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. Der Begriff “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.

Entwurfsanforderungen

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.
• Dicke: 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.

Arbeitsprinzip

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).
