Optimizing PCB Testing with the Latest 3-Element Stacked Rosette Strain Gauge Technology

Optimizing PCB Testing with the Latest 3-Element Stacked Rosette Strain Gauge Technology

As the demand for thinner, smaller, and more densely populated PCBs increases, Micro-Measurements' new G1350A perfectly fits the bill for evaluating PCBs' stress. Thanks to the flex circuit and pre-attached lead wires, it features a compact design and significantly simplifies the installation process.

A stacked rosette strain gauge is a particular strain gauge designed to measure the typical strains along different directions at a single point. A regular strain gauge measures the deformation or strain of a material in one direction. In contrast, a rosette strain gauge, composed of multiple strain gauges, can measure strain in multiple directions. A stacked rosette strain gauge consists of several individual strain gauges stacked on each other, each oriented in a different direction to measure the strains in various directions at a single point. The stacked rosette configuration allows for a more compact design compared to a planar rosette, where the gauges are arranged next to each other.

Usage on Printed Circuit Boards (PCBs):
  • Quality Control: During the manufacturing of PCBs, there may be internal stresses generated due to various processes such as lamination, soldering, etc. These stresses may lead to the PCB's warping, bending, or even cracking. Stacked rosette strain gauges can measure these internal strains at critical points on the PCB to ensure they are within the permissible limits.
  • Design Validation: During the design phase of PCBs, engineers use finite element analysis to model and predict the strains and stresses that the PCB will be subjected to during its operation. By attaching stacked rosette strain gauges to the prototype PCBs and subjecting them to real-world operating conditions, engineers can measure the actual strains experienced by the PCB and compare them with the predicted values from the model, helping in validating the design and making any necessary modifications before mass production.
  • Failure Analysis: When a PCB fails during operation, it is essential to understand the cause of the failure to make necessary design modifications and prevent similar failures in the future. Stacked rosette strain gauges can be attached to the PCB at locations suspected of experiencing high stresses or strains. By subjecting the PCB to the operating conditions that led to the failure, engineers can measure the strains at these critical points and determine if they were the cause of the failure.
  • Thermal Expansion Measurement: PCBs often have components that generate heat during operation, which can cause thermal expansion of the material. This thermal expansion can lead to mechanical stresses and strains on the PCB and its components. Stacked rosette strain gauges can measure these strains accurately and help design PCBs that can withstand these thermal expansions without failure.

Micro-Measurements' G1350A Features:

  • Round shaped to facilitate spot installation.
  • Minimal form factor of 5.1mm diameter.
  • Readily available resistance values: 120 ohm (C4A) + 350 ohm (C4K).

Load Cells: The Vital Component in Precision Weighing

Load Cells: The Vital Component in Precision Weighing

A load cell is a transducer or a sensor that converts force into an electrical signal. In industrial weighing applications, it's a critical and core component used to measure weight or force.

The most commonly used types of load cells in industrial applications are strain gauge load cells, which work on the principle of piezoresistance. When a load or force is applied to the strain gauge, it deforms or changes shape. This change in shape causes a measurable change in the electrical resistance. The change in resistance is proportional to the load applied, meaning the more significant the load, the larger the change in resistance.

This change in resistance is usually minimal, so it's converted into an electrical signal using a Wheatstone bridge configuration. The signal is then amplified and converted into a digital form by an analog-to-digital converter. This digital signal can be interpreted and displayed on a readout device, such as a digital display or a computer.

In industrial weighing applications, load cells are ubiquitous, with applications including weighing scales, industrial scales, batching scales, and load-testing machines. They can measure loads ranging from tiny (a few grams) to large (hundreds of tons).

Load cells are robust and reliable, capable of withstanding harsh industrial environments. They can handle extreme temperatures, high levels of vibration, and other challenging conditions. Additionally, they offer high precision and accuracy, which are critical in many industrial applications.

In addition to their use in weighing, load cells measure tension, compression, and shear forces, making them versatile tools in many industrial processes. They play a significant role in quality, inventory, and process control in various industries, including manufacturing, agriculture, food processing, pulp & paper, power generation, transportation, and construction.

BLH Nobel is a leading weighing and force measurement solution provider, including load cells, weighing modules, and process control equipment. The company is renowned for delivering precision, reliability, and durability, particularly in harsh industrial environments.

KIS Weigh Modules, adeptly deployed on dynamic process vessels amidst harsh, sanitation-intensive areas, have mastered the art of thriving amidst grime and grit. Their performance remains uncompromised and exceptional, even in the most challenging conditions riddled with corrosive acids, potent industrial cleaning agents, acidic vapors, and abrasive granulated powders.

Part of the remarkable performance of the BLH Nobel KIS is its ingenious cylindrical design. KIS beams can be maneuvered within the module's infrastructure, aligning precisely with the direction of the applied weight. The modules feature cylindrical, electro-polished stainless steel, forming an almost friction-free surface, allowing the module yoke to glide effortlessly during thermal expansion and contraction periods.

Stress Analysis With the Use of Strain Gages

Stress Analysis With the Use of Strain Gages

When external loads are applied, stress analysis assesses the internal forces and stresses acting on a material or structure. Strain gages, widely used in this process, measure the deformation (or strain) that occurs when a material experiences stress. The following provides a detailed explanation of how to accomplish stress analysis using strain gages:


  1. Selecting strain gages: The first step involves choosing an appropriate strain gage for the specific application. Consider factors such as the type of strain (e.g., tensile, compressive, shear), the expected magnitude and direction of strain, temperature range, and material properties of the test specimen.
  2. Preparing the surface: Before attaching the strain gauge, clean and thoroughly prepare the test specimen's surface, using solvents, abrasives, or other cleaning methods to remove contaminants, ensuring proper strain gage adhesion to the surface.
  3. Installing strain gages: Bond the strain gage to the test specimen using a specialized adhesive. Align the gage carefully toward the expected stress, accurately positioning the gage grid (which contains the sensing elements) over the area of interest. Once the adhesive cures, the strain gage installation is complete.
  4. Wiring and instrumentation: Connect the strain gage to a data acquisition system using lead wires. This system usually includes a signal conditioner, which amplifies the small electrical output from the strain gage, and an analog-to-digital converter, converting the analog signal into digital data for further analysis.
  5. Calibrating: Calibrate the strain gage and data acquisition system before starting the stress analysis. Apply known loads or strains to the test specimen and record the corresponding output from the strain gage. Create a calibration curve relating the measured strain to the electrical output of the gage.
  6. Applying loads and collecting data: With the strain gage installed and calibrated, subject the test specimen to the desired external loads. As the sample deforms under load, the strain gage also deforms, causing a change in its electrical resistance. This change in resistance is proportional to the strain experienced by the material and can be measured and recorded by the data acquisition system.
  7. Analyzing data: Analyze the collected data to determine the stress experienced by the material. Typically, this involves comparing the measured strain to the material's known stress-strain relationship (e.g., elastic modulus). Depending on the complexity of the loading conditions, finite element analysis (FEA) or other computational methods may be employed to simulate the stress distribution within the specimen.
  8. Interpreting and concluding: Use the stress analysis results to evaluate the material's performance and assess the design's suitability for the intended application, including identifying potential failure points, assessing fatigue life, or optimizing the design to reduce stress concentrations.


In summary, stress analysis using strain gages requires selecting, installing, calibrating, applying external loads, collecting data, and analyzing the stress-strain data to understand the material's response to the applied loads.

The Role of Feed Screws in The Plastics Melt Stream Process

The Role of Feed Screws in The Plastics Melt Stream Process

Feed screws, also known as extruder screws, play a crucial role in the melt stream process of the plastics industry. The melt stream process transforms raw plastic materials into a continuous, homogenized, and viscous molten mass, which can be further shaped and processed into various products like films, sheets, pipes, profiles, and more. The feed screw is an essential component of the extruder machine, the primary equipment used in the melt stream process.


The role of the feed screw in the melt stream process is explained in detail by understanding its different sections and their functions:


  1. Solid conveying (feed) zone: The feed screw consists of a helical channel or flights with a rotating shaft that runs along its length. The screw begins with a hopper where raw plastic material, usually pellets or granules, is loaded. The rotation of the screw transports the raw material forward, creating a solid conveying zone. The screw geometry in this zone efficiently moves the plastic material toward the subsequent zones.
  2. Compression (transition) zone: The depth of the screw channel decreases gradually in this zone, causing the plastic material to compress. This compression generates heat through friction, which melts the plastic along with external heating elements. At the same time, the screw design ensures proper mixing and homogenization of the plastic materials.
  3. Melting (metering) zone: This zone is characterized by a constant channel depth, where the plastic material becomes fully molten. The screw's geometry creates a uniform and consistent melt flow while providing sufficient back pressure to ensure the homogenization of the molten plastic. Additional mixing elements may be incorporated into the screw design to enhance mixing and homogenization further.
  4. Discharge (melt) zone: In this final zone, the screw conveys the molten plastic towards the extruder die, designed to shape the material into the desired product form. A screen pack and breaker plate are typically placed before the die to filter out contaminants and ensure a uniform melt flow.


Feed screws play a vital role in the overall efficiency and quality of the melt stream process. The design of the screw and its various geometries can significantly affect the processing conditions, output rate, and final product quality. Different types of feed screws are available, tailored to the specific requirements of the plastic materials and end products, such as single-screw, twin-screw, and multi-screw extruders. These screws may also be classified based on their compression ratio, screw profile, and mixing elements.

Understanding Load Cell Overload

Load Cell Overload

When you're talking about load cells in process weighing, what does safe and ultimate overload mean, and how strong are load cells?


The ultimate strength relates to the function as a load cell and not the mechanical strength. The mechanical strength of the load cell is even higher. 


For a load cell, there is generally three capacity limits:  


The nominal capacity of one 100%: Let's say we have a 100-pound load cell. This is the limit or capacity of the load cell. Note the load cell should not be subjected to higher forces under regular use. If the application needs to measure higher loads, then a larger load cell should be used.


The safe load usually is 200 percent of the rated capacity: Let's say with the 100-pound load cell this would be 200 pounds. If the load cell is occasionally subjected to more than 100 percent but less than 200 percent, nothing happens to it, and it will work. If repeatedly subjected to more than 100%, the load cell can be damaged due to fatigue.


The ultimate load is usually 300 percent of rated capacity or 300 pounds for a 100-pound load cell. If the load cell is occasionally subjected to a load greater than 200 percent but less than 300 percent, the load cell will be subjected to a zero shift. However, in most cases, the load cell can be recalibrated and repaired. If subjected to more than 300 percent, the bonding of the strain gauges will most likely be damaged beyond repair. The function of the load cell is damaged, and it should be scrapped. 


As a reminder, this refers to the function as a load cell and not the mechanical part. The mechanical strength of a load cell varies but is often in the range of 400 to 1 000 percent. It should also be noted that there's a fatigue limit for a load cell that generally is 133 of capacity. 



Choose Druck for Supply Chain Confidence

Choose Druck for Supply Chain Confidence

Since the pandemic, supply chain disruptions have posed a significant threat to the global economy. Factory closures and lockdowns in China and several other nations, labor shortages, strong demand for commodities, logistics network disruptions, and capacity limits have resulted in significant delivery times. Manufacturers have had to make tough choices, even relinquishing agency approvals on whole product lines.

Druck maintains regular lead times on pressure instruments and has shortened lead times from 4 weeks down to 3 to meet manufacturers' demands, particularly those facing supply chain disruptions. 

According to a poll done by the National Association of Manufacturers, 36% of companies suffer supply chain disruptions, with items arriving late or not at all. Druck works closely with its supply chain to maintain a 3-4 week delivery on the UNIK 5000 series. 

As firms look for alternative suppliers, Druck demonstrates their dependability as a domestic pressure instrument supplier, serving critical industries.

The Dynisco LMI5500 Series Melt Flow Indexer

Dynisco LMI5500

Of all the tests used by the plastics industry, melt flow rate testing (or melt flow index) is the most widely used. It is traditionally associated with testing polyethylene materials to determine the lot-to-lot consistency of resin lots or batches for quality control purposes. It is, however, also used for other purposes such as testing new materials, determination of material stability versus residence time within plastics processing equipment, or the assessment of regrind content within materials or moldings. It is generally a low shear rate test; however, larger weights can increase the shear rate.

A flow rate test measures a polymer’s mass flow rate (grams extruded in 10 minutes) using an orifice under specified conditions of temperature and load. Machines that determine flow rate are generally called Melt Indexers or Extrusion Plastometers. Test methods by ISO, DIN, ASTM, and others specify heat chamber and piston tip diameter such that the shear stress on the polymer is the same in all machines for a given load. In addition, material specification guidelines (by ISO, DIN, ASTM, GM, etc.) may exist, providing further constraints on how a particular material processes.

Specifically designed for the thermoplastics resin industry, the Dynisco LMI5500 Series Melt Flow Indexer has an array of features and benefits that range from ground-breaking accuracy to a unified software platform between all laboratory and online production equipment.

Cost Effective, Speedy Force Calibration System from BLH Nobel


A BLH Nobel customer's manufacturing process included multiple critical tanks that required regular weight calibration. The largest, a reactor, weighs 60 tons. Traditionally, they calibrated the vessels by filling them with water, a laborious and expensive process. It took a week for each tank.  Aside from filling the tanks, each must be emptied and rinsed. Finally, calibration required thorough drying before resuming production. 

BLH Nobel developed a method to elevate the vessels and read the weight change at various stages of the process. This video demonstrates that method.

BLH Nobel's solution allows the calibration of a weighing vessel, silo, or tank in a fraction of the time compared to using flowmeter or weighbridge calibration. BLH Nobel jacks the tank using hydraulics instead of loading with weights or flowmeter. Typically they measure the result in several points and verify the weighing result. BLH Nobel's method is often carried out without modifying the existing frame or structure, as most already have a suitable jacking point at each load cell.

In-Line Color Measurement in the Molten Polymer

In-Line Color Measurement in the Molten Polymer

Color measurement is a widely used technology for ensuring the quality of color values during the manufacturing process. Typically, these measurements happen offline. The time it takes between sampling and receiving results from the laboratory can be lengthy. A significant disadvantage is that only one measurement occurs during this period, and the color quality during, before, and after the sampling point is unknown. A complete analysis is possible because inline color measurements are performed directly in the melt, but when color variations occur, immediate intervention is possible.

Inline color measurement will provide product-quality indicators for immediate and automatic adjustment of process parameters. The outcome is to maintain the highest possible product quality without waiting for sample analysis from the plant's laboratory.

Equitech International Corp. has been in business since 1995, supplying fiber-optic spectroscopic instruments for process analysis to pharmaceutical, chemical, and food manufacturers. In 2005 they entered the plastics market and began extending their technology into inline color monitoring and real-time closed-loop process control. They published a helpful Technical Paper titled In-Line Color Measurement in the Molten Polymer. You can download that paper here.
