Note:

It is essential that water purity used for Damp Heat tests PH level inspected for all Damp Heat tests.

Chemicals commonly found in commercial water supplies such as chlorine can cause unintended corrosive effects and product under test failures.

At Fersht Inc. we use for all Damp Heat tests water with PH levels range as indicated in Electronic and Photonic standards. We inspect PH level range for every test we perform at our facility.

Fersht Inc. facility found that it is essential to run THB test with the right PH water level as stated in MIL-STD-810F.

We follow this rule for every Damp Heat or THB test at our facility.

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

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.
