2-Layer Rigid Printed Circuit Board

設計上の重要な考慮事項

Successful design of a double-sided PCB requires balancing electrical performance with manufacturability. 主な考慮事項は次のとおりです。:

Routing Strategy: Efficiently utilize both top and bottom layers for trace routing. Plated Through-Holes (PTHs or Vias) enable inter-layer connections. Careful planning of trace density is crucial to prevent signal integrity issues like crosstalk.
Hole & Pad Design: Specify appropriate drill sizes and pad diameters for all PCB vias and component leads to ensure mechanical strength and soldering reliability, 順守 IPC標準 for annular ring.
力 & Ground Planes: While dedicated planes are absent, designers should widen power and ground traces or implement a gridded copper pour to reduce impedance and enhance stability—a key aspect of robust プリント基板設計.
デザインルールチェック (DRC): Prior to fabrication, rigorously verify that all parameters (trace width/clearance, hole sizes) align with the manufacturer’s capabilities (as per this board’s specs) to guarantee PCB design for manufacturability (DFM).

作業原則 & 構造

The functionality of this double-layer circuit board stems from its layered structure:

工事: The core consists of an FR-4 insulating dielectric layer, clad with copper foil (通常 1 オンス) on both sides. The unwanted copper is etched away during PCB製造, forming the desired circuit traces.
Electrical Interconnection: Circuits on the two layers are connected vertically via Plated Through-Holes (pths), created through mechanical drilling に続く electroless and electrolytic copper deposition.
Surface Protection: The Lead-Free Hot Air Solder Leveling (出血) finish applied to exposed copper pads prevents oxidation and ensures excellent solderability for component assembly.
