Performance and Reliability Comparison: Via Tenting vs. Via Plugging

Introduction

For mission-critical PCBs, performance and reliability are key concerns. The choice between via tenting and via plugging impacts factors such as durability, electrical stability, and environmental resistance.

Performance Factors

Impact on Reliability

• Via tenting provides basic protection but may not prevent contamination or solder wicking.
• Via plugging offers superior reliability by sealing the via completely, preventing failure risks.

Which One is More Reliable?

For basic electronic devices, via tenting is sufficient. However, for high-speed, high-density, or industrial applications, via plugging provides superior reliability. Choosing the right method depends on PCB usage, environmental exposure, and expected wear and tear.
