THE LEAD

As the Christmas holiday approaches, the US gets into the holiday spirit by announcing, then delaying, additional tariffs on semiconductor imports from China. Meanwhile, higher demand for consumer electronics such as gaming devices and TVs are tightening supplies of certain components. Merry, merry!

PCB UPdate will not be published on Dec. 26. We wish all our readers a happy holiday!
