Что такое Ultra-thin Multilayer PCB Процесс изготовления?

The fabrication process for ultra-thin multilayer PCBs involves several specialized steps to ensure the board’s thin profile and complex layer structure are achieved accurately. Here’s a detailed overview of the fabrication process:

1. Design and Layout: The process begins with detailed PCB design and layout, using CAD software to create the multilayer circuit design. This includes defining the number of layers, trace widths, интервал, and other design parameters suitable for ultra-thin profiles.
2. Material Selection: Choose appropriate substrate materials and dielectric layers with low dielectric constants and high thermal stability. Common materials include FR-4 for standard layers and specialized materials for high-frequency applications.
3. Photolithography: Apply a photoresist layer to the copper-clad substrate. The photoresist is then exposed to UV light through a photomask, which defines the circuit pattern. The exposed photoresist is developed, leaving a pattern that protects the underlying copper during etching.
4. Офорт: The exposed copper areas not covered by the photoresist are etched away using chemical solutions, leaving behind the desired copper circuitry. This process is repeated for each layer of the PCB.
5. Layer Lamination: The etched layers are stacked together with prepreg (pre-impregnated resin) layers in between. The stack is then laminated under heat and pressure to bond the layers together, forming a single multilayer structure. This step must be carefully controlled to maintain the thin profile.
6. Drilling and Vias: Drill holes through the laminated stack to create vias, which are essential for interconnecting different layers. For ultra-thin PCBs, microvias and laser-drilled vias are often used to minimize the impact on the board’s thickness.
7. Plating and Via Filling: The drilled vias are plated with copper to establish electrical connections between layers. For some designs, vias may be filled with conductive or insulating materials to ensure reliable electrical performance and mechanical stability.
8. Outer Layer Processing: The outer layers are processed similarly to the internal layers, including photolithography and etching to define the final circuitry. This includes the application of solder mask and silkscreen layers.
9. Инспекция и тестирование: Perform thorough inspection and testing to ensure the PCB meets design specifications and quality standards. Это включает в себя визуальный осмотр, Электрические испытания, and sometimes thermal and mechanical stress testing.
10. Finalization: The PCB is trimmed to its final shape, and additional features such as edge plating or component mounting holes are added. Final finishing processes, including surface coating and cleaning, are applied to prepare the PCB for assembly.

The fabrication of ultra-thin multilayer PCBs requires precision and expertise at each step to ensure the final product meets the required performance and reliability standards while maintaining its thin profile.
