Impedance matching in HDI ( High- Density Interconnect ) boards is intended to prevent transmission errors, especially losses caused by transmission line resistance and the dielectric properties of the printed circuit board. Microvias can be used to create manufacturing-friendly PCB layouts in impedance-matched systems. BGA escape routing and dogbone fanout structures enable impedance matching in HDI PCBs. When do PCB traces...
Why BGA Assembly Is Critical in Modern PCB Design As electronic devices move toward miniaturization, high-speed performance, and high pin-count integration, the Ball Grid Array (BGA) assembly has become a mainstream packaging technology in: Microprocessors (CPU/GPU) FPGAs High-speed communication ICs Memory devices (DDR, LPDDR) Compared with traditional packages (QFP, SOP), BGA offers: Higher I/O density...
