ASC Sunstone Circuits, a leading provider of high-quality, quick-turn printed circuit boards (PCBs), announced a significant enhancement to its Oregon manufacturing facility. As part of a strategic initiative to align capabilities across the organization, a high-precision via fill machine has been transferred from parent company American Standard Circuits to the ASC Sunstone facility in Mulino.

The equipment transfer deepens operational synergy between the two facilities and provides customers with faster access to advanced fabrication techniques that were previously unavailable on-site.

Streamlining Complex PCB Fabrication

The addition of dedicated via fill equipment enables ASC Sunstone to handle complex design requirements, such as conductive and non-conductive via fill, entirely in-house. The move is intended to deliver several benefits:

• Reduced lead times: In-house via fill capability eliminates the need to transfer boards between plants or outsource specific processes, keeping complex commercial designs on fast-track, quick-turn schedules.
• Enhanced reliability: Performing via fill locally ensures full quality control for boards requiring flat surfaces for component mounting (via-in-pad), improving structural integrity and assembly performance without multi-site handling.
• Support for advanced commercial designs: The new capability allows the Oregon plant to support tighter pitch designs and improved thermal management, streamlining domestic prototyping and production of sophisticated boards.

A Unified Manufacturing Strategy

"Since joining forces with American Standard Circuits, our goal has been to provide the best of both worlds: ASC’s vast technical resources and Sunstone’s legendary speed and ease of use," said Mathew Stevenson, VP & General Manager at ASC Sunstone Circuits. "Moving this via fill capability to Oregon is a perfect example of that synergy. We are literally putting the tools for complex engineering directly into the hands of our quick-turn customers."
