I would like to thank you again for your fast response, your work and the great service you provided at such a short notice.

I am happy we found your facility and we definitely will need more work very soon.

Oct-2010

Fersht is highly knowledgeable expert in the area of optical component reliability, failure analysis, and failure mitigation. It was immediately obvious to me that he had built up considerable expertise from his work with many industry-leading optical component companies. Not only did we benefit from his testing services, Joseph’s advice and suggestions were also very helpful and saved ........

Nov-2010

I am so happy we found you and run these test that reviled these problems with the foreign supplier.

It saved us embarrassment

Feb-2011

We got the parts back overnight.

Your prompt support helped us to provide the data we needed.

Our customer is happy.

Thanks

We liked the way we could monitor the progress of the test/data

We definitely will need more tests.

Regards

July-2011

You helped us get the test rolling fast.

All our team would like to thank you for the quick response.

October-17-2011

Thank you for your great service on this project.

We got the parts late Saturday night and have completed the testing with good results.

A great relief for me and our project team.

Examples of Accelerated test Requirements:

Accelerated aging (TC)

In addition to the temperature cycles to which optoelectronic devices are required to be subjected as part of the environmental stress tests, it can be useful to expose modules to a number of additional temperature cycles for “accelerated aging” purposes. Unlike the high-temperature accelerated aging tests, the primary purpose of the additional temperature cycles is generally not to cause
Gradual degradation of a particular performance parameter instead, it is to provide an additional demonstration of the long-term
Mechanical stability of the optical alignment within the module package.

Humidity

Although humidity acceleration factor models have been developed for some types of non-hermetic devices, at this time relatively little data exists on such issues as long-term diode degradation and optical coupling instabilities due to humidity.
Therefore, relatively long and severe tests are generally called for in this area, and the results may be primarily of use in the calculation of random failure rates instead of wear-out failure rates.

MECHANICAL SHOCK TOWER

Precise control of the shock amplitude is provided by the PC based controller which utilizes a high performance multifunction analog, digital and timing input/output and data acquisition board with custom software running in a Windows environment. The data storage capacity can be used for careful analyses and to generate impressive test reports.

The Mechanical Shock Tower develops the kinetic energy electro magnetically. An iron core "bullet" is attracted to the magnetic core of the solenoid by the dense magnetic field that is created as current flows through the field coil of the shock tower. As the bullet is drawn into the center of the magnetic field the acceleration increases exponentially as the gap reduces to zero on impact causing the high impact shock. The properties of the impacting materials determine the pulse shape and duration. The RTV strike pads supplied with the system provide half sine pulses of 1.0, 0.5, and 0.3 millisecond durations.

VIBRATION SYSTEM
