Understanding the 6Layers 1+N+1 Mobile Phone PCB

Product Overview

The 6Layers 1+N+1 Mobile Phone PCB represents an advanced electronic component tailored for integration into modern mobile devices. This PCB is characterized by its multi-layered structure, offering a balance between functionality and compactness essential for contemporary smartphones.

Definition

A Printed Circuit Board (Leiterplatte) is a foundational element in electronic devices, functioning as the platform that connects various electrical components. The term “6Layers 1+N+1” denotes a specific configuration within a PCB, indicating it consists of six layers, with the outermost layers dedicated to signal traces, power/ground planes, or a combination thereof, enhancing electrical performance and reducing signal interference.

Design Requirements

Designing a 6Layers 1+N+1 Mobile Phone PCB entails adhering to stringent criteria:

• Material: S1000-2, chosen for its excellent thermal stability and mechanical strength.
• Thickness: A finished thickness of 0.8mm ensures compatibility with slim device profiles.
• Kupferdicke: Varies between inner 0.5OZ and outer 1OZ to manage heat dissipation and current-carrying capacity.
• Oberflächenbehandlung: Incorporates Immersion Gold and OSP (Organic Solderability Preservative) to enhance solderability and protect against corrosion.

Working Principle

At its core, the PCB facilitates the flow of electrical signals between components. In a multi-layer design like the 6Layers 1+N+1, signal integrity is maintained through meticulous layer stacking, where ground planes can be interspersed between signal layers to minimize crosstalk and electromagnetic interference (EMI).

Applications & Classification

Primarily designed for mobile phones, these PCBs are also suitable for other portable electronic devices requiring high-density interconnect solutions. They are classified based on their layer count, material properties, and intended use cases, making them versatile yet specialized for mobile technology.
