PCB Layout: Preparation is 75 Percent of the Job


Reading time ( words)

Recently I was remodeling a bathroom in my home with my younger son Kyle. We were getting ready to paint the bathroom and I took out the masking tape and began instructing my son on the task of masking. Being a teen, and of course knowing everything, he said to me that he did not need to mask and he could just start painting. I then explained that I did not want paint on everything else, and if you are a parent, you know how the rest of the conversation progressed.

The voice of my father popped into my head during the conversation and I told my son something that my father always said to me, “preparation is 75 percent of the job.” My father was a military man, and a stickler on discipline. Not the physical spanking kind, although I did get those on occasion, but the kind of discipline to live your life by.

Our younger generation today tends to lack the discipline of preparation. In a world where almost everything is available instantly at a touch of a button, there is often an expectation of instant gratification.

But, in PCB layout, preparation is a key discipline to the success of your design. Preparation truly is 75 percent of the job! We must setup constraints or rules to guide us from the beginning of the layout to the final release of the design and all the way to fabrication. When this preparation is done correctly, we have the best chance of getting it right the first time.

In my recent article in Printed Circuit Design & Fab , “Using Constraints to Make PCB Layout Easier,” I speak about setting up constraints early in your design cycle to prepare for a successful design.

As for that painting project…my son began painting without masking. He got paint everywhere, and spent quite a bit of time cleaning up the mess and re-painting. I had him read my article, and I could tell a light came on in his mind. I expect next time he will prepare properly before starting a task.

Until next time,

Vern

I recently spoke with Al Neves, founder and CTO of Wild River Technology, about the release of their new ISI-56 loss modeling platform. Al explains why it was so critical that this tool meets the stringent requirements of the IEEE P370 specification (which he helped develop), and why he believes this is currently the best tool for SerDes testing and characterization.

This week, we have quite a potpourri for you. There's good news about the PCB market. And as this year continues to surprise us at every turn, companies are discovering the true nature of their leaders. Todd Kolmodin has a great column about bosses and leaders and why the two words are not synonymous. Not to be outdone, columnist Barry Olney found a way to explain the wavelength of electromagnetic energy by using a chocolate bar and a microwave oven. We also have great articles by Sagi Reuven and Pete Starkey.
