Nistec Newsletter #25 – Enhancing PCB Performance with BackDrill
- September 16, 2024
The newsletter explains the BackDrill process, a technique used in printed circuit boards (PCBs) to enhance signal quality by removing excess copper plating from unused portions of drilled holes. This process reduces inductance and noise, improving the overall performance of the PCB. While BackDrill improves functionality, it comes with certain trade-offs, including higher production costs, longer manufacturing time, and restrictions on conductor routing near the drilled holes due to the larger drill size. Despite these challenges, BackDrill is valuable for high-frequency applications, particularly when optimizing signal integrity is critical.
