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.

DuPont, YMT Collaborate to Enhance Riston Dry Film Photoresist Distribution and Service in Korea
September 5, 2023 | DuPontEstimated reading time: 2 minutes

DuPont Interconnect Solutions (DuPont) announced that it entered into a strategic collaboration relationship with YMT, a Korean printed circuit board (PCB) materials manufacturer listed on the KOSDAQ exchange. This collaboration combines DuPont’s circuit imaging material expertise and YMT’s local network, which can best address the local customer needs with faster response, better service, and a total solution. Under this collaboration, YMT has invested in establishing a dry film slitting facility in Ansan, Korea, and expects facility operation in October.
“YMT is one of the leading companies in the global chemical material industry with strong technology development capability. We are pleased to work with YMT to advance the electronic industry and build a more connected value chain to serve our customers in Korea,” said Yuan Yuan Zhou, Global Business Director, Metallization & Imaging, DuPont. Adding the local Riston® dry film photoresist slitting capability will largely accelerate Riston® product delivery and flexibility, heightening Korea’s local customer reach and better service. “We believe the win-win strategy will reinforce our circuit imaging market in Korea while YMT will expand its current product offerings by adding Riston® dry films,” said Zhou.
”We are excited by growing our relationship with DuPont. By aligning more fully with DuPont, we can leverage our strength in technical service and logistics to meet the varied needs of our customers as the industry continues to grow. We are confident that our collaboration will create long-term value for our customers,” said Peter Baek, Chief of Business Officer, Vice President, YMT.
DuPont and YMT will jointly showcase the Riston® dry film photoresist technology at YMT booth #E401 in the upcoming KPCA on Sept. 6-8, at Songdo Convensia, Incheon, Korea. At the show, DuPont and YMT will present a broad Riston® circuit imaging materials designed for fine-line applications and advanced PCB technology for high-end segments such as Integrated Circuit (IC) substrate, High-Density Interconnect (HDI) and Semi-Additive Process (SAP) to drive high-integration, high-performance, and miniaturization process development.
Exhibited Product List:
- Riston® DI1600 & DI1700 dry film photoresist, the advanced fine line direct imaging photoresist solution for IC substrate application
- Riston® SD2000 dry film photoresist, super fine line stepper photoresist solution for IC substrate and advanced packaging application
- Riston® TH2000 dry film photoresist, the advanced dry film photoresist solution for fine line HDI and FPC application
- Riston® WBR3000 dry film photoresist, the advanced solution for tall copper pillar process in the advanced packaging application

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.

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.
