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.

Ventec Launches Dk 3.48 Ceramic-Filled Hydrocarbon Thermoset Material
May 15, 2018 | Ventec International Group Co., Ltd.Estimated reading time: 1 minute
Ventec International Group Co., Ltd. has added to its extensive signal integrity laminate and prepreg range with the launch of tec-speed 20.0, a ceramic-filled hydrocarbon thermoset material designed for high frequency applications. tec-speed 20.0 combines unrivalled high-frequency performance (Dk 3.48 / Df 0.0037), superior loss characteristics and the highest reliability with fast availability and efficient delivery through Ventec’s fully controlled and managed global supply chain and technical support-network.
No More Compromises - Performance, Price and Availability
The tec-speed 20.0 (VT-870) is designed for the world's most demanding high frequency Printed Circuit Board applications such as cellular base station antennas, power amplifiers, LNB for broadcast satellites, automotive radar and RFID. With tec-speed 20.0, Ventec has responded to customer demands for a high-performance, reliable and cost-efficient high frequency material that also has a fast and efficient global delivery promise and dependable technical support.
The tec-speed 20.0 is a high-frequency laminate designed to preserve signal integrity up to high-GHz frequencies and has extremely low 3.48 dielectric constant (Dk) and 0.0037 dissipation factor (Df). By minimizing insertion losses, tec-speed 20.0 provides greater freedom to optimize copper trace widths, spacing, and PCB thickness.
Tested according to IPC-TM-650 specifications, the industry’s gold standard, tec-speed 20.0 is UL approved, reliable and durable, offering outstanding thermal performance. High glass transition temperature (Tg), high peel strength, and low CTE ensure structural integrity and reliability, in process and hardworking applications.
Now, tec-speed 20.0 is available as laminate or prepreg (VT-870PP), as standard with HTE copper foil or with HVLP (Hyper Very Low Profile) foil to attenuate passive intermodulation (PIM) effects.
The tec-speed 20.0 ceramic-filled hydrocarbon thermoset material is manufactured by Ventec using strict quality-controlled processes that are certified to AS9100 Revision D, ISO/TS16949 and ISO 9001:2015, and, like all Ventec products, is backed by a fully controlled and managed global supply chain, sales- and support-network.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
07/11/2025 | Andy Shaughnessy, Design007 MagazineThis week, we have quite a variety of news items and articles for you. News continues to stream out of Washington, D.C., with tariffs rearing their controversial head again. Because these tariffs are targeted at overseas copper manufacturers, this news has a direct effect on our industry.I-Connect007 Editor’s Choice: Five Must-Reads for the Week
Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.
Trump Copper Tariffs Spark Concern
07/10/2025 | I-Connect007 Editorial TeamPresident Donald Trump stated on July 8 that he plans to impose a 50% tariff on copper imports, sparking concern in a global industry whose output is critical to electric vehicles, military hardware, semiconductors, and a wide range of consumer goods. According to Yahoo Finance, copper futures climbed over 2% following tariff confirmation.
Happy’s Tech Talk #40: Factors in PTH Reliability—Hole Voids
07/09/2025 | Happy Holden -- Column: Happy’s Tech TalkWhen we consider via reliability, the major contributing factors are typically processing deviations. These can be subtle and not always visible. One particularly insightful column was by Mike Carano, “Causes of Plating Voids, Pre-electroless Copper,” where he outlined some of the possible causes of hole defects for both plated through-hole (PTH) and blind vias.
Trouble in Your Tank: Can You Drill the Perfect Hole?
07/07/2025 | Michael Carano -- Column: Trouble in Your TankIn the movie “Friday Night Lights,” the head football coach (played by Billy Bob Thornton) addresses his high school football team on a hot day in August in West Texas. He asks his players one question: “Can you be perfect?” That is an interesting question, in football and the printed circuit board fabrication world, where being perfect is somewhat elusive. When it comes to mechanical drilling and via formation, can you drill the perfect hole time after time?
