Differences of Via in Pad Technology in Flex Circuits vs Rigid PCBs

Written by Paul Tome
Posted on March 5, 2019 at 10:52 AM

Many of today’s rigid-flex circuit designs utilize the same high-density components found in rigid PCB designs. This requires the use of blind and or buried vias to allow the signal lines to be routed out from within the high-density components or the high-density areas of the design. The most common component that we see driving this today is the 0.4mm pitch BGA package.

Look around at your desk, work station, or wherever you’re siting while reading this blog post. The odds are favorable there are multiple cables within reach right now!  It’s true, everyone needs and uses cables. Not just in one’s personal life, but also in the workplace, in industry, and even in combat.

What is a PCB Netlist and Why do You Need It?

Written by Al Wright
Posted on January 16, 2019 at 8:40 AM

Nobody wants to experience the feeling of populating your new printed circuit board (PCB) design and finding out that it is not electrically functional. Most often, the lack of functionality is attributable to a specific production problem or a combination of several different problems. Sometimes, however, the problem is that the Gerber files exported from your PCB CAD program contained an error that went unnoticed because there was no way to verify that the files matched your design intent. You can avoid a good deal of trouble by supplying an IPC-356 format netlist file with your fabrication data package.

Differential Paired Cables And When To Use Them

Written by Steven J Goodman
Posted on January 10, 2019 at 2:28 PM

In the world of electronics, oftentimes how a signal is being transmitted from a sender to a receiver is just as important as what is being transmitted in the first place. Certain applications call for incredibly high levels of reliability and resistance to outside electrical interference, so more "traditional" or "common" cables just won't do.

As costs of materials, freight, and labor rise it has become imperative to seek out alternative ways to save costs in the manufacturing process. With traditional means of saving no longer as viable, we now must be more creative and specific when we’re asked, “what can I do to lower the cost of my printed circuit board (PCB)?”

Firmware Development Basics For SMART HMIs

Written by Steven J Goodman
Posted on July 9, 2018 at 1:36 PM

When our customers are in the preliminary stages of launching a new SMART HMI project, they typically reach out seeking advice on the best way to start. With what can amount to a near infinite number of HMI design options and system feature combinations, brainstorming an embedded firmware project can quickly become overwhelming. Where does one begin? How does the firmware work? What level of detail is required now?

“The power of the Internet of Things comes from the ability to collect a lot of data and convert that into useful information.” -Bertil Thorvaldson, ABB Robotics

While that is a very simple concept to understand, manufacturing Internet of Things (IoT) technology into most products can be a significant investment of time and money for companies. As a designer and manufacturer of medical, commercial, industrial, and military products, we are working with many customers on implementing IoT into their products to improve the customer experience and provide an additional revenue stream.

How To Design PCBs - Engineering Advice on Details

Written by Jim Marsh
Posted on June 19, 2018 at 2:04 PM

In front-end engineering, we must gather as much manufacturing information as possible from the printed circuit board data we receive. This includes customer service notes, customer emails, and the general spec, if available. Usually there is enough information to release a printed circuit board (PCB) package to manufacturing. However, I have found many gray areas that haunt our engineering department.

PCB Vias - Everything You Need To Know

Written by Al Wright
Posted on June 11, 2018 at 10:00 AM

As today’s printed circuit boards (PCBs) become smaller, they use fewer and fewer through hole components. It is increasingly difficult to justify allocating precious space for relatively large plated through component holes and their accompanying lands. Instead, it is necessary to use surface mounted components wherever possible. As surface mount technology becomes increasingly prevalent, the majority of the plated through holes on most modern PCB designs end up being vias.
