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 BT Epoxy PCB? A BT Epoxy PCB is a high-performance PCB built using BT epoxy resin (Bismaleimide-Triazine), a material widely used in IC substrate and semiconductor packaging applications. Compared to standard FR-4, a BT Epoxy PCB offers: Higher glass transition temperature (Tg) Lower dielectric loss Better dimensional stability Improved reliability under thermal...
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...
A Fine Line PCB is a printed circuit board that features extremely narrow traces and spacing, typically in the range of 2–4 mils (50–100 μm), allowing engineers to fit more functionality into a smaller board area. Fine line technology is critical for high-density, high-speed digital, RF, and precision analog circuits, where both space optimization and...
What is a Fine Line PCB? A Fine Line PCB is a printed circuit board designed with extremely narrow trace widths and spacing, typically below 100 microns.
