Winning With Fewer PCBs
The business world keeps score with dollars and cents. The overhead cost of layout and material cost of bare boards are a significant drain on capital. Face it; Printed Circuit Boards are expensive.
This is a Story About Tape-Out Day
All of the little details were squared up when the check-plots came out for "final" review. Those same preliminary files were shared with the fab and assembly units and, of course, the vendors have c
Sustaining Engineering - What to do After You Hit a Homerun
Success! Oh, the sweet, sweet problems of success. The first problem is that we just cannot build these (insert product) fast enough. The second is that suddenly there is a new cash cow in the room. T
Making the Most of a Design Win
It is a wonderful time to be a maker of products. Find an underserved niche and give the world a tangible solution. Famous movie quote, “If you build it, they will come.” The hard part becomes finding
Grab A Coffee And Let Optimizer In PSpice Do The Work For You! (Part 2 of 4)
Anyone who designs complex circuits and claims they don’t use the Optimizer in their circuit design is most likely a super-genius with an IQ of 250. Optimizer is a common feature used by many designer
What is the Cost of Field Failures?
We see it in the news frequently; a battery explodes, car brakes malfunction, electronic systems are hacked, a material inexplicably fails. Field failures are costly and unforgiving, necessitating...
PSpice Optimizer enables you to quickly and accurately tune your circuits to meet your unique design requirements.
PSpice Monte Carlo Analysis
Monte Carlo predicts the behavior of a circuit statistically when part values are varied within their tolerance range.
The sun rises every day. It is reliable. In practical terms, it has always risen and will continue to do so. On a long enough timeline, however, our star will burn out. That's what the...
Notes from the Board Room - on Checklists
Not just one, there should be a sanity check at every major step in the life of a layout. Some of us fondly remember the Apollo program on the grainy black-and-white TVs of the day. The whole...
So, You Want to be a CAD PCB Layout-er
Knowledge workers are of the variety that knows and does something that their manager probably doesn't. Even the schematic capture experts struggle with the layout software. It has always been a...
How Do Manufacturing Tolerances Work?
In July 2017, a rollercoaster ride in Ohio failed dramatically, killing one person and injuring seven others. The cause of the accident? Corrosion. Roller coasters must operate and withstand...
Notes from the Board Room - A day in the life of a Googler
In my quest to become a world famous PCB designer, (stop laughing!) I've taken to putting my own words on the screen and sharing them here. My job is to enable design wins, period. It's a cruel...
Oh Say Can You C? – Grappling with the USB type-C Connector
I can honestly say that I was working on the USB-C protocol before USB-C was cool. Google was/is part of the specification development consortium. My first encounter was in early 2015 trying to...
The Cost of Not Simulating
Most products go through a pretty thorough QA and testing period, but this testing is often done over weeks or months. This leads to the question, “how can testing of physical products detect...
How (and Why) to Embrace Design Constraints
Design rules are nothing new. Our ability to create specific and concrete rules to govern the results should not be overlooked. From the first placement study to the final result, capturing a...
