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

The Evolution of Picosecond Laser Drilling
06/19/2025 | Marcy LaRont, PCB007 MagazineIs it hard to imagine a single laser pulse reduced not only from nanoseconds to picoseconds in its pulse duration, but even to femtoseconds? Well, buckle up because it seems we are there. In this interview, Dr. Stefan Rung, technical director of laser machines at Schmoll Maschinen GmbH, traces the technology trajectory of the laser drill from the CO2 laser to cutting-edge picosecond and hybrid laser drilling systems, highlighting the benefits and limitations of each method, and demonstrating how laser innovations are shaping the future of PCB fabrication.

Preventing Surface Prep Defects and Ensuring Reliability
06/10/2025 | Marcy LaRont, PCB007 MagazineIn printed circuit board (PCB) fabrication, surface preparation is a critical process that ensures strong adhesion, reliable plating, and long-term product performance. Without proper surface treatment, manufacturers may encounter defects such as delamination, poor solder mask adhesion, and plating failures. This article examines key surface preparation techniques, common defects resulting from improper processes, and real-world case studies that illustrate best practices.
RF PCB Design Tips and Tricks
05/08/2025 | Cherie Litson, EPTAC MIT CID/CID+There are many great books, videos, and information online about designing PCBs for RF circuits. A few of my favorite RF sources are Hans Rosenberg, Stephen Chavez, and Rick Hartley, but there are many more. These PCB design engineers have a very good perspective on what it takes to take an RF design from schematic concept to PCB layout.
