Why Multilayer PCBs Became Standard As electronic systems evolved from simple circuits to highly integrated platforms, single-layer and double-layer PCBs quickly reached their limits. Multilayer PCBs—typically defined as boards with 4 or more layers—became the standard solution for handling increased complexity. By stacking multiple conductive and insulating layers, engineers can: Route more signals within limited...
Blind and Buried Vias in HDI PCB Design: Engineering Principles, Manufacturing Constraints, and KKPCB’s Advanced Capabilities As high-density interconnect (HDI) technology becomes essential in 5G, wearables, automotive radar, aerospace, and compact IoT systems, PCB designers increasingly rely on blind vias and buried vias to meet aggressive space, performance, and reliability requirements. These via structures allow...
Engineering Context / Abstract Advanced automotive radar and ADAS (Advanced Driver Assistance Systems) platforms demand high-frequency PCB substrates capable of precise phase stability, minimal signal loss, and consistent performance under extreme thermal cycles and vibration. High-density radar modules operating in 77–81 GHz bands are particularly sensitive to dielectric fluctuations, EMI, and thermal expansion, which can...
What is a High Current PCB? A High Current PCB is a printed circuit board specifically engineered to carry significant electrical current—ranging from several amperes to hundreds of amperes—without excessive heat generation, voltage drop, or reliability issues. Unlike standard PCBs, high current designs must address resistive losses (I²R), thermal buildup, and mechanical stress. If not...

As a trusted PCB manufacturer, KKPCB supports global medical device companies with Class 3-compliant, high-reliability PCBs designed for critical healthcare applications. What Is a Medical PCB? Medical PCBs are the...
For standard SMT PCBs, surface finish is often selected for solderability, storage life and cost. But for RF, microwave, high-speed PCB, HDI, fine-pitch, radar, satellite communication, 5G RF and defense communication PCBs, surface finish can become part of the electrical performance discussion. The key question is not simply: Which gold finish is better? The better...
