I-Connect007 Editor’s Choice: Five Must-Reads for the Week
April 18, 2025 | Andy Shaughnessy, Design007 MagazineEstimated reading time: 2 minutes

It’s been a busy week in our industry. Never a dull moment! If you’ve been paying attention to our tariff tumult with China and its effect on the stock market, especially if your company does a lot of business with China, you might be tempted to call in a Xanax refill about now. But hang tight. This is still early in the first quarter. This brouhaha serves to underscore our need to manufacture critical laminates and components in the U.S.
In this week’s must-reads, we have a potpourri of articles covering tariffs, the next generation of HDI, the three-year anniversary of IPC Mexico, a novel green technology, and emerging design trends. And we’re right in the middle of trade show season. I’ll be at SMTA Atlanta April 24 and PCB East April 30. I hope to see you on the road!

When I first started covering this industry in 1999, HDI was the hot, new upcoming technology. Now, we’re approaching the next wave of HDI. What does this entail for PCB designers and fabricators? As Jerome Larez points out in his column, much of the push for the next generation of HDI is driven by the need for improved signal integrity, Moore’s Law, and the demands of 5G and wearables.
