Professional Product Overview: The 12-Layer High-Speed, High-Density PCB
In the era of high-speed data transmission and complex system integration, conventional printed circuit boards (PCB) fall short of meeting the performance demands of advanced electronics. El 12-layer high-speed, PCB de alta densidad is the engineered solution. Featuring up to 12 precisely aligned conductive layers, it enables intricate interconnections and efficient signal transmission within a compact footprint, serving as the “central nervous system” for high-end networking gear, data center servers, high-performance computing (HPC), and AI hardware.
As an expert fabricante de PCB y Proveedor de PCB, UGPCB leverages advanced processes to deliver reliable 12-capa placa PCB producción, ensuring your products maintain a competitive performance edge.
In-Depth Parameter Analysis: The Foundation of Performance
The capability of a high-quality multilayer printed circuit board is defined by its specifications. Below is an analysis of this product’s core parameters:
-
Recuento de capas & Stack-up: 12 capas. Este multilayer PCB design offers superior signal integrity (Y), integridad del poder (PI), and EMC performance compared to boards with fewer layers. It allows for dedicated power and ground planes, providing clear return paths for high-speed signals.
-
Grosor del tablero & Tolerancia: 2.4mm ±10%. This robust thickness offers excellent mechanical strength for backplanes and large-form-factor applications, ensuring reliability during mating and installation. The tight tolerance guarantees consistency in assembly.
-
Finished Copper Weight: Unique distribution:
1/1/1/1/1/2/2/1/1/1/1/1 oz. This indicates that the inner layers (L6 & L7) utilize 2oz heavy copper, designed specifically for high-current power delivery. The outer and other signal layers use 1oz copper, optimized for fine-line etching. This hybrid construction is a hallmark of alta fiabilidad fabricación de PCB. -
Critical Process Capabilities:
-
Minimum Drilled Hole Size: 0.2milímetros. Supports high-density BGA fan-out, enhancing routing flexibility.
-
Minimum Line Width/Space: 0.076milímetros / 0.09milímetros (3mil / 3.5mil). Logra Interconexión de alta densidad (IDH)-level routing, essential for high-speed signal propagation.
-
-
Acabado superficial: OSP (Organic Solderability Preservative). Compatible with both leaded and lead-free soldering, it protects copper pads from oxidation, offers excellent surface planarity, and is cost-effective—ideal for boards with dense SMT componentes.
Materiales núcleos & Key Technologies: Enabling Superior Signal Integrity
-
High-Performance Laminate: Utilizes Nanya NY6300S high-speed laminate. Its high glass transition temperature (tg >150°C) ensures dimensional stability and reliability during high-temperature reflow soldering. Its optimized dielectric constant (Dk) and dissipation factor (df) significantly reduce signal loss at high frequencies, forming the material foundation for PCB de alta frecuencia.
-
Advanced Copper Foil: Employs RTF (Reverse Treated Foil) cobre. Compared to standard electrodeposited (Edición) foil, RTF foil features a smoother, low-profile surface on the treated side. This reduces signal loss due to the “skin effect” at high frequencies, critically enhancing the performance of differential signals exceeding 10 GBPS.
-
Critical Process: Controlled-Depth Drilling (Perforación trasera): In 12-layer or higher multilayer PCBs, the unused portion (stub) of a through-hole via can cause significant signal reflection, degrading integrity. El back drilling process precisely removes this non-functional via stub, eliminating its negative impact—a key technology for high-speed multilayer PCB actuación.
