Current IssueThe Hole Truth: Via Integrity in an HDI World
From the drilled hole to registration across multiple sequential lamination cycles, to the quality of your copper plating, via reliability in an HDI world is becoming an ever-greater challenge. This month we look at “The Hole Truth,” from creating the “perfect” via to how you can assure via quality and reliability, the first time, every time.
In Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.

Congressman Emmer Visits Chaska-Based Circuit Board Manufacturer
July 7, 2023 | Congressman Tom EmmerEstimated reading time: Less than a minute

On Wednesday, Congressman Tom Emmer (MN-06) toured Pro-Tech Interconnect Solutions. Pro-Tech’s Chaska facility has 83 employees and manufactures printed circuit boards for the military, aerospace, medical and commercial industries.
“Manufacturing products like chips and semiconductors here at home doesn’t just provide good-paying jobs to Minnesotans. Investing in the production of this essential technology is important to our national security,” Emmer said. “Thank you to the team at Pro-Tech for sharing their work with us.”
Pro-Tech President Melanie Bera Anderson added, “Pro-Tech Interconnect Solutions LLC is the only 100% woman-owned and operated “rigid” printed circuit board manufacturer in the USA. We build boards for the F35 Jet, medical implants and equipment, to commercial controls.”
Printed circuit boards like the kind produced by Pro-Tech are used in virtually all electronic products. However, only about four percent of printed circuit boards are produced domestically.
Pro-Tech was founded in 1968, and since 2018 has been operated by the woman-owned American Circuit Corporation.
