How Resin Plugging Enhances PCB Performance
Introduction
PCB manufacturers use resin plug technology to improve circuit performance, reliability, and longevity. This process is particularly important in high-frequency and high-density PCBs.
What is a Resin Plug?
A resin plug is a sealed via filled with epoxy resin, typically used in multilayer PCBs to prevent contamination, improve electrical conductivity, and enhance mechanical strength.
Benefits of Resin Plugging
- Prevents short circuits by sealing vias.
- Enhances mechanical strength and durability.
- Reduces thermal stress, improving heat dissipation.
Resin Plugging Process
- Drilling the Via – The hole is created.
- Filling with Resin – A liquid epoxy is injected into the via.
- Curing & Surface Finishing – The board is hardened and leveled.
Conclusion
Resin plugs enhance PCB longevity and reliability, making them essential in high-tech applications.
