AI Technical Summary

Technical Problem

In electronic devices, as the number of speaker channels increases, the number of power amplifiers also increases, resulting in excessively large board area, which limits the promotion of multi-channel systems.

Method used

By setting at least two bare chips in the power amplifier chip, each bare chip having a power amplifier circuit, and encapsulating them as a single chip through a connection layer and pads, at least two power amplifiers are formed, reducing the board area occupied.

Benefits of technology

This effectively reduces the packaging cost and peripheral circuit components of power amplifiers, lowers development time and risk, and saves on the number of cutting tools and packaging time during the packaging process.
