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.

Fine-Line Circuits Ltd - India to Exhibit at International Microwave Symposium (IMS) 2023
May 15, 2023 | Fine-Line Circuits Ltd - IndiaEstimated reading time: 1 minute

Abhay Doshi, Managing Director of Fine-Line Circuits Ltd, has announced that his company will be exhibiting at this year’s International Microwave Symposium (IMS) to be held June 11-17 at the San Diego Convention Center in San Diego, CA.
It is Fine-Line’s mission to provide PCBs and PCBAs that deliver to the customer the RF performance they expect. They achieve this by working with every customer from the start through material selection, design optimization and final simulation, material stocking, PCB fabrication, and PCBA assembly to ensure expected precise RF performance.
When making this announcement Mr. Doshi said, “This is an excellent symposium and exhibition for us as we continue to increase our share of PCB supplies to the RF market. For a number of years now have been focused on RF and Microwave Systems requirements and the IMS 2023 symposium gives us the opportunity to talk to other like-minded individuals about this growing segment of the Electronics market. We look forward to meeting and talking with potential partners and customers in San Diego in June.”
Fine-Line Circuits will exhibiting in Booth 1713 sharing their expertise on providing the ideal surface finish for RF Microwave PCBs – Electrolytic Thick Gold Direct on Copper which gives a great skin and no Nickel related signal losses giving the designer the precise RF performance that the system is designed for.
Fine-Line has built a variety of PCB boards (hybrids, cavities, copper back, oversized PCBs) for a variety of Space and Defense Applications and other various systems (satcoms, radar, antenna, dividers, amplifiers, etc).

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.
