What is an Ultrathin BGA Substrate?
An ultrathin BGA substrate is a type of substrate used in the packaging of semiconductor devices. It serves as the base on which the semiconductor die is mounted and provides the necessary electrical connections between the die and the printed circuit board (PCB). Le “ultrathin” aspect refers to the reduced thickness of the substrate compared to traditional BGA substrates, enabling more compact and lightweight electronic packages.
BGA packaging involves placing solder balls in a grid pattern on the substrate’s bottom surface, which are used to create electrical connections to the PCB during the reflow soldering process. Ultrathin BGA substrates maintain the same functionality but offer reduced thickness, making them ideal for applications where space is at a premium.
