CCGAs Expose Brittle Supply Chain

摘要

FPGAS are a multibillion-dollar business, characterized by suppliers like Xilinx, Microchip, Texas Instruments and Cypress Semiconductor. So why are they reliant on a single source for copper-wrapped solder column attachment? And not just any source. Six Sigma is a small, founder-run Silicon Valley-based company. For more than 30 years, it has performed a variety of third-party services, including solder dipping, BGA reballing, and solderability testing. It also happens to be the sole supplier of copper-wrapped solder column attachment services to the major FPGA vendors. And according to industry watchers, that leaves the supply chain in something of a pickle.
