Waveguide window ventilation board

Common Causes of Shielding Performance Loss in Ventilation Panels

At MAT Aviation Manufacturing Co., Ltd., ventilation panels are critical. Airflow. EMI shielding. Any loss affects system reliability.

Materials inspected first. Substrates. Metal sheets. Coating powders. Check surface. Check thickness. Reject cracks, chips, contamination. Out-of-spec batches removed. Do not use in production.

Assembly monitored. Waveguide channels aligned. Panels installed correctly. Gaps create EMI leakage. Operators check alignment continuously. Correct immediately.

Coating applied. Thickness and coverage monitored. Uneven coating weakens shielding. Inspect multiple points. Fix deviations immediately.

Environmental factors monitored. Humidity. Dust. Corrosion. Can reduce conductivity. Panels stored in controlled conditions. Inspect before installation.

Wear and damage tracked. Scratches, dents, bends. Physical damage reduces shielding. Inspect during maintenance. Replace compromised panels.

Design checked. Aperture size. Channel length. Material conductivity. Must match system requirements. Wrong design reduces attenuation. Engineering validation required.

Traceability maintained. Material batch. Substrate type. Coating date. Inspection results. Any performance loss traced and corrected.

Operators follow SOPs. Inspect materials. Monitor coating. Verify assembly. Control environment. Track every batch.

Consistency ensures reliability. Panels perform as expected. Airflow maintained. EMI shielding intact. Systems operate without failure.
