UGPCB introduces its high-performance 18-PCB rigido a strati based on Megtron-7 materiale, engineered to meet the most demanding electrical and physical challenges, serving as the essential foundation for your next-generation advanced equipment.

1.18-Layer Megtron-7 Rigid PCB Panoramica del prodotto & Definizione

This product is an 18-layer rigid high-layer count PCB with a precisely controlled thickness of 1.86mm and overall dimensions of 165mm x 120mm. It utilizes industry-leading Megtron-7 high-speed low-loss laminate and features a 2-microinch (ca. 0.05µm) Oro per immersione in nichel chimico (Essere d'accordo) finitura superficiale. This specification represents an advanced tier in ad alte prestazioni Produzione di PCB, designed for applications where signal integrity, gestione termica, and reliability are paramount.

2. Considerazioni critiche sulla progettazione

Designing a successful 18-layer PCB, especially with high-speed materials like Megtron-7, requires careful attention to several core aspects:

1. Stack-up Design: A rational layer stack-up is critical for impedance control and crosstalk reduction. A typical 18-layer stack includes multiple signal, energia, and ground planes to ensure stable power distribution and clear signal return paths.

2. Controllo dell'impedenza: High-speed signal transmission demands precise controlled impedance PCB progetto. Trace width and spacing must be calculated accurately based on the Dk (Costante dielettrica) e Df (Fattore di dissipazione) of Megtron-7. We offer professional impedance calculation and simulation services.

3. Gestione termica: The 1.86mm board thickness and multi-layer structure necessitate effective thermal pathways in the design, such as using thermal vias to connect internal copper layers for efficient heat dissipation from components.

4. Interconnessione ad alta densità (ISU) Considerations: While this is a standard through-hole design, careful planning of via types (blind, buried, through-hole) is essential at this layer count to minimize stub effects and optimize signal paths.

3. Come funziona & Struttura

UN PCB multistrato functions like a highly integrated, three-dimensional “road network.” Electrical signals travel on copper traces (“roads”) on the surface and internal layers, with vertical connections between layers established through plated through-holes (“interchanges”). Dedicated power and ground planes provide stable voltage reference and noise shielding for the entire system. Questo 18-PCB rigido a strati is formed through a precise lamination process, bonding multiple core layers and prepreg sheets into a single, robust unit with excellent electrical properties. Its sophisticated PCB board structure is the foundation for implementing complex circuit functionalities.

4. Materiali core & Key Performance

• Materiali utilizzati:

  • Laminato: Megtron-7. This is a high-performance, low-loss copper-clad laminate from Panasonic, renowned for its stable dielectric constant (Dk ~3.3) and extremely low dissipation factor (Df ~0.001). It is optimized for applications above 10GHz and into millimeter-wave frequencies.

  • Lamina di rame: Utilizes Very Low Profile (VLP) or Reverse Treated Foil (RTF) to minimize “skin effect” losses caused by signal transmission on rough copper surfaces.

  • Finitura superficiale: Oro per immersione in nichel chimico (Essere d'accordo, 2u”). Provides a flat surface, excellent solderability, a reliable contact interface (suitable for gold fingers), and long shelf life.

• Outstanding Performance:

  • Integrità del segnale superiore (E): Exceptionally low signal loss ensures high-speed pulse waveforms remain undistorted.

  • Excellent Power Integrity (PI): Multiple dedicated power and ground planes offer very low power distribution network impedance and superior decoupling.

  • Alta affidabilità: The 1.86mm board thickness and premium materials deliver high mechanical strength, heat resistance, and long-term environmental stability.

  • Stable Impedance Control: Achieved through material consistency and precision manufacturing processes.
