ITM Employs JEDEC-9704A to illustrate How to test a Printed Circuit Board (PCB).
How to run strain gauge and stress test on Printed Circuit Board (PCB) using JEDEC-9704A
Every modern electronic device includes at least one printed circuit board (PCB), so it stands to reason that these intricate parts fail at times due to stress and strain. Our team can share how to test a Printed Circuit Board (PCB).
When that happens, manufacturers know they can turn to ITM’s test engineers who can develop tests to help get to the bottom of their circuit board problems. For some, the failures are happening in the field, and for others, it’s the manufacturing process that’s overstressing the parts that make all our gadgets go.
Contact an expert to learn How to test a Printed Circuit Board (PCB)
Engineer Ryan “RJ” Matthews said ITM has decades of experience with printed circuit boards (PCBs), including circuit board design and development. So, strain gauge testing on PCBs using JEDEC-9704A, the global standard for microelectronics, and employing Hooke’s Law, is a natural progression for the team.
Matthews has led recent projects in which ITM uses a strain gauge rosette to help companies determine how much strain and stress their PCB is experiencing both in the field and during the assembly process. Simulating the assembly process can be a daunting challenge, particularly if that process includes variables such as high heat, as it did in a recent example.
Still, the team was able to instrument the circuit board effectively and replicate every assembly step while also gathering crucial strain data, which they reported back to the client. The challenging test environment isn’t unlike ITM’s typical rugged data acquisition projects, just on a much smaller scale. The firm specializes in strain gauge data collection on everything from behemoth off-road machinery to miniscule gadgetry.
Matthews said the team often employs NI c-DAQ hardware combined with ITM’s proprietary iTestSystem software, which allows them to easily configure PCB tests to collect and analyze the data. iTestSystem’s Rosette Analysis tool is used to calculate the principal strain, principal strain angle, shear strain, principal stress, and other values from strain gauge rosette data.
ITM Using Acosense Tech to Analyze and Measure Industrial Process Fluids
Most of us have been working on being better listeners since elementary school. ITM has entered into the trial phase of an exciting partnership with a Swedish engineering firm that is taking listening to the next level.
The firm is called Acosense, and their breakthrough technology relies on Acospector Acoustic Chemometer, a clamp-on instrument that can measure complex fluids in the process industry, delivering analysis previously thought difficult or impossible to obtain. The innovative technique measures a multitude of properties such as density, viscosity and solid content moving through industrial pipes. The method is non-invasive and can even return results on opaque, viscous or corrosive fluids. Ultimately, the idea is to help reduce production costs, increase product quality and reduce environmental impact.
For ITM, which works extensively with clients in the pulp and paper industry to improve processes and efficiences through various forms of industrial monitoring, the tech holds a great deal of potential and aligns with our expertise in vibration technology. If all goes as early trials indicate, ITM could be headed toward an exclusive distribution agreement in the U.S., said Ryan Welker, Vice President of Integrated Test & Measurement.
Acosense officials said they turned to ITM to target the U.S. market because of the team’s “high vibro-acoustic competence and market knowledge.”
“ITM is really easy to work with given the level of personal skills and hands-on experience from several types of industries,” said Karl Nilsson, Acosense CEO.
Welker said ITM is currently in the middle of a months-long trial using Acosense tech at a global paper company, gathering data on supply lines within the plant, then comparing that data to actual samples collected by the mill’s lab to look for correlations between the chemical makeup and the acoustics profile of various fluids.
“The big thing would be being able to measure these properties without breaking into the process lines,” said Welker. “It could be a very easy and clean way to give our clients continuous feedback. And it is a quick and easy installation.”

ITM Co-op Helps Engineering Student Set Sights Even Higher
Tyler House’s dream career began to come into sharper focus during his spring co-op at Integrated Test & Measurement.
After four months at the Milford, Ohio, firm the University of Cincinnati electrical engineering student headed into his summer feeling both excited by his work experience and inspired to emulate ITM CEO Tim Carlier one day by starting his own company.
“I know I want to do something I love,” said Tyler, who had just returned from a trip to Disney with his girlfriend to celebrate the end of the semester. “I’d like to start my own company someday. I’ve been poking at that idea. Definitely a big dream of mine is having that freedom and doing something that means a lot to me.”
Perhaps the only thing that equals Tyler’s love of engineering is his love of music. He and a few fellow graduates from Clermont Northeastern (CNE) high school started a band called Wishbone, which has started lining up local gigs to cover rock and blues tunes stretching back a half century.
Tyler’s two worlds collided on the last day of his co-op when a couple of engineers from ITM dropped into his band’s “first bonafide show.”
“It was so much fun watching their reaction,” said Tyler, who employs his electrical engineering skills to repair the band’s gear when things inevitably break. “I love that they came.”
Coincidentally, like Wishbone, ITM’s entire leadership team — the CEO, VP of Operations, Lead Programmer and Administrative Director — are all CNE graduates. For Tyler, seeing that level of success from the same small high school as him was only more of a confidence lift.
He loves the entrepreneurial and inventive culture at ITM, where staff members are constantly tackling new challenges. “It’s really just a great place to figure out what you are into,” he said.
Tyler found himself learning a ton about Fusion 360, a cloud-based 3D modeling program, while researching mechanical properties and simulating failure modes on a bolted joint. He said he spent about half his co-op in the office doing things like assembling Data Acquisition (DAQ) boxes and the other half on the road working on-site. Experiences included everything from climbing inside massive paper mills to helping gather data on equipment operating in remote locations all over the country.
“In talking with my friends who have had co-ops, it’s hard to get to work in a place where you feel like you can make a difference and actually help fix problems,” said Tyler. “I definitely felt that. I learned really fast about how to deal with mistakes and just general problem solving.”
Besides the on-the-job learning, he loved exploring new places, national parks and more with the ITM crew after hours. He’s hoping to pick up some work helping ITM with any projects through the summer, and he’s interested in returning during his next co-op rotation in Spring of 2023.
Meanwhile, he’ll keep poking at his dream of someday owning his own company.
“You just have to go out there and get it,” Tyler said. “If you are aggressive about it, you will fail a bunch. But you’ve got to be able to get up off the ground and just keep rolling with it.”
This box reveal may not be quite as dramatic as the ending of “Seven,” the ’95 serial killer thriller that blew moviegoers’ minds, but the ITM team is throwing open the latches nonetheless.
In this case, our team is taking you on a quick tour of a recently deployed Rugged Data Acquisition System. These particular black boxes of tech are riding around on high-dollar fracking equipment to remotely monitor all sorts of triggering events. Our crew builds them on the regular, and the end result is that our clients can better understand what sorts of stress, strain and vibration is taking place both en-route to their site and once operations begin.
ITM is known for building rugged measurement systems and data logging solutions that are deployed on everything from Class A trucks, to well frac trailers, to dam and bridge structures, oil pipelines, gensets, boilers and more.
So, without further ado, what’s in the box?
We recommend a handful of essential components and elements if you are looking to build your own rugged measurement system:
You’ll need industrial grade connectivity, and you can’t beat Peplink’s cellular router options. And remember to outfit that unit with an AT&T or Verizon plan and get that activated card installed.
A remote desktop application is a must, and we usually turn to LogMeIn for our remote access and file management. This allows us to pull up any of our units no matter where they are in the world to check in on status or grab some data for our clients.
Speaking of data, depending on your job, you’ll likely need lots of data storage capability. Our preference is a 2 terabyte USB drive, which gives us an almost unlimited amount of space. If needed, we can store about six months worth of data before hitting capacity.
Since our industrial PC is running Windows, we use iTestSystem, our proprietary engineering measurement software platform that enables test engineers to organize, acquire, view, and analyze data from machinery, processes, vehicles and other complex systems.
To complete the box, our industrial PC is connected to an NI c-DAQ outfitted with strain, vibration and voltage modules.
What about power you ask? In our fracking instance, we connected to an alternator which charges a bank of batteries in the RAC.
So there you have it. That’s what’s in the box. Build your own, or get in touch with our team, and we’ll customize a system for your specific needs.
We also install and service all of our equipment. So if something breaks in the field, we can get you back up and collecting data or even assist with data analysis.
Design Validation Finite Element Analysis (FEA) using strain gauge measurements.
Endless Testing Options Through Finite Element Analysis (FEA)
Whether our customers need us to validate their Finite Element Analysis (FEA) models or perform both the physical testing and the FEA, our engineers are used to helping customers with complex testing and analysis of high-value equipment.
As a recent example, our team is involved in a large-scale project to do engine testing for a client that requires ITM to do both the physical testing as well as the FEA simulations. This requires using a custom high-channel count telemetry system to transmit engine data to a receiver that is sampling at an extremely high rate.
“Once you are able to bring in the test data and compare it to the simulated data, you are able to fine tune your FEA simulation to better reflect the real-world application,” said ITM engineer Ryan Matthews. “We can also simulate the test in software and predict how it is going to react to the test when we can actually measure such things as strain, stress and vibration.”
Matthews points out that FEA technology also helps the team determine the precise best placement of strain gauge during physical testing. And depending on complexity, a single simulation can take a few seconds or months to run.
For obvious reasons — mainly the cost of bringing high-value assets to failure — running repeated strain gauge tests on components simply isn’t feasible, but ITM’s in-house capabilities and close partnership with sister firm SixDOF opens up endless FEA simulation options to clients.
“Sometimes you are only going to be able to test a structure or a part once before it fails,” says Matthews. “So it becomes crucial to do a limited number of physical tests then correlate that to your FEA. Then you can pretty much run unlimited simulations.”
ITM SFD technology helps energy producers generate power more efficiently by detecting energy sapping soot buildup in power and recovery boilers
According to the U.S. Department of Energy, the pulp and paper industry is the 3rd largest consumer of energy in U.S. manufacturing. A great deal of that energy is expended to generate massive amounts of steam inside about 200 black liquor recovery boilers spread around North America. That steam then powers generators that produce electricity to operate the mills.
Imagine the energy savings if enhancements inside those recovery boilers could conserve 5% of all that steam. Not only would this advance in boiler efficiency carry an enormous environmental impact — potentially trillions of BTUs — the value of that steam savings would equal more than a million dollars a year at every plant where it is adopted.
Figures like these help explain why Tim Carlier has spent years refining the novel idea he calls the Sootblower Fouling Detection System or SFD. SFD is his patented technology for measuring fouling/slagging as well as sootblower performance and reliability in recovery, biomass and utility boilers.
In a typical boiler, fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In the case where the fuel is biomass, the flue gas often contains a significant amount of carry-over, which collects on the boiler tubes causing buildup. This buildup, also known as fouling, decreases the efficiency of the heat being transferred to generate steam while also increasing the risk of plugging the boiler and taking it offline altogether.
For decades, these industries have relied on sootblowers — long rotating lances that are inserted through the superheater and other steam-generating tubes during combustion — to blow off soot and dislodge the masses of ash deposits that form around steam-generating tubes. Rather than running sootblowing systems “blind,” the SFD System removes guesswork by pinpointing exactly when and where sootblowing is required.
The system relies on a series of sensors on the sootblowers as well as at key locations on the boiler system that allow it to measure the energy transfer to indicate how much buildup is present so that sootblowing is only applied when needed. The feedback mechanisms can inform the plant operator not just where to run sootblowers, but also if sootblowers are leaking steam or malfunctioning in other ways.
“This technology could have a huge environmental effect,” says Carlier, president and founder of Integrated Test and Measurement, the Milford, Ohio, engineering service and software company. “You are getting that much more efficiency out of your boiler, so not only are you saving money because you are not wasting steam, but you are not having to burn as much fuel to generate as much electricity.”
He estimates that recovery boilers at most pulp and paper mills generate between $20 million and $40 million a year in steam depending on their Maximum Continuous Rating (MCR), and roughly 10% of the steam goes toward soot blowing operations.Carlier estimates that SFD could enable operators to decrease their sootblowing between 25% and 50% leading to a savings between $500,000 and $2 million dollars a year.
In addition to the significant steam savings, SFD will also greatly enhance the reliability of sootblowing operations by answering crucial questions for operators: What’s the condition of the sootblower motor and gearbox? Is the poppet valve stuck open, stuck closed, and leaking, or is it operating correctly? Is the track damaged? Is the sootblower lance bent? Is the sootblower stuck in the boiler? What condition is the sootblower packing? Are there any steam leaks on or near the sootblower? Keeping informed on these important questions ultimately helps avoid costly downtime and even schedule crucial maintenance.
On its own, the removal of sootblowing guesswork will generate a quick return on investment, Carlier says. When all is said and done, power generation facilities can expect to see a return on investment from the SFD System in approximately six months to a year.

ITM Engineer is suspended mid-air to install strain gauges at Garrison Dam.
Suspended in a harness 30 feet above a concrete spillway in central North Dakota, ITM engineer Ryan “RJ” Matthews instruments the gate of one of the world’s largest earthen dams with dozens of strain gauge sensors.
Integrated Test & Measurement’s field service technicians and engineers have installed strain gauges on civil structures and machinery around the globe for decades, and this project represents one more example of rugged data acquisition. In this instance, the team rappelled from an overhead abutment on the Garrison Dam — a 2-mile-long structure along the Missouri River built by the Army Corp. of Engineers starting in 1947.
Contracted by Cotech IRM Services, ITM was charged with collecting data to measure the strain on one of the 28 spillway gates which are designed to raise and close to allow water to pass from the reservoir during rare flood events. Just behind those gates is Lake Sakakawea, one of the largest man-made lakes in the United States.
Garrison Dam Spillway
Despite the complex location, Matthews and co-worker Zach Strong were able to successfully instrument the spillway gate with 44 single-axis strain gauges and solder signal cables which lead back to a NICompactDAQ system connected to their laptop, allowing them to successfully gather streams of crucial data using iTestSystem while the gate was put through its paces.
The project is yet another example of ITM’s ability to combine the use of strain gauge sensors, a cDAQ system and the firm’s iTestSystem software to create a structural health monitoring system. In this instance, the project required only one-time testing, but ITM can also establish a permanent structural health monitoring system as well.
iTestSystem is an engineering measurement software platform that enables test engineers to organize, acquire, view, and analyze data from machinery, processes, vehicles and other complex systems. iTestSystem was specifically designed for use with National Instruments (NI) cDAQ hardware for data collection and data logging.
For Matthews, it was his first experience installing strain gauges while strapped into a bosun’s chair and dangling in midair, but he points out that ITM’s strain gauge process is essentially the same whether their engineers are standing on a bridge or inside a railcar. All that changes is the method of access and environment.
His field notes reveal that each strain gauge on this job was wired in a quarter bridge configuration, which provides one individual measurement of strain (positive tension or negative compression) per location. All gauges were adhered to the gate using M-bond 200 epoxy. A final report submitted to the customer contained detailed instrumentation and test notes and results reported in a series of stress/strain tables and stress graphs.
