Fairchild Semiconductor AN-5026 Using BGA Packages Application Note
The document introduces the Fine-Pitch Ball Grid Array (FBGA) package as a solution to space and weight requirements in personal computing and portable electronics. It highlights BGA advantages such as smaller size, larger pitch, lack of fragile leads, improved board assembly yields, and better thermal properties compared to QFP or TSSOP packages.
The note provides detailed routing techniques for different bit-count devices (18-bit, 24-bit, 32-bit, 36-bit, 40-bit, and 48-bit) using specific Fairchild models like the 74LCX16500 and FST32211. It also covers power and ground routing methods via vias under or outside the package, as well as advanced via types including blind, buried, and micro vias for high-density designs.
