Flexible Circuit Technology Workshop #5 Tackles Structures, Applications, Materials, and Manufacturing Processes: Think and Plan in Three Dimensions!

In just 15 minutes, flex expert Joe Fjelstad will teach you about implementing this useful technology into your manufacturing operation. Joe suggests you start with defining your end-product requirements and understanding cost and product life cycle expectations, as well as end-user needs. He further addresses the many considerations with adopting this useful technology.

Stop Relating Trace Temperature to Current Density

Many design engineers and even many software suppliers make the significant mistake of equating changes in trace or via temperature with current density. This is incorrect at best and dangerous at worst. There is little if any correlation between temperature and current density. Current and trace dimensions (among other things) are the relevant variables, but current density is not. I hope by the end of this article you will see why. Here are four illustrations that will help you understand this.

Documenting Your Flex Circuit Design

As a flex circuit applications engineer, when I receive an RFQ, the first thing I do is look at the customer’s data and review their manufacturing notes. Quite often, I find notes that supersede IPC specifications in manufacturing documents, as customers often believe these added notes and associated specifications will make the circuit more robust. However, these non-standard IPC manufacturing specifications/notes can wreak havoc on the manufacturing process and can actually lead to a less robust circuit.

This Month in Design007 Magazine: Thermal Fundamentals With Mike Jouppi

The I-Connect007 team recently interviewed Mike Jouppi, one of the champions of thermal management in PCBs. Mike spent decades working on updating the old IPC current-carrying data, which dated back to the 1950s, and he is the primary architect behind IPC-2152— the standard for determining current-carrying capacity in printed board design. As Mike explained in this wide-ranging interview, even if you’re using the latest thermal design software, you still need to have a firm understanding of the fundamentals.

The Role of EDA Tools in Creating Fab Notes

When discussing fab notes, there’s a lot of focus on what designers should and should not include in the package. But what is the role of EDA tools in this process, and can intelligent data formats streamline the tasks and help eliminate fab notes that are less than fantastic? In this interview, Pat McGoff, market development manager for Mentor, a Siemens Business, speaks frankly about fab notes and what EDA tool companies like Mentor can do to automate this process.
