Overview of packaging substrate process steps
Package substrate (패키지 기판) is a vital component of electronic equipment and plays a key role in electronic manufacturing. This key component not only provides support and connections for electronic components, but also ensures stable and reliable performance of the entire system through multi-layered processes.
The packaging substrate is a critical electronic component whose main function is to provide mechanical support, electrical connections, and heat dissipation. This assembly enables electronic systems to be designed compactly and work together by integrating chips, circuits and other key components onto a solid substrate. The design of the packaging substrate directly affects the performance and reliability of the entire device.
The following is an overview of the main steps in package substrate manufacturing:
Design and Layout: During the initial stages of package substrate manufacturing, a team of engineers is responsible for designing and laying out the entire substrate structure. This includes determining where components will be placed, how they will be connected, and overall routing.
Material preparation: Selecting and preparing materials is a critical step. The substrate typically uses high-performance insulating materials such as FR-4 to ensure stability and durability.
Patterned Fabrication: Fabrication of package substrates typically begins with the process of patterning the design. This involves transferring the design pattern to the surface of the substrate via photolithography.
Physical fabrication: Physical fabrication steps include processes such as etching, deposition and coating, through which complex multi-layer structures can be built on substrates.
High Temperature Processing: The packaging substrate is processed in a high temperature environment to ensure strong adhesion between layers and stability of the final product.
The synergy of these steps creates a precision packaging substrate that provides stable electrical performance and structural support for electronic devices. The innovation and continuous evolution of this manufacturing process is what drives the electronics industry forward and is also an important factor in ensuring equipment performance and reliability.

Patterned manufacturing is a key step in the packaging substrate process, which involves converting design drawings into actual manufacturable patterns. The main processes at this stage include photolithography, etching and printing. With photolithography, a light-sensitive material is used to create a design pattern; etching uses chemical processing to remove unwanted material to create a precise circuit pattern; and finally, printing adds the required metal layer to the substrate.
Physical manufacturing
Physical manufacturing includes a series of physical processes such as etching, deposition, drilling, 등. to further shape the structure of the packaging substrate. Etching is used to remove excess material, deposition involves adding thin layers of material to specific areas, and drilling is used to create vias. Together, these steps ensure substrate hierarchy and connectivity.
High temperature treatment
High temperature processing plays a vital role in packaging substrate manufacturing. This step is designed to improve material stability, enhance interlayer connections, and ensure the reliability of the entire substrate. During the high-temperature treatment, the substrate will undergo processes such as hot pressing and thermal aging to ensure its stability and durability during use.
Through these key manufacturing process steps, packaging substrates are precision manufactured, providing a reliable and high-performance foundation for modern electronics. Innovation and lean practices in these steps are critical to advancing the electronics industry.
Inspection and testing stage of packaging substrate process
In the manufacturing process of packaging substrates, the inspection and testing stage is crucial and is directly related to the quality and performance of the final product.
