Modelithics launches standard and custom test fixture and accessory product lines

Modelithics, the world's leading supplier of RF & microwave simulation models has acquired the ProbePoints substrate fixture assets formerly provided by J Micro Technology.

The acquisition includes test fixtures and probing accessory products for the RF/microwave and electrical test of advanced semiconductor devices and packaging products. This includes the popular ProbePoint alumina substrate fixtures that allow devices without ground-signal-ground probe pads to be tested with RF wafer probes. Modelithics will also leverage its twenty years experience with fixturing and calibration for high accuracy measurements to offer other standard and custom microwave and millimeter-wave test fixtures and calibration standards alongside the legacy J Micro ProbePoint fixture products.

Designers will now be able to obtain test fixture and accessory needs supported through a company known for precision measurements and trusted models for the past two decades. Modelithics has established an excellent reputation in the RF/Microwave industry through its characterisation and measurements services, as well as the measurement-based active and passive simulation models, such as the Modelithics COMPLETE Library which is available for use in multiple popular EDA simulation tools.

“The key to Modelithics long-term success is that our team knows how to consistently get excellent measurement data that become the basis for our high accuracy models. Since our founding, we have been making custom fixtures and in-fixture calibration standards, as well as using Jmicro fixtures, where applicable. With the launch of this new test fixture product line, we are now prepared to help others who want to make their own measurements with better fixtures and on-board calibration standards.”

Larry Dunleavy - President and CEO of Modelithics

Test fixtures and test accessory products

The newest offering of test fixtures and test accessory products includes legacy parts from J Micro Technology for a family of thin-film alumina substrate components to adapt the benefits of coplanar waveguide wafer probe test methods to the measurement of devices suited for connection to microstrip circuits. Along with this offering, Modelithics is also providing custom coaxial and RF probe test fixtures suited for a wide range of substrate and test interface environments.

These components enhance productivity in product development and product assurance testing for semiconductors and packages. Some versions are available with series resistors to provide bias current stability. Calibration structures substrate and companion printed calibration kits are available for various adapter substrate configurations.
