Co-Packaged Optics Testing Faces Steep Data Center Ramp


Key Takeaways: Device interface board must balance flexibility in handling with customization for different optical connectors. Test fixtures should account for DUT socketing challenges, such as warpage, coupling, and interference. Advanced data management practices will help speed yield learning. Integrating photonic and electrical ICs into co-packaged optics (CPO) requires... » read more

Balancing Parallel Test Productivity With Yield & Cost


Parallel test is used for nearly every device produced by fabs and OSATs, but it can reduce yield and increase the cost of test boards and operations. This is a well-understood tradeoff for ensuring consistent test accuracy across multiple sites and reducing test time. Collectively, ATEs and multi-site test boards — DUT interface boards (DIBs), probe cards, and load boards — significantl... » read more
