Real Time with... IPC APEX EXPO 2025: Revolutionizing PCB Manufacturing with Laser Technology from MKS' ESI
April 16, 2025 | Real Time with...IPC APEX EXPOEstimated reading time: Less than a minute

In this interview, Barry Matties speaks with Casey Krueger from MKS' ESI. MKS' ESI focuses on laser-based micro machining for PCBs, especially in HDI and IC substrates. The Geode CO2 drilling system, launched in 2019, uses AOD technology to transform the market. Trends show a shift toward smaller vias for advanced packaging, with laser drilling concentrated in Asia. North America sees rising investments in laser tech, prioritizing quality, productivity, and energy efficiency, while AI integration boosts MKS's operations.
The 25th IPC APEX EXPO, March 18-20, 2025, at the Anaheim Convention Center in California, has concluded successfully. If you couldn’t make it to the show, don’t worry—the I-Connect007 team has coverage of the entire week’s events.
