Control of Conductor Etching Process in Printed Circuit Boards Copper etching is one of the most critical steps in printed circuit board (PCB) manufacturing, as it directly determines the accuracy and reliability of conductive circuit patterns. The term “printed circuit board” originates from this process, since etching is the final stage of photolithography used to...
A Double Layer HF PCB may appear structurally simple, yet in high-frequency engineering it provides a remarkably efficient platform for low-loss propagation, stable impedance, and predictable electromagnetic behavior. When RF designers need high-frequency stability without the cost or stackup escalation of multilayer PCBs, a Double Layer HF PCB offers the ideal balance between manufacturability and...
Introduction: Why PCB Prototype Engineering Defines Modern Electronics A PCB Prototype is no longer just a pre-production sample—it is the central engineering stage that determines product performance, manufacturability, reliability, and cost.In advanced electronics such as 5G, IoT, robotics, automotive, aerospace, AI edge computing, and industrial automation, a well-engineered PCB Prototype ensures signal integrity, thermal stability,...
Modern wireless systems—from 5G radio units and phased-array antenna modules to automotive radar and satellite communication terminals—demand PCBs that deliver high RF power handling, exceptional phase stability, and ultra-low loss. As antenna modules continue to shrink while operating at higher frequencies, selecting the correct laminate becomes a mission-critical design decision. Among all mid-frequency RF substrates,...
Heavy Copper PCBs: High-Current Solutions for Power Electronics As electronic systems evolve toward higher power density, stronger reliability requirements, and increasingly harsh operating environments, Heavy Copper PCBs have become indispensable across power electronics, automotive systems, industrial control, and energy infrastructure. Unlike standard PCBs—typically manufactured with 1oz–3oz copper—a Heavy Copper PCB is defined as any PCB...
