It has been a crazy year with lots of ups and downs. But within the clouds, we’ve seen plenty of silver linings, too. Case in point: Avishtech, a brand-new company lead by founder and CEO Keshav Amla. (You may be familiar with his father, Tarun Amla, a veteran PCB materials technologist who is now with ITEQ.) We recently caught up with Keshav and asked him to discuss his company’s simulation tools, his plans for the company, and what it’s like launching a company in this “new normal.”

Andy Shaughnessy: Keshav, you recently founded Avishtech. Give us some background on yourself and tell us how you got into this industry... More >

How do you calculate finished copper on a PCB? This may sound simple. But we have seen copper thickness called out either on the drawing or the specification, which can lead to additional engineering questions (EQs) and, in some cases, additional costs. These are unintentional results as a misunderstanding of what is requested—not in all cases, but some. Let’s start with some terminology.

Ounces relates to the weight of copper that covers one square foot (Figure 1). The area of the board itself cannot change; it’s fixed... More >

Joe Fjelstad has been an innovator in flexible and rigid-flex technology for four decades. About 10 years ago, I-Connect007 helped Joe produce an online workshop on flex technology based largely on his book Flexible Circuit Technology, which was first published in 1994 and is now heading into its fifth edition. In this online video course, Joe offers a primer on flexible circuits, covering everything from the history of this technology through the most cutting-edge technologies.

Now, Joe is updating this workshop to make it current with today’s flex technologies and processes... More >
