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.

Nano System installs Tongtai 2-station drill machine at Colonial Circuits
February 15, 2016 | Nano SystemEstimated reading time: 1 minute
Nano System Incorporated has announced the installation of a Tongtai Model SD-216B CNC drilling machine at Colonial Circuits in Fredericksburg, VA. This machine is equipped with 160,000 rpm Westwind air bearing spindles and the NSI optical inner layer registration system. Automatic tool change with 300 tools per station; tool diameter, length, and dynamic runout check; and a blind via depth control system accurate to ± 20 microns will provide Colonial Circuits with industry leading capability to fabricate HDI multilayer PCB’s with very accurately placed blind and buried vias and line widths and spacing down to 50 microns.
About Colonial Circuits
Colonial Circuits is currently in its 35th year as a full service manufacturer of high quality circuit boards. The company's 60 dedicated employees serve military, space, and commercial markets from its 40,000 square foot facility in historic Fredericksburg, Virginia.
Colonial's capabilities include rigid, flexible, and rigid/flex, prototype through low volume offering a wide range of technologies including HDI, Blind/Buried vias, laser drilling, micro filled vias, controlled depth drill/rout, sequential laminations, hybrid-constructions/mixed laminates and heavy copper circuitry. Lead times as short as 24 hours make Colonial a prime choice for the industry's low volume, high reliability needs. For more information click here.

Preventing Surface Prep Defects and Ensuring Reliability
06/10/2025 | Marcy LaRont, PCB007 MagazineIn printed circuit board (PCB) fabrication, surface preparation is a critical process that ensures strong adhesion, reliable plating, and long-term product performance. Without proper surface treatment, manufacturers may encounter defects such as delamination, poor solder mask adhesion, and plating failures. This article examines key surface preparation techniques, common defects resulting from improper processes, and real-world case studies that illustrate best practices.
RF PCB Design Tips and Tricks
05/08/2025 | Cherie Litson, EPTAC MIT CID/CID+There are many great books, videos, and information online about designing PCBs for RF circuits. A few of my favorite RF sources are Hans Rosenberg, Stephen Chavez, and Rick Hartley, but there are many more. These PCB design engineers have a very good perspective on what it takes to take an RF design from schematic concept to PCB layout.
Trouble in Your Tank: Causes of Plating Voids, Pre-electroless Copper
