How to Choose the Best PCB Reflow Oven for Efficient PCB Solder Assembly
Whether you’re an electrical engineer or an electronics hobbyist, solder reflow ovens enable fast and convenient printed board (PCB) assembly. If you have assembled dense PCBs with many small surface-mount components or used ball grid array (BGA) devices in your designs, you have undoubtedly come across solder PCB reflow ovens. While the ambitious hobbyist may choose to build a toaster oven “reflow oven” , many businesses can save time and

How to Setup and Interface with WS2812B LEDs for PCB
Are you in the mood for a good laugh? Well, I have a story for you. I’m a design engineer with decades of experience, but a LED project recently almost brought me to my knees in despair. I used to think that LEDs were as simple as getting the light emitting diode connected to a limiting resistor and a power supply. Aren’t they? That’s exactly what went through my mind as I worked on an architecture model lighting project a couple of years ago. On

2018 Olympics: Intel Will Showcase Future PCB Technology in Electronics and Communication
Editorial credit: lazyllama / Shutterstock.com I love watching the Olympics. It’s exciting to see the best athletes from each country test their skills against one another. The Olympics are also a forum for host countries to showcase everything that they’re capable of. In the 2018 Olympics countries aren’t the only ones who will be showing off. Intel recently announced a partnership with the International Olympic Committee (IOC) that will let

How to Perform In-House Pre-Compliance Testing for Radiated Emissions
Sometimes you can feel like you’re putting out good vibes, but you’re really emitting something else. The same goes for wireless circuits. You go through the design and immunity testing, then send your board off to an EMC lab only to find out your board is radiating the electronic equivalent of garlic breath. Performing in-house hardware pre-compliance testing can help you avoid a costly rejection. You’ll have to spend some money on equipment

Conducted Emissions Test Equipment and Noise Reduction Guidelines
One of my classes in college was so difficult that the professor would give us the test questions a week in advance. Even knowing exactly what to study for the exam, lots of students still failed. Conducted emissions analysis for electromagnetic compatibility (EMC) is similar. Devices need to be checked to see if they’re putting too much noise back into the grid through their power supply. Otherwise, the FCC will think you’re disrupting utility

How FRAM Memory Simplifies Embedded System Data Logging
I’ve always found it easier to make decisions when the options were clear-cut. Choosing between black and white, right or wrong, you could make your decision and never regret it. However, decisions that involve picking black, white, or one of many shades of gray really stress me out. I was happy abiding by my binary logic until Ferromagnetic Random Access Memory ( FRAM ) came on the commercial market and I was forced to embrace one of the shades

Massive MIMO Benefits for 5G Cellular Infrastructure
Editorial credit: PureRadiancePhoto / Shutterstock.com Even though I ended up here in southern California, I was originally born in Texas. We have a saying that you probably have heard, “everything’s bigger in Texas.” That turned out to be true for me, as I’m the tallest member of my extended family. I’d like to think that the minds behind massive multiple input multiple output (MIMO) antenna arrays were also born in Texas. MIMO has been around

IoT Storage Technologies: Ultra Low Power CBRAM
Do you remember using those old floppy disks back in the day? I remember my computer had two floppy disk drives. You’d put the disk with your program in one and a disk for the data in the other. Eventually, the incredible invention that is the hard drive came about and storage space exploded. Our memory capacity is still increasing, but now the size is becoming less of a factor. When it comes to the Internet of Things (IoT) energy usage is the

Why Wearable Technology is the Future and How It Will Be Seamless and Convenient
When I was younger I was a bit of a nerd, and I guess I still am. The most visible sign of my nerdiness was my fashion sense or lack of it. Tall socks, cargo shorts, and a brown Pacman hoodie that I wore in every season, except summer, made up my daily wardrobe. I was simply more interested in gizmos and gadgets than I was in looking good. I’m still more interested in fashionable electronic devices than clothes, but the line between the two is

The IoT is Developing New Technologies for Aging in Place
My grandmother has lived down the street from my parents for the past 7 years. She moved down there after it became apparent she had Alzheimer’s disease and my parents realized she couldn’t live alone anymore. However, technology has allowed her to live a semi-independent life. My mother uses nanny cams to make sure my grandma is safe and happy and goes down to the house whenever grandma needs help. This arrangement has kept my grandmother out of

Impressive Next Gen PCB Designer Nicole Pacino
Mike Creeden, Founder of San Diego PCB, with his daughter Nicole Pacino With the median age of today’s PCB being 48 years old, it’s always refreshing and encouraging to see a young sprout up amongst the design community ranks. One such young is Nicole Pacino of San Diego PCB. Nicole is the daughter of Mike Creeden, founder of San Diego PCB, who is also an IPC Master Trainer and IPC ’s Council executive board member. As you can imagine, Nicole was

How to Plan Your PCB Layout for a High Voltage Design
I used to trail run with a friend who is an urban planner. As part of her devious plan to get me to run further before I was too tired and bored, she’d tell me about the various considerations that go into the zoning and construction in a town. There were also a lot of shenanigans with local politics that provided a juicy distraction. Although my friend would disagree, a high voltage PCB layout have some similarities to complex urban planning. In

PLC System vs Embedded System: When You Should Choose a PLC Despite the Higher Cost per Unit
Have you ever gone out to a well-reviewed, luxurious restaurant for dinner? I’m sure you paid a pretty penny for it. However, if fine dining is a passion of yours and you enjoyed it then it’s worth the expense. On the other hand, it’s hard not to feel silly paying $20 more than you’re supposed to for a sandwich at an average local restaurant. In this situation, you’re much better off putting that money towards cooking lessons and becoming your

Digital Player Grounding: How a Single Ground Connection Messed up 100 Units of MP3 Players
Technology is pretty great and it has definitely made certain things in life easier. However, when you’re juggling parenting, coding, electronics design and occasionally writing an article like this. Sometimes even the coolest apps can’t mitigate the stress we experience in a day. For example, this morning I accidentally mistook salt for sugar and mixed it into my child’s favorite porridge. One small mistake on my part and suddenly my 5-year-old
