ASC Sunstone Circuits Boosts Domestic Manufacturing Capabilities with Integrated Via Fill Technology

Estimated reading time: 1 minute

ASC Sunstone Circuits, a leading provider of high-quality, quick-turn printed circuit boards (PCBs), is pleased to announce 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 transitioned from parent company American Standard Circuits (ASC) to the ASC Sunstone facility in Mulino.

This equipment transfer represents a deepening of the synergy between both facilities, providing customers with faster access to advanced fabrication techniques previously unavailable on site.

Streamlining Complex PCB Fabrication

The addition of dedicated via fill equipment allows ASC Sunstone to manage complex design requirements - such as conductive and non-conductive via fill - entirely in-house. This move is designed to:

• Reduced Lead Times: By integrating in-house via fill capabilities at the Oregon facility, ASC eliminates the need to transfer boards between plants or outsource specific processes. This localized control ensures that complex commercial designs stay on the fast track, maintaining industry-leading quick-turn delivery schedules.
• Enhanced Reliability: Bringing the via fill process in-house at the Oregon plant ensures total quality control over boards requiring flat surfaces for component mounting (via-in-pad). This provides customers with superior structural integrity and optimized assembly surfaces without the logistics of multi-site handling.
• Support for Advanced Commercial Designs: This equipment enables the Oregon plant to support tighter pitch designs and improved thermal management locally. By streamlining the production of sophisticated boards, ASC provides a faster, more efficient path for domestic prototyping and production.

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."
