Show & Tell: IPC APEX EXPO 2018 is on the Books!


Reading time ( words)

I am home from another IPC APEX EXPO. I have been going to these things for more than 38 years, and I learn something each year.

I spent most of Monday attending the Design Forum, which is a set of classes specifically targeted at PCB designers. Up first was Dana Korf, an old hand at tooling and front-end engineering. He presented “Printed Circuit Board Factory 4.0,” a comprehensive program he and others are undertaking to develop a completely digital fabrication data package in a single .XML file, as outlined in Figure 1. The unfortunate truth is that less than 10% of all new orders arrive at the PCB fabricator’s facility with complete, accurate design data; most have missing or incorrect data. Another big issue is that a lot of the preliminary or front-end information is in the form of drawings and specifications that require reading and interpreting, and sometimes even further investigation, as it is often conflicting data. Dana wants all this data to be digital to drive a modern Industry 4.0 factory.

Dana went over the progress since the 1970s culminating in the current IPC-2581 standard, and additional software added to cover what the OEM is sending and what the factory needs. 

The digital modernization covered information for the BOM (ECAD and MCAD), mechanical fabrication, stackup, material requirements, impedance requirements, plating and surface finish, artwork, drawings, notes and requirements for acceptability. This information can support the requirements of the enterprise business system PLM/ERP.

Design Tips for Lowering Costs of Fab and Assembly

08/25/2022 | Cherie Litson, CID+, Litson1 Consulting
This is the million-dollar question of every project: How can I cut the cost of the PCB? There are about a thousand answers to this question. There are a few simple guidelines that everyone can follow to reduce costs. I talk about them in my IPC CID and CID+ courses. Designers, fabricators, and assemblers talk about them in a variety of articles. Some professionals who have published some great articles on cost-saving strategies include Tara Dunn, Happy Holden, Chris Church, Kella Knack, Judy Warner, Julie Ellis, Lars Wallin, and many, many others.

What Happens When You Assume?

07/05/2022 | I-Connect007 Editorial Team
What is design with manufacturing and what does true DWM look like in operation? In this interview, I-Connect007 columnist Dana Korf explains what it will take to achieve total communication among all the stakeholders in the PCB development cycle. He also stresses the need for everyone involved in PCB design and manufacturing to stop making assumptions, even at the risk of being labeled as “that guy” who asks too many questions.

Altium Invests in Future Designers

04/13/2022 | Andy Shaughnessy, Design007 Magazine
While at IPC APEX EXPO, I stopped by the Altium booth to visit with Rea Callender, vice president of education at Altium. Rea shared information about the company’s recent design competition for students around the world, as well as a new curriculum that is drawing interest from some unique locations.
