UHDI Fundamentals: UHDI Bleeding-edge Entertainment Applications, Part 2

02/06/2025 | Anaya Vardya, American Standard Circuits
Ultra high density interconnect (UHDI) technology is revolutionizing bleeding-edge entertainment applications by enabling compact, high-performance devices that push the boundaries of immersion, interactivity, and realism. Part 2 focuses on how UHDI is advancing the entertainment industry, particularly gaming.

Happy’s Tech Talk #37: New Ultra HDI Materials

02/03/2025 | Happy Holden -- Column: Happy’s Tech Talk
Some new materials have been introduced in the past year for ultra high density interconnect (UHDI), a convenient title for developing high density technologies. They have received labels like semiconductor-like PCBs (SLPs), redistribution layers (RDL), flip-chip ball grid array (FCBGA), and interposers. The early 2000s saw the creation of these organic substrates for flip-chip IC packaging. The initial construction was composed of a BT core with build-up layers of the Ajinomoto Build-up Film (ABF)
