All About Flex: Why Copper is Ideal for Flexible Circuitry

Copper is the second-most conductive metal (in pure form). The copper used on flexible circuits can be formed by a number of methods such as electro-deposition (ED), rolling/annealing, or a combination of the two. The conductivity of copper by volume on a flexible circuit is not exactly the same as pure copper, but it is quite close.

Catching up with…PNC: Open House Planned for May

I’m a great believer in open houses. Any time customers and vendors get together to learn and talk about what they can do for each other it’s a good thing. That’s why, when I heard that PNC, in Nutley, New Jersey, planned to hold an open house on May 20, I wanted to learn more about it. So I called my friend Sam Sangani, the company’s owner, to learn more about it.

Karl's Tech Talk: Green Legislation and the Impact on Electronic Materials and Processes

In general, “green” and “environmentally friendly” refer to manufacturing that involves the replacement of toxic substances with less toxic materials, the elimination of materials or processing steps, less consumption of chemicals (i.e., more efficient or higher yield processing), reduction of water use, reduction of energy use, less space requirement (i.e., smaller equipment footprint), recycling, and on-site recovery of materials.

Happy’s Essential Skills: Design of Experiments

Design of experiments (DOE) is one of the most powerful and influential engineering tools for product yield improvements, new products or processes development, or for problem solving. As mentioned in my last column, process problems led me to a career in printed circuits, and quickly solving those problems led me to a bonus stock award and a great life. Even though I knew nothing about printed circuit manufacturing processes, I was able to quickly find the root causes of all the problems and fix them. My secret? Total quality control (TQC), statistics, and DOE.

Copper Via-Fill Technology in Development

The use of via-in-pad technology is increasing rapidly in today’s PCB designs. The need for miniaturization, combined with the rapidly decreasing pitch of component footprints, drives printed circuit board designers here. Via-in-pad requires the vias to be filled, planarized and then over-plated with copper.

It's Only Common Sense: Make a Cool Million

It's Only Common Sense: Make a Cool Million What if your new boss offered you $1 million if you could triple your sales in 12 months? That’s right. What if your boss told you that on top of your normal salary and commissions, you could earn a cool million dollars to increase your sales three-fold? What would you do that you're not doing now?

New Material and Process Solutions for the Electronic Interconnection Industry

The manufacture of electronics has, for the last several decades, followed a production script that has changed little over time. The vast majority of printed circuits are still being manufactured and assembled using materials and processes that the pioneers of the early printed circuit industry would easily recognize.

The Quiet Mainstreaming of HDI Manufacturing

Advances in technology continue to push the envelope of what’s possible. And nowhere has the impact of those advances been felt more profoundly than in the evolution of the current class of mobile devices. Although design engineers have driven this evolution, primarily through addressing market demand for new form factor innovation, the push to meet the associated manufacturing challenges has been responsible for a revolution in PCB manufacturing.
