What is Micro Via PCB?
Micro Via PCB (Printed Circuit Board) is an advanced circuit board technology that achieves high performance and high functional density in small electronic devices through tiny apertures and high-density wiring. Compared with traditional printed circuit boards, Micro Via PCBs have smaller apertures and higher circuit density, making them more widely used in micro electronic devices. The design and manufacturing process of Micro Via PCB focuses on precision and finesse to meet the strict requirements of modern electronic products for volume, power consumption and performance.
The key to Micro Via PCB’s high-density wiring lies in its tiny aperture and precise manufacturing technology. Typically, the aperture of Micro Via PCB can reach tens of microns or even smaller, which is much smaller than the aperture of traditional printed circuit boards. This tiny aperture allows more lines to be routed per unit area, allowing for high-density circuit connections. In addition, the manufacturing process of Micro Via PCB uses advanced technology and equipment, such as laser drilling technology and chemical etching technology, to accurately create tiny holes on the PCB surface, ensuring the reliability and stability of high-density wiring.
Micro Via PCB also adopts a multi-layer stacking design, which enables the wiring and connection of complex circuits by introducing Micro Vias (microhole) connections between different layers. This design maximizes space savings and improves the overall performance of the circuit. In addition, Micro Via PCB usually uses high-performance substrate materials, such as polyimide (PI) or polytetrafluoroethylene (PTFE), which have excellent electrical properties and mechanical strength, further enhancing the reliability and stability of high-density wiring .
In short, Micro Via PCB achieves the goal of high-density wiring through tiny apertures and precise manufacturing technology. This advanced circuit board technology provides important support for the design and manufacturing of small electronic devices and promotes progress and innovation in the electronics industry.

To sum up, designing Micro Via PCB requires comprehensive consideration of multiple factors, including circuit density, microvia design, material selection, impedance control, thermal management, EMC, إلخ., to ensure that the final product meets performance and reliability requirements and can Successfully put into production.
What is the manufacturing process of Micro Via PCB?
When manufacturing Micro Via PCBs, they need to go through a series of precise steps to ensure the quality and performance of the final product. Following are the main steps in manufacturing Micro Via PCB:
Design verification: Before entering actual manufacturing, the accuracy and feasibility of the PCB design need to be verified first. This includes reviewing layout and routing to ensure all circuit connections are correct.
Raw material preparation: Select the appropriate substrate material, usually materials with excellent electrical properties and high temperature resistance, such as FR-4 or high-performance polymers. In addition, drilling machines and laser equipment for making micropores need to be prepared.
Layout and etching: Layout the design on the substrate and use photolithography to transfer the design pattern to a photosensitive etching layer. Unwanted metal is then removed via chemical etching or laser to create the desired lines and apertures.
Microvia Drilling: Use laser drilling or mechanical drilling techniques to create tiny apertures in PCBs. These microvias are key to achieving high-density wiring, so high-precision drilling equipment and technology are required.
Surface treatment: Treat the PCB surface to improve welding performance and corrosion resistance. Common surface treatment methods include tin spraying, gold spraying, silver spraying, etc.
Lamination and stacking: Different PCB layers are laminated according to design requirements to form a complete Micro Via PCB structure. This process requires strict control of temperature and pressure to ensure the quality and stability of the laminate.
Final inspection and testing: After lamination and stacking are completed, the final Micro Via PCB needs to be fully inspected and tested. This includes visual inspection, electrical testing, bore inspection, etc. to ensure the product meets specifications and standards.
The above steps show the main process of manufacturing Micro Via PCB. Each step requires a high degree of expertise and technology to ensure the quality and reliability of the final product.
How much does it cost to manufacture a Micro Via PCB?
The cost of manufacturing Micro Via PCBs involves multiple factors that directly affect the final manufacturing cost. Here are some of the main influencing factors:
Design complexity: The design complexity of Micro Via PCB is one of the key factors that determine the manufacturing cost. The wiring density, number of layers, number and location of micropores in the design will all affect the complexity of the production process. More complex designs usually require more processes and higher production costs.
Pore size: The size of the micropores in Micro Via PCB is one of the important factors in manufacturing cost. Smaller apertures typically require higher levels of equipment and technology to achieve, thus increasing manufacturing costs. In addition, the special requirements for micropores will also increase processing difficulty and cost.
Material selection: The materials used in Micro Via PCB will also have an impact on manufacturing costs. High-performance substrate materials such as polyimide (PI), polytetrafluoroethylene (PTFE), etc. are generally more expensive than ordinary FR-4 materials. In addition, the scarcity of supply of specialty materials and the complexity of processing technologies also affect costs.
Production scale: Production scale is one of the important factors affecting Micro Via PCB manufacturing costs. Large-scale production often reduces unit costs because fixed costs can be spread over more products. In contrast, unit costs for small-scale production will be higher because fixed costs need to be spread over fewer products.
Technical requirements: Micro Via PCB manufacturing involves high-precision processing technology and equipment, such as laser drilling, chemical etching, etc. These advanced technologies require high-end equipment and professional operators, thus increasing manufacturing costs.
To sum up, the manufacturing cost of Micro Via PCB is affected by many factors, including design complexity, aperture size, material selection, production scale and technical requirements. When choosing a PCB manufacturer, understanding these factors and rationally evaluating the cost structure will help reduce production costs and ensure product quality.
