Electronic Component Analysis

Semiconductor integrated circuits are the core components of electronic products and are critical to the quality control of electronic devices such as diodes, resistors, and printed circuit boards (PCBs). In order to support the development of SiC and other next-generation power devices, Alfa Chemistry has conducted research on wafer analysis, chip structure, and module microstructure, and proposed corresponding solutions.

We investigate and analyze the causes of failures of LSI products, individual electronic components, and electronic parts to help improve quality control and increase customer product development efficiency and increase product yield. Using our rich research experience as a backing, we can satisfy customers' problem-solving needs through effective investigations and quick responses.
