This ensures compliance with specifications like ±10% tolerance. Clients avoid signal integrity issues in applications such as RF or high-speed digital circuits, minimizing performance risks.
Microsection Analysis: Cross-sectional samples of the PCB are polished and examined under a microscope to assess layer-to-layer adhesion, copper plating thickness, and hole wall quality. This destructive but precise method confirms internal structural integrity. Clients receive documented proof of compliance with industry standards like IPC-6012.
Functional Circuit Validation: The PCB is powered up and tested under real-world operating conditions using automated test equipment (ATE). This verifies that all subsystems perform as designed, from power regulation to signal processing. Clients identify firmware or hardware conflicts early, accelerating debugging and final product launch.
