Cross-Talk/Noise/Interference Reduction TRIZ Cases
- Wiring Member Connection Structure for Common Mode Noise Suppression
Anti-parallel conductive lines in a flat cable harness cancel radiated electromagnetic fields between main and daughter boards.
- Ferrite Wafer Connector Assembly for PCB EMI Suppression
A connector assembly integrates a magnetic wafer cup to align terminal pins with conductive through-holes on the printed circuit board.
- Circuit Substrate Wiring Parasitic Capacitance Uniformization
Varying insulating layer width around circuit substrate wiring to manage parasitic capacitance distribution.
- Multilayer PCB Sublaminates Mitigating Swiss Cheese Effect
Segmented power and ground sublaminates lower via density to mitigate the swiss cheese effect and increase current carrying capacity.
- Power Circuit Noise Loop via Conductive Plate
A conductive plate connects rectifier wires and a ground terminal to form a dedicated noise loop, restricting propagation to the system power supply.
- Immunity Evaluation System for Circuit Board Noise Resistance
An immunity evaluation system estimates signal levels reaching IC terminals using near-field probe coupling characteristics.
