What is the manufacturing process of Micro Via PCB?

When manufacturing Micro Via PCBs, a series of precise and complex steps are required to ensure the quality and performance of the final product. Following are the main steps in manufacturing Micro Via PCB:

Before entering the manufacturing phase, the PCB design first needs to be verified. This includes ensuring that design documents comply with specifications and are free of potential errors or issues.

The first step in manufacturing Micro Via PCB is to prepare the substrate material. This may involve cutting the substrate to the appropriate size and ensuring the surface is clean for subsequent processing.

PCB design files are often converted into graphical layouts to accurately locate microvia locations and routing paths during the manufacturing process.

The design pattern is transferred to the substrate surface using photolithography technology. This usually involves coating a photosensitive resin on the surface of a substrate and then forming a pattern through an exposure and development process.

Next is the step of drilling holes in the PCB. Use laser drilling or mechanical drilling techniques to create tiny apertures in the substrate as per the design requirements.

After drilling is completed, the hole walls need to be metallized, usually using electroless copper plating or other metallization methods to ensure good electrical conductivity and reliable connectivity.

Next is a chemical etching process that removes unwanted metal and creates the desired lines and apertures. This step requires precise control to avoid over-corrosion or under-etching.

After chemical etching is completed, different PCB layers are laminated and stacked according to the design requirements to form a complete Micro Via PCB structure.

Finally, photolithography and pad processing are used to form the final circuit pattern and connection points. This step ensures Micro Via PCB connectivity and reliability.

The above steps show the main process of manufacturing Micro Via PCB. Each step requires sophisticated equipment and technology to ensure the quality of the final product meets requirements.

How much does it cost to manufacture a Micro Via PCB?

The cost of manufacturing Micro Via PCB depends on several key factors that affect the expenses throughout the production process. Here are some of the main factors:

Design complexity: The design complexity of Micro Via PCB directly affects the manufacturing cost. If the design requires features such as high-density wiring, multi-layer boards, complex signal and power separation, etc., then the manufacturing cost will usually be relatively high. This is because design complexity increases process and material costs during manufacturing.

Pore ​​size: The diameter of the micropores in Micro Via PCB has a great impact on manufacturing costs. Generally speaking, smaller apertures result in higher manufacturing costs because manufacturing tiny apertures requires more sophisticated processing equipment and higher production costs. Therefore, the manufacturing cost of Micro Via PCB increases as the size of the microvia decreases.

Material selection: The material of Micro Via PCB is also an important factor in manufacturing cost. High-performance substrate materials, such as polyimide (PI) or polytetrafluoroethylene (PTFE), will typically be more expensive than regular FR-4 materials. Additionally, manufacturing costs will increase if the design requires special materials or special surface treatments.

Production scale: The production scale also has a great impact on the cost of Micro Via PCB. Generally speaking, high-volume production enables lower unit costs because the fixed costs of production equipment can be spread over more products. Conversely, low-volume production typically results in higher unit costs because fixed costs need to be spread over fewer products.

Technical requirements: The manufacturing of Micro Via PCB requires advanced technology and equipment. If a manufacturer needs to invest in new manufacturing technology or equipment, those costs may be transferred to the final product cost. Therefore, the manufacturer’s technical level and equipment update rate will also affect the cost of Micro Via PCB.

To sum up, the manufacturing cost of Micro Via PCB is affected by multiple factors, including design complexity, aperture size, material selection, production scale and technical requirements. Understanding the impact of these factors on manufacturing costs can help manufacturers make more informed decisions when developing cost budgets and optimizing production processes.
