  • Overview

    The need for high density, high performance, and cost effectiveness has helped speed the development of System-on-a-Chip (SoC) and System in a Package (SiP). The most current assembly technology is the Multi-Chip Module (MCM) package. It integrates different functions of chips such as microprocessors, memory, logic, optic ICs and capacitors, onto mini-substrates, instead of placing individual packages onto a large PCB (also known as second level package).


    ASE’s MPBGA (Multi Package Ball Grid Array) utilizes the MCM assembly method. It employs the latest IC packaging technology for high-density products. The electrical and thermal performance and the affordability of the MPBGA package enables system designers to integrate several devices (Known Good Die) onto a single IC package. ASE has been in volume production since Q1, 2002.

    The integration of several semiconductor technologies onto a single MPBGA package offers excellent advantages for many applications where size, weight, electrical performance, and board density are critical requirements. The high-speed performance and improved thermal capability of the MPBGA package are also excellent for personal computing, networking, graphic chip, data communication, consumer IC, telecommunication, analog/digital, ASIC, and memory applications.
