Optimizing Electronic Product Documentation for Assembly and Manufacturing
I’m the kind of person that can get overwhelmed with too much information. If my wife gives me a choice of restaurants to pick from when we go out to dinner, it feels like my head might explode. Burgers, pizza, tacos, chicken, deli sandwich, family-style, Lo Mein, seafood, steaks… my usual response is to look at her and say; “what were my choices again?” She has learned over the years to instead say; “I’m hungry, do you want a burger or some Lo

How to Find Equivalent ICs in Your PCB
When I was younger, I would routinely open up old or broken electronics just to see how they worked. I didn’t start to understand how they worked until I was older, but I always marvelled at the mass of components and the complexity with which they were laid out on a circuit board. I would even have fun connecting from different devices in the hopes that I could resurrect a broken device. ICs in your PCB have a number of specifications that must

PCB Manufacturing Tolerances: Adding Fabrication Tolerance Options to Your Manufacturer Deliverables
Much as we would like, no manufacturing process is perfect. Every process produces slight errors in part sizes or placement, and PCBs are no different. Since some PCB applications have very tight tolerances, you’ll need to specify your tolerance requirements for your manufacturer. Let alone maintaining secure understandings of solder mask and solder placement, material thickness specifications, or any surface mount components - designating your

How Integrated PCB Design Software Helps you Manage Documentation and Outputs
If you’re like me, then you’re a hardware fanatic. You’re the type that enjoys creating and watching your ideas come to life before your eyes. The last thing you want to do is sit behind a desk and create change orders, bills of materials, and assembly plans for your new product. What if there was a way to cut down the time required to generate these important documents? With deliverables and documentation requiring standardized formats and

SMART System for Data Management
I have seen it, and perhaps you have too, where excessive design problems and too many re-spins of a PCB design can be attributed to just one thing; improper data management. I worked with a company once that considered half a dozen board spins acceptable just to iron out all the library problems. These kinds of problems can be greatly reduced and even eliminated with careful data management. The SMART system spells out a data management process

What is SRAM? PCB Design Tips and How to Prevent Data Loss
SRAM loses its data when power is removed. One of the best inventions in editing software is the autosave feature, which prevents Murphy’s Law from striking at the worst time. Decades ago, I nearly cried when several pages of an important university assignment were literally wiped out, as the non-existence of the autosave feature was made worse by my reluctance to hit the ‘Save’ button. In electronics, you risk losing the entire data stored in a

How to Design With a DP83848C Ethernet PHY
In my university days, high-speed internet was non-existent. Online gaming was often limited to Starcraft or Warcraft, played over the Local Area Network (LAN). Friends would gather and start battling each other from different computers within a house, with cries of victories reverberating through the walls. It’s possible to be an awful Warcraft player and still design great PCBs. However, if you fail to understand the LAN and its underlying

Take Charge of Your PCB Design with This Bill of Material Software Free Trial
New Year’s resolutions are often the focus of humor as people admit that they are difficult to keep. The old joke is; “last year I resolved to lose 15 pounds, only 20 more to go.” The important thing about resolutions though is that they show that you are taking charge of something in your life. Diet, exercise, learning, or whatever, the point is that you have seen something that needs to change and you are committing yourself to make it happen

Looking Forward What to Expect After Switching from OrCAD
In my collection of tools out in the garage, I have a pair of tin snips far older than I am. I inherited this defective tool from my father, and it may be 80 years old for all I know. These tin snips are difficult to use because they’ve become dull and loose due to their age, but it was hard for me to make a change because they belonged to my dad. The tin snips frustrated me, so I would find ways to work around them. Finally, after being fed up

Pipelining Your Design File Process with Manufacturing Output Files
An effective PCB design process requires that every step be mapped out and connected together so that the data flows through the design naturally. This type of data management is also known as “pipelining,” and its intention is to guarantee that the design data moves systematically from step to step without any interruption. With advances in today’s PCB design tools the first part of pipelining PCB design data, the component selection process has

Technological Development Made Easy as Pie with Historical Altium Designer
Some words constantly pop-up in daily conversation. Think about how often the word “easy” is used, whether in a bumper sticker that says, “Easy Does It” or a childhood favorite, Easy Bake Ovens. We tell people to “take it easy” and refer to New Orleans as the “Big Easy.” I’m reasonably certain that a guide or book somewhere out there proclaims the “12 Easy Steps to Becoming a Nuclear Scientist.” In a 1940s film called “The Long Voyage Home,” a

DDR Layout Tips to Maximize Signal Integrity of Complex Memory Devices
The science of transporting people by air has changed dramatically in a very brief period of time. During the 1920s, the Ford Trimotor was considered the ultimate luxury flight experience. Affectionately known as the “Tin Goose,” the first all-metal, multi-engine airliner could comfortably carry 10 passengers on a 36-hour transcontinental flight. When we consider modern passenger aircraft, the concept of moving people comfortably over long

Keep Track of Your Components with Electronic Component Database Software
Believe it or not, everyone eventually finds themselves in a situation where they can’t find something they need. You make a list of things you need to get from the grocery store, only to find that your favorite brand is out of stock. Thankfully, grocery stores give you plenty of options right there on the shelves, but you can run into long production delays if this happens when you go to manufacture your next PCB. Sourcing electronic components

How Integrated Tools Ease Multi-board PCB Systems Design
If you’ve ever taken apart a computer, then you know that the entire system can’t fit on a single PCB. The most complicated devices used in a variety of applications are multi-board systems, and designing these systems takes imagination, planning, and the right design software. Rigid-flex PCBs are just another type of multi circuit board system, and the same design concepts when designing each portion of the board, as well as the flex ribbon that

Design Guidelines for Your Next Wireless PCB
As a child, I used to watch Star Trek and always marveled at all the technology. Anything wireless on the show was particularly fascinating, especially to a 5-year old. As I aged, and as so many cool things from science fiction became reality, I realized that all these capabilities start with great PCB design. Whether you’re building a better Wifi router, GPS system, or two-way radio, you’ll need to decide which type of antenna to use and how to

How Autorouters Help Expedite Traces Design
Routing traces around on your PCB is like knitting a quilt. Not only can it take forever, but it requires very precise steps to ensure that all your stitches fit together seemlessly. If you get your stitches wrong, then everything can fall apart. Just like we have automatic threading sewing machines that increase productivity, autorouters can do the same for your PCB. But be wary: not all autorouters have the same capabilities. The best PCB

Electronic Component Distributors Harnessing the Power of One-Stop Shopping
Every year, I spend time working on my house and car to keep them maintained. Trips to the hardware store include adding parts to my stash at home and I try to keep the trips to a minimum so I can enjoy my downtime. There’s nothing worse than chilling to tunes in my garage on a warm summer day only to find that I don’t have a part. Dropping everything to make a run to the hardware store means completely disrupting my afternoon. So managing my
