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 International Group Awarded IPC-4101/40 QPL Certification
May 22, 2018 | IPCEstimated reading time: 1 minute
IPC's Validation Services Program has awarded Ventec International Group, a global electronics materials manufacturing company headquartered in Suzhou, China, a second IPC-4101 Qualified Products Listing (QPL). Ventec successfully qualified their products, VT-90H and VT-901, to specification sheet 40 of IPC-4101E, Specification for Base Materials for Rigid and Multilayer Printed Boards.
Ventec, which manufactures and sells polyimide and high reliability epoxy laminates and prepregs, completed an intensive two-day audit where its manufacturing practices, test methods and conformance requirements of IPC-4101 were reviewed. Ventec met or exceeded the IPCs Validation Services QPL requirements for producing base materials used by printed circuit board manufacturers in the electronics industry. As a result, the company is successfully listed as an IPC-4101 trusted source capable of manufacturing in accordance with industry best practices to specification sheets 40 and 41. Ventec and other trusted sources of suppliers can be found on IPC's QML/QPL (Qualified Product Listing) database.
Mark Goodwin, COO USA & EMEA of Ventec International Group commented, "The IPC Qualified Product Listing (QPL) of our polyimide laminate and prepreg provides an independent endorsement of the quality of our production controls and materials for use in high reliability mil/aero applications. The IPC QPL is a trusted reference list for the entire electronics supply chain and we are delighted to be the first copper clad laminate manufacturer to have a polyimide material added to the validation services listing by meeting the requirements of both the rigorous facility audit and the qualification testing program at an independent test laboratory. We are fully committed to consistently meet and exceed the strict requirements of industry standards such as IPC-4101E."
IPC's Validations Services QPL/QML Program was developed to promote supply chain verification. It also provides auditing and certification of electronics companies' products and identifies processes which conform to IPC standards. "Ventec has differentiated itself from the competition in the polyimide market by becoming part of IPC's global network of trusted industry sources," said Randy Cherry, IPC director of Validation Services. "We are pleased to recognize Ventec for becoming a trusted supplier conforming to IPC-4101E."

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?
