44 PCB007 MAGAZINE I MARCH 2023 needs no companion. In reality, the CHIPS Act doesn't solve supply chain problems because it doesn't adequately address the rest of the eco- system. Few officials we speak to have any idea that we don't have the adjacent manufacturing capacity to create the entire technology stack. ey don't know that we will be sending the chips made in the new fabs back to Asia for packaging. In this session of Congress, we will see new legislation introduced that would revital- ize American PCB manufacturing by fund- ing R&D and workforce development, as well as creating incentives to buy American-made PCBs. Congress needs to act this year to set this recovery in motion and finish the job the CHIPs Act started. is is not an overnight fight. It took us decades to get to where we are today, and it will take years to bring a meaning- ful amount of manufacturing back to the U.S. To be successful we need your help. By join- ing PCBAA, you are expanding your influence over the future of the industry and giving us more power in Washington. Many voices mat- ter. Join us, then contact your elected repre- sentatives and let them know how important this industry is to American high-tech manu- facturing.

Interview by Nolan Johnson Nolan Johnson speaks with Lothar Henneken, PhD, of Rob- ert Bosch GmbH, whose paper "Risk Prediction of Electro- chemical Migration on Elec- tronic Control Units—A Practical Approach," was of one of three papers that won the prestigious Best Technical Paper award in the Best of Conference cate- gory at IPC APEX EXPO 2023. [Dr. Henneken's] paper, which was presented during Techni- cal Conference Session S25: QRTI-Assembly Risk Prediction and Failure Analysis, on Wednesday, Jan. 25, sought to mathematically model the risk of elec- tronic failures in relation to climate-related factors, such as local humidity, as well as a device's physical properties and the voltage applied. Dr. Henneken, you received an award for one of the best technical papers at IPC APEX EXPO this year. Tell me about it. What was your topic? My paper is about the reliabil- ity of electronics depending on the situation they are in. In a harsh or humid environ- ment, the surface of electronic boards can get a little bit wet, which can cause undesirable parasitic currents or shorts; but determining the likelihood of such failures occurring is highly complex. It depends on the local humidity and the microclimate inside the device and the distances, so fine pitch components are more critical than larger components. It's also driven by the voltage that is applied. It's very important for the world because complexity is just going up and up, meaning that we have a higher risk of such failures.
