Product Description
High-Density Interconnect (HDI) Technology
High-Density Interconnect (HDI) utilizes microvias with a diameter of ≤0.15 mm, employing advanced fine-line patterning and microvia formation techniques to achieve interconnection of components within an ultra-compact form factor. Its architectural design — characterized by minimized conductor geometries and optimized layer stacking — enables a wiring density that is an order of magnitude higher than that of conventional printed circuit boards (PCBs), making it essential for high-performance miniaturized systems.
Electrical performance is significantly enhanced through precise control of parasitic effects: residual stub inductance is reduced, discrete decoupling capacitors are eliminated via integrated power/ground planes, and crosstalk is minimized through controlled impedance routing. Furthermore, through the strategic placement of thin HDI dielectric layers, radiated electromagnetic interference (RFI/EMI) is lowered by minimizing loop inductance and uniformly distributing capacitance, thereby optimizing signal integrity along high-frequency transmission paths.
