AI training and high-performance computing have extremely high demands on data processing speed, energy efficiency, and memory bandwidth. Therefore, chips such as GPU, TPU, and NPU commonly adopt high-density advanced packaging, including HBM stacking, Chiplet modular integration, TSV through-silicon vias interconnection, and RDL redistribution architectures.
This type of packaging has characteristics of high frequency, high power, and high thermal load. During system operation, it is accompanied by risks such as uneven thermal delay, package warpage, interface fatigue, and shortened bump joint lifespan. If the internal structure, thermal behavior, and material interaction of the packaging cannot be grasped in a timely manner, reliability issues are likely to arise during mass production or long-term operation.
MA-tek's core capabilities in the field of AI and high-performance computing are:
Can simultaneously establish the true cross-section of the packaging structure, stress/thermal behavior models, and corresponding failure mechanisms.
Through high-resolution structural reconstruction, packaging thermal behavior analysis, interface material tracking, and lifetime verification, we assist customers in gaining an understanding of packaging stability under extreme conditions during the R&D phase, reducing yield loss in later stages, and supporting products in high power and long-duration computing scenarios.
