Connect the Dots: Five Best Practices for Designing Flex and Rigid-flex PCBs
APCT Increases Technology with Rigid Flex Optical Registration from DIS
April 8, 2021 | APCTEstimated reading time: 1 minute
APCT Inc has added Rigid Flex Optical Registration™ (RFS), developed by DIS Inc of Islandia, N.Y. to enhance their PCB registration capabilities. The RFS machine is built specifically to process difficult flex, rigid and rigid-flex jobs. Using DIS, Inc proprietary Optical Registration™ technology in conjunction with SmartWeld, the RFS has the ability to align inner-layers and pre-preg without the use of expensive pin-tooling.
Optical Registration™ allows for optical alignment of inner layers during the lay-up process of multi-layers and sequential build-up technology, eliminating the need to manually punch and pin individual layers prior to lamination. The tolerance build-up and variability associated with traditional pin lamination systems is eliminated.
A vision and positioning system sequentially align and clamp layers together utilizing a full platen, assuring coplanarity and accuracy. The aligned multi-layers are welded together with SmartWeld™, the patented coupled induction welding system developed by DIS Inc.
In addition, Optical Registration™ provides an opportunity to utilize X-ray inspection to quantify registration of welded multi-layers prior to lamination. The panel can then be measured after lamination, providing the data to analyze the lamination process and take corrective actions if necessary.
The process has been in use worldwide at both high tech and high-volume shops over the past several years. Some of the leading-edge requirements placed on PCB shops utilizing pin technologies are not able to be met unless they introduce Optical Registration.

IPC Hall of Fame Spotlight Series: Highlighting Patty Goldman
11/22/2024 | Dan Feinberg, I-Connect007In my first article of this special series, I wrote a synopsis of the IPC Raymond E. Pritchard Hall of Fame (HOF) Award, along with a commentary on its first few members, particularly Pritchard. Over the years, IPC members who have contributed significantly to IPC and our industry have been awarded this high honor and recognition. Though many early HOF members have passed away and are unknown to today’s IPC membership, their contributions still resonate. Over the coming months, I look forward to researching and reporting on IPC Hall of Fame members and their contributions. This month, I highlight Patty Goldman.

Enjoy the Journey: PCB Design Instructor Kris Moyer on His Sustainable Lifestyle
11/19/2024 | Michelle Te, IPC CommunityWhen I contacted IPC design instructor Kris Moyer to discuss his sustainable lifestyle, he responded to my text with a call. "I'm calling you from about 8,000 feet, sitting at the foot of Mammoth Lakes," he told me. “My friends and I are about to get in the pool for the afternoon." Kris can do this because he actually lives full-time in his travel-trailer at this campground. He's now a permanent camper, taking him anywhere the winds blow—and where there's strong internet service—so he can teach his PCB design classes, offer expert interviews, and live off the land.
