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 (プリント基板) 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:
- 材料: S1000-2, chosen for its excellent thermal stability and mechanical strength.
- 厚さ: A finished thickness of 0.8mm ensures compatibility with slim device profiles.
- 銅の厚さ: Varies between inner 0.5OZ and outer 1OZ to manage heat dissipation and current-carrying capacity.
- 表面処理: 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).
