Why Does the PCB Industry Still Use Gerber?

Every so often, I hear technologists ask why so many PCB designers still use Gerber. That is a fair question. Ucamco has over 35 years of experience in developing and supporting cutting-edge software and hardware solutions for the global PCB industry. Our customers—small, medium, and large PCB fabricators—include the electronics industry’s leading companies, and many of them have been with us for over 30 years. We are dedicated to our industry and excellence in everything we do, which includes our custodianship of the Gerber format.

Design For Excellence: Karen McConnell on Standards

During the IPC Summer Meetings, I spoke with Karen McConnell, senior staff CAD CAM engineer with Northrop Grumman Mission Systems. Karen is a veteran PCB designer as well as an IPC committee chair and mentor. She offered an update on some of the IPC committees she chairs, the need for more mentor programs in this industry, and why you can call something a ham sandwich if you define it correctly in the standard.

IPC-2581 Continues to Flourish

Because standards adoption in this industry tends to be akin to turning around a battleship, what is often seen as new has generally already been in production for 10 years or more. Often, there are outside influences and dependencies that cause this, so most of us tend to take a “wait-and-see” approach—let others shake out the issues. And even then, we only look at adoption if the mandate comes from higher-ups in the organization. It works the way we do it now, so why change?

Meet George Milad, I-Connect007 Columnist

So Many Standards Committees, So Little Time

During the IPC Summer Meetings and Panelpalooza in Raleigh, North Carolina, I met with Leo Lambert, vice president and director of technology at EPTAC. We discussed IPC’s recent efforts to revamp the way standards are developed and interpreted as well as changes to training and education committees and a variety of methods for eliminating errors and duplicated comments when revising standards.

Asleep at the Wheel?

The October issue of SMT007 Magazine considers the current, ever-changing landscape of our industry—a landscape being reshaped by “industrious laziness.” We’re automating manual processes with the intent to make our results better. But, like autonomous vehicle enhancements, human awareness and supervision are required.

Communication, Part 4: The Top 5 Causes of Engineering Delays

In Part 4 of this series on how PCB fabricators and designers can better communicate, Bob Chandler from CA Design and Mark Thompson from Prototron Circuits address the top five causes of engineer delays.

Communication, Part 3: Why Do Board Shops Ask So Many Questions?

In Part 3, Bob Chandler from CA Design and Mark Thompson from Prototron Circuits speak with Steve Williams about the importance of preparing, sending, and receiving comprehensive (and ideally, perfectly complete) design data packages. If you’ve ever wondered why the CAM department asks you so many questions, read on.

Happy Holden Previews His AltiumLive Frankfurt Keynote

I recently sat down for an interview with Happy Holden, who is slated to give a keynote speech at this year’s AltiumLive event in Frankfurt, Germany. Happy gives a preview of his presentation, which is focused on smart factories and automation, and why artificial intelligence might improve PCB design and fabrication in the future.

Future of 'Substances and Materials in Products' Data Exchange Formats as Standards

This article provides a simplified, state-of-the-art description of the data exchange formats for standards covering substances and materials reporting in products and processes. It also reviews existing issues and new challenges shared with end users of the standards and companies represented by their trade associations with some solution proposals they could discuss.

Additive Electronics Conference Set for October 2019 Debut

Kelly Dack and Tara Dunn talk about the upcoming conference "Additive Electronics: PCB Scale to IC Scale" on October 24, 2019, hosted by SMTA in San Jose, California, and why it's an important event for people to attend—especially those involved in the design process.

Communication, Part 2: Design Data Packages

The first part of this six-part series highlighted ways that PCB fabricators and designers can better communicate, starting with how to qualify a board shop. In Part 2, Bob Chandler and Mark Thompson talk about the importance of preparing, sending, and receiving comprehensive (and ideally, perfectly complete) design data packages.

SMTA Additive Electronics Conference: Industry Trends

Mainstream PCB manufacturing is often limited to 50-75 microns (mm) line and space. But the electronics industry is evolving quickly. Propelled by the demand for more sophisticated electronics, PCB design is being tasked with finer lines, thinner materials, and smaller via sizes.

ODB++: Transforming Ideas Into Products

The ODB format originated with the objective of delivering on this need. The format was originally introduced for use by PCB fabricators, eliminating the need for a collection of CAM files in multiple formats—such as Gerber, Excellon, IPC-356, or even IPC-350, which was an early attempt to simplify this process. The key to the success of ODB was that it obtained industry acceptance.

New High-speed 3D Surface Imaging Technology in Electronics Manufacturing Applications

Line confocal sensors—and scanners based on them—are used in the imaging of surfaces, transparent materials, and multi-layered structures in various metrology and inspection applications on discrete parts, assemblies, webs, and other continuous products. Line confocal sensors operate at high speed and can be used to scan fast-moving surfaces in real-time as well as stationary product samples in the laboratory.

Standards: Why We Have Them and Live by Them

Have you ever designed a board but received feedback that it couldn’t be manufactured unless changes were made? Or maybe you’ve designed a complex board and sent it to the factory only to find out that the manufacturer didn’t build the board to your expectations? PCBs are becoming more complex, factory options are growing, and expectations for product life cycles are becoming longer.
