SPS can provide paper or electronic designs, but often the initial samples are
included with the design. Power module samples are often built to demonstrate design
feasibility and to allow preliminary performance testing. The feasibility samples are
often built with little or no tooling. The SPS facilities are very limited, and samples
are often built at the customers facility or at contract assemblers. The SPS facility does
have some basic assembly and test capability to resolve critical design issues, and to
build some engineering prototypes. In general, design validation and qualification samples
are built at the customer’s facility or at an SPS offshore contract assembler. The SPS laboratory is primarily for package and material evaluation, and is equipped to do the following types of tests for power packages, power modules and thermal substrates:
Package evaluation and modeling is considered as an integral part of any module, package or substrate design, and a key measure of how the package performs against target goals or specifications. |
