The Registration Sweet Spot
Registration is underrated and underappreciated. The key is to ensure proper registration from layer to layer across the entire printed circuit board. It’s a holistic process requiring anticipation, prediction, precise attention at each step, and detailed data tracking and monitoring.

Altix Receives New Order for AcuReel XL Imaging SystemJuly 15, 2021 | ALTIX
Estimated reading time: Less than a minute
Altix is thrilled to receive its first order of its AcuReel XL from a major European FPC manufacturer. Dedicated to all FPC processes with an exposure area up to 500 x 1500mm, the AcuReel XL is the ideal contact exposure solution for automotive-related FPC production and other markets requesting extra-large imaging formats.
Alexis Guilbert, product manager, reveals more about the machine’s attributes: “With the production of EVs becoming mainstream, the need for high-density FPCBs is rising. From dashboard control systems to battery management systems (BMS), the automotive sector is driving innovation in imaging. A BMS not only monitors the batteries’ status but also optimizes the use of the battery cells – and this is where FPCs come into play by connecting individual cells’ sensors to the BMS. Overall, we are very proud that Altix is completely ready to satisfy this emerging market with both the AcuReel contact printers and Adix RtR direct imaging machines.
For this month's PCBAA Member Profile, the focus is on Hari Pillai, president, Technology Components, Sanmina. Hari says, "I think I’ve had a good dose of luck throughout my career. But beyond luck, I had a vision to become a general manager as far back as my undergraduate years. I made all my career decisions based on that. My evaluation criteria was always, “How does this opportunity get me closer to my goal?” Sometimes opportunities come from unexpected places."
Registration is one of the most important features for any PCB fabricator, but the capability for multilayers is a lot of work on the fabricator’s part. CAM settings, multilayer lamination, X-ray analysis, AOI measurements, imaging capability, and drill accuracy all play an important part in this capability. Software and panel parametric coupons are important because they aid in registration performance.
There are many ways, dozens to be sure, and most likely many more, to streamline a PCB design. My goal here is to pick a single-digit number of rules to abide by, that can be reasonably adhered to, and provide some bang for the buck. These rules are meant to reduce design scope creep, avoid PCB respins, and improve production yields.
November’s issue of Design007 Magazine had an excellent theme that evolved around design simplification. There were exceptionally good articles about how to reduce over-constrained or needlessly complex designs. One significant time-consuming category is the creation of many design files and drawings which lead to lengthy creation and interpretation time along with the considerable time to resolve conflicting or erroneous information.
On May 11, 2023, Reps. Blake Moore (R-UT) and Anna Eshoo (D-CA) introduced the Protecting Circuit Boards and Substrates (PCB) Act to Congress. In October, I had the great pleasure of discussing the bipartisan Protecting Circuit Boards and Substrates Act with Congressman Moore, who represents Utah’s First Congressional District. He shared his thoughts on how supporting and investing in the domestic PCB industry can help bolster American security.
