คำนิยาม
A Printed Circuit Board (พีซีบี) 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.
ข้อกำหนดการออกแบบ
Designing a 6Layers 1+N+1 Mobile Phone PCB entails adhering to stringent criteria:
- วัสดุ: S1000-2, chosen for its excellent thermal stability and mechanical strength.
- ความหนา: A finished thickness of 0.8mm ensures compatibility with slim device profiles.
- ความหนาของทองแดง: Varies between inner 0.5OZ and outer 1OZ to manage heat dissipation and current-carrying capacity.
- การรักษาพื้นผิว: Incorporates Immersion Gold and OSP (สารกันบูด) to enhance solderability and protect against corrosion.
หลักการทำงาน
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 (อีเอ็มไอ).
