About PSI

Pasadena Scientific has been supporting the thermal transient testing industry for over 50 years. We design and manufacture precision thermal transient test equipment used to evaluate semiconductors, electro-explosive devices (EEDs), airbags, bridgewire devices, and other electronic components where reliability and performance are critical.

Our thermal transient test systems are used in both laboratory and production environments and are built with a focus on accuracy, repeatability, and long-term reliability. Over the years, Pasadena Scientific equipment has been used across a wide range of aerospace, defense, electronics, automotive airbag, and manufacturing applications.

Pasadena Scientific’s current flagship platform is the PSI 730 Thermal Transient Test Set, a fully integrated thermal transient testing system designed to simplify testing while improving measurement accuracy, repeatability, and throughput. The PSI 730 combines precision pulse generation, waveform capture, analysis, automation, and data logging into a single modern platform.

Pasadena Scientific has remained focused exclusively on thermal transient testing for over five decades. That long-term specialization has allowed us to develop deep expertise in thermal transient measurement techniques, bridgewire testing, semiconductor testing, airbag initiator testing, electro-explosive device (EED) testing, and high-reliability production test applications.

Pasadena Scientific is headquartered in Maryland, USA.

What is Thermal Transient Testing?

Thermal transient testing is a measurement technique used to evaluate the thermal and electrical characteristics of electronic devices and bridgewire-based components by applying a controlled electrical pulse and analyzing the resulting response over time.

The technique is commonly used for:

 

  • semiconductor evaluation

  • airbag initiator testing

  • electro-explosive device (EED) testing

  • bridgewire analysis

  • weld verification

  • production screening

  • reliability testing


Thermal transient testing can help identify manufacturing defects, inconsistencies, damaged welds, poor thermal coupling, and other conditions that may impact device performance or reliability.
