A Costly Perforation: Addressing Drill Break-Through to Protect PCB Manufacturing Yield Drill Break-Through Definition and Technical Meaning in PCB Manufacturing    Drill Break-Through refers to a condition in which a drilled hole penetrates beyond its intended layer boundary, unintentionally breaching adjacent copper layers or dielectric structures. While drilling is designed to create vias or th...

The Red Flag in Drilling: What Drill Break-Through Reveals About Your PCB Process Control Introduction: Why Drill Break-Through Deserves More Attention    In modern PCB manufacturing, drilling is often perceived as a mature and well-controlled process. CNC drilling machines are faster, more precise, and more automated than ever before. Yet, hidden within this seemingly stable operation is a subtle...

Controlled Depth Drilling: The Critical Process for Creating High-Density PCB Architectures Introduction: Why Controlled Depth Drilling Has Become a Structural Necessity in High-Density PCB Architectures    As electronic products continue to evolve toward higher functionality, smaller form factors, and increased integration, traditional printed circuit board architectures are rapidly approaching t...

Unlocking Space and Reliability: The Strategic Advantage of Controlled Depth Drilling Introduction    As printed circuit boards (PCBs) evolve toward higher density, thinner profiles, and increased functional integration, traditional through-hole interconnection strategies are no longer sufficient. Designers and manufacturers now face a fundamental challenge: how to increase routing freedom and ele...
