Custom Resistor Dividers from Exxelia Ohmcraft Help Enable Innovative Downhole X-ray Inspections

ROCHESTER, N.Y., September 22, 2020 — In order to safely and successfully abandon and cap off oil wells, downhole X-ray technology is used to check the wells for any structural damage or radioactive materials. Exxelia Ohmcraft—a leader in thick-film, high-voltage, high-precision resistor design and ...


...and manufacturing—was recently tapped to develop a custom, high-voltage resistor divider for this application

For more than 15 years, Exxelia Ohmcraft has provided custom resistors for petrotechnical analysis equipment used in downhole drilling. That’s why manufacturers of the downhole X-ray inspection platform turned to Ohmcraft to help develop a custom solution for use in this new and innovative diagnostic tool, which has already generated significant demand in the market.

While cameras are able to capture images of a well’s exterior, downhole drilling X-ray platforms enable oil companies to clearly examine the inside of the well despite harsh conditions, including exposure to high temperatures, high pressures, and fluids. The X-ray inspection helps to ensure the well’s integrity and mitigate any risks.

“The process of taking X-rays deep down inside of a well involves very powerful and specialized equipment, for which the design required reliable high-voltage resistor dividers in a small form factor—a combination that manufacturers struggled to find,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Given our experience in downhole drilling applications and the development of custom resistor solutions, we were able to work closely with the engineers to meets their needs and help them bring this technology to life for their customers.”

Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

Exxelia Ohmcraft High Voltage Chip Dividers Enable Design Flexibility for Manufacturers of Semiconductor Equipment

 Exxelia Ohmcraft High Voltage Chip Dividers Enable Design Flexibility for Manufacturers of Semiconductor Equipment   ROCHESTER, N.Y., September 17, 2021—Microchips—also known as semiconductors—are critical to the function of everyday technologies like mobile phones, computers, radios, and televisions. To finetune the outputs of their main power supply, manufacturers of semiconductor production equipment have leveraged custom resistors from Exxelia Ohmcraft for more than 25 years for their high precision, high voltage and stability.   Exxelia Ohmcraft’s custom surface mount resistors and dividers offer semiconductor equipment engineers with maximum design flexibility in the smallest footprint, as they have the ability to specify both the resistance value of a surface mount divider and the divider ratio. This allows engineers to produce the necessary voltage and current required to create the highest-quality end products.   “Traditionally, high-voltage dividers are made using two different resistors, but our high voltage chip dividers integrate them into one part,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “We always work closely with our customers to ensure that we meet the specific design requirements necessary to create their quality technologies.”   Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.   # # #   About Exxelia Ohmcraft Exxelia Ohmcraft’s thick-film, surface mount resistors are engineered to meet application-specific needs.
