🏗 概要 / Overview

PCB検証 (Validation) は、設計された基板が 性能・信頼性・製造性 の全ての要求を満たすことを確認する工程です。
PCB validation ensures that the designed board meets requirements for performance, reliability, and manufacturability.

対象は 信号品質 (SI)、電源安定性 (PI)、熱特性、EMC適合性、製造性 (DFM) に及びます。
Targets include signal integrity (SI), power integrity (PI), thermal characteristics, EMC compliance, and manufacturability (DFM).


🔑 検証カテゴリ / Validation Categories

📡 SI (Signal Integrity)

Reflection, skew, jitter analysis.
Evaluation of via stubs.
Eye diagram and TDR simulations.


🔋 PI (Power Integrity)

IR drop and ground bounce analysis.
Optimization of decoupling capacitor placement.
PDN impedance verification.


🌡 熱解析 / Thermal Analysis

Heat distribution and hotspot detection.
Cooling efficiency validation (heatsink, thermal vias, airflow).
Thermal resistance verification between package and board.


📶 EMC/EMI 評価

Radiated and conducted emissions analysis.
Effectiveness of filters, shielding, and return path design.
Compliance with FCC, CISPR, VCCI standards.


🏭 DFM (Design for Manufacturability)

Check of clearance, drill size, aspect ratio.
Verification of solder mask, land size, and assembly feasibility.


🛠 解析手法 / Validation Methods

Simulation with SI/PI tools.
Measurements with oscilloscope, VNA, TDR, EMI chamber.
Accelerated reliability tests.
Design reviews with DRC/DFM automation.
