The 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.

Unimicron Germany Rises from the Ashes with New Smart Factory
April 30, 2018 | Pete Starkey, I-Connect007 and Michael Weinhold, EIPCEstimated reading time: 9 minutes

Prepreg was stored in a fully-automated clean-room at 6°C to maximise its shelf-life and avoid wastage. The material management system drew the required material from cold storage 24 hours in advance, to allow it to condition to ambient temperature before lay-up, and again all the handling was by robot. The whole lay-up operation was carried out in Class 1000 cleanroom enclosures.
Housed in their own enclosure were eight laminating presses—five heating and three cooling. One of the hot presses was capable of 400°C operation to enable fusion bonding of PTFE when required.

From the automated breakdown stations, the press plates returned through a surface-brushing machine for re-use, and the bonded panels proceeded to a trimming and edge-dressing station. This machine attracted a lot of spectators as its robot presented each panel four times to the trimming guillotine, once for each edge, then placed it on a table and swivelled to present a milling head that polished the edges and rounded the corners—fun to watch!

Designers Notebook: Basic PCB Planning Criteria—Establishing Design Constraints
07/22/2025 | Vern Solberg -- Column: Designer's NotebookPrinted circuit board development flows more smoothly when all critical issues are predefined and understood from the start. As a basic planning strategy, the designer must first consider the product performance criteria, then determine the specific industry standards or specifications that the product must meet. Planning also includes a review of all significant issues that may affect the product’s manufacture, performance, reliability, overall quality, and safety.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
07/18/2025 | Nolan Johnson, I-Connect007It may be the middle of the summer, but the news doesn’t quit, and there’s plenty to talk about this week, whether you’re talking technical or on a global scale. When I have to choose six items instead of my regular five, you know it’s good. I start by highlighting my interview with Martyn Gaudion on his latest book, share some concerning tariff news, follow that up with some promising (and not-so-promising) investments, and feature a paper from last January’s inaugural Pan-European Design Conference.
