Image forming apparatus, chip, and chip package to reduce cross-talk between signals

摘要

An image forming apparatus including an engine unit to perform an image forming operation, and a board unit to control the engine unit. The board unit includes at least one chip package that includes a chip. The chip includes first pads to transmit a first type of signal, a second pad to transmit a second type of signal, and a third pad interposed between the first and second pads, to reduce cross-talk between the first and second types of signals.
