step can be performed as required and ultimately produce high-quality organic substrate FC-BGA that meets design requirements.

How much does it cost to design an organic substrate FC-BGA?

Cost is an important consideration when considering designing FC-BGAs on organic substrates. The design cost depends on many factors, including substrate material, number of layers, line width/line spacing requirements, impedance control, pad shape, etc. Therefore, design costs can vary significantly from project to project.

First, substrate material is an important component of design cost. Generally, high-performance organic substrate materials are relatively expensive, while some common substrate materials such as fiberglass reinforced epoxy resin (FR-4) are relatively cheap. Additionally, design costs may increase further if the project requires the use of special materials or substrates of specific thicknesses.

Secondly, the number of layers will also directly affect the design cost. Compared with single-layer substrates, the manufacturing cost of multi-layer substrates will be higher. This is because multi-layer substrates require more production steps and more complex processes, which increases manufacturing costs.

In addition, design requirements such as line width/line spacing requirements, impedance control, and pad shape will also have an impact on cost. For example, smaller line width/line spacing requirements and tighter impedance control can increase production complexity and cost. Specially shaped pads may require additional processing steps, further increasing costs.

In terms of controlling design costs, we can take some effective measures. First, we can reduce costs by optimizing the design. Through rational layout and simplifying the design as much as possible, manufacturing complexity and material waste can be reduced, thereby reducing costs. Second, we can select the right suppliers and manufacturing processes to ensure optimal value without sacrificing quality. Adequate communication and consultation with suppliers can help us understand the key cost drivers in the production process and take appropriate measures to reduce costs.

Overall, designing the cost of organic substrate FC-BGA is a complex issue that takes multiple factors into consideration. Through reasonable design optimization and partner selection, we can effectively control design costs without sacrificing quality, thereby achieving successful project implementation.

Solder resist is usually made of photo-curing or thermo-curing resin, which has good heat resistance and chemical stability. They are often available in a variety of colors to differentiate between functional areas and provide surface flatness for easier assembly and soldering.

Solder Pad: The solder pad is a key component connecting the pins of electronic components and the PCB. They are gold-plated or tin-plated to improve soldering quality and reliability. Pads are typically applied to the PCB surface and connected to electronic components through soldering techniques during assembly. They must have sufficient surface tension and heat resistance to ensure a good solder connection.

Printing ink (Legend): Printing ink is used to print logos and marks on the PCB surface, such as component pin marks, circuit board version numbers, etc. They generally have good adhesion and abrasion resistance to maintain long-term visibility and readability.
