20 PCB007 MAGAZINE I AUGUST 2024 Interview by Marcy LaRont I-CONNECT007 In this interview with Alex Girardot of Per- fect Point Precision Carbide Tools, we explore the pioneering advancements in drill bit tech- nology supporting high-tech fabrication. Alex leverages his 15 years of expertise in the PCB industry to discuss the critical role of coat- ing technology in enhancing drill bit perfor- mance. is technological leap increases accu- racy, especially in high aspect ratio builds, and nearly eliminates drill bit breakage. Perfect Point's innovative approach includes a hybrid flute design and active collaboration with cus- tomers to optimize their drilling processes through automation and tailored guidance. e discussion also highlights the challenges of working with exotic materials and com- pares diamond-coated to carbon-coated drill bits, emphasizing the adaptability required in North American fabrication environments. Marcy LaRont: Alex, let's start by learning about how you got into the industry and what your company does. Alex Girardot: I spent 12 years working at a printed circuit board shop in southern Califor- nia, primarily as a dry process engineer. at shop specializes in multilayer rigid-flex PCBs but also has a varied product mix, which con- stantly presents a diverse set of challenges when it comes to drilling/routing. From there, I moved to Perfect Point where I serve as a field Image source: Perfect Point
