What is a High Layer Count PCB? A High Layer Count PCB refers to a multilayer printed circuit board with a large number of layers, typically 10 layers and above, and often reaching 20, 30, or even 50+ layers in advanced applications. A high layer count PCB is designed to handle complex routing, high-speed signals,...
What is a Buried Via PCB? A Buried Via PCB is a multilayer printed circuit board where vias are located between internal layers only, without extending to the outer layers. Unlike through-hole vias, a buried via PCB allows connections between inner layers while keeping the outer layers free for routing, enabling higher circuit density and...
What is an HDI PCB? An HDI PCB (High-Density Interconnect PCB) is an advanced printed circuit board designed with higher wiring density per unit area, using technologies such as microvias, fine lines, and sequential lamination. Compared to conventional PCBs, an HDI PCB enables more compact layouts, improved electrical performance, and higher signal density, making it...
What is a Fine Line PCB? A Fine Line PCB refers to a printed circuit board with extremely narrow trace width and spacing, typically below 100 μm (4 mil) and often reaching 50 μm (2 mil) or less in advanced designs. These PCBs are essential for high-density interconnect (HDI) and miniaturized electronic products, where space...
What Is a Fine Line PCB? A Fine Line PCB refers to a board manufactured with extremely narrow trace width and spacing, typically: ≤100 µm (4 mil) → standard fine line ≤75 µm (3 mil) → advanced ≤50 µm (2 mil) or below → ultra-fine line These geometries go beyond conventional PCB fabrication limits and...
Why Microvias Are Critical in Modern PCB Design As electronic devices continue to shrink while performance demands increase, traditional through-hole vias become a limiting factor. Microvias solve this by enabling high-density interconnects with shorter electrical paths. They are essential when: BGA pitch ≤ 0.8 mm (especially ≤ 0.5 mm) Routing congestion limits layout feasibility High-speed...
System Complexity as the Driving Force Modern electronic systems are no longer defined by individual components, but by highly integrated devices with massive I/O requirements. CPUs, GPUs, FPGAs, and advanced SoCs now feature hundreds to thousands of pins, driving the need for High Pin Count PCBs. This shift introduces a new level of complexity: Multiple...
Why High Pin Count Matters As modern electronic systems evolve, integrated circuits such as CPUs, GPUs, FPGAs, and high-speed SoCs demand hundreds or even thousands of I/O connections. A High Pin Count PCB is designed to support these devices by enabling dense interconnections within limited board space. Unlike standard PCB designs, high pin count boards...
What Makes Probe Card PCBs Unique A Probe Card PCB is not a typical circuit board—it is a high-precision interface platform used in semiconductor wafer testing. It connects test equipment (ATE) to microscopic pads on silicon wafers through probe needles or MEMS structures. Unlike standard PCBs, probe card boards must support: Ultra-fine pitch interconnections High...
Why Buried Vias Matter As electronic systems become more compact and performance-driven, traditional via structures are no longer sufficient for complex routing requirements. A Buried Via PCB enables connections only between internal layers, eliminating unnecessary vertical paths through the entire board. This design approach is not just about saving space—it is about engineering control over...
