Mechanical Shock testing of the devices X-Y axis determines the suitability of the devices for use in electronic equipment which may be subjected to moderately severe shocks as a result of suddenly applied forces or abrupt changes in motion produced by rough handling, transportation, or field operation. Shocks of this type may disturb operating characteristics or cause damage similar to that resulting from excessive vibration. Devices are tested to MIL-STS-202, Method 213B and are typically subjected to three saw tooth pulses with an amplitude of100 g’s for five to six milliseconds in each axis direction. After testing, the devices are visually and electrically tested after testing to look for failures.

Powered burn-in testing screens for and eliminates marginal devices, those with inherent defects or defects resulting from manufacturing weaknesses which cause time and stress dependent failures. Burn-in profiles are chosen to verify the capability of the product to perform under load and to eliminate infant or latent failures.

Swept Sine Vibration testing determines the effect of high-frequency vibration on component parts in the frequency range of 10 to 2000 Hz as may be encountered in aircraft, missiles and tanks, etc. This test does not strike random frequency vibrations, but sweeps across the frequency spectrum as prescribed by specific test parameters. Compliant to MIL-STD-202, Method 204, devices are mounted into a custom fixture and placed on the vibration shaker. When the test is completed, the devices are visually and electrically tested to look for failures.

This test performed in accordance with MIL-STD-202, Method 208 and resistance to solder heat per MIL-STD-202, Method 210,Test Condition C. The terminals are exposed to a solder bath of 350ºF, at an immersion angle of 90º. The devices are then held in the solder bath for a period of five (5) to ten (10) seconds. The solder is applied to either ¼ inch from the nearest insulating material of the component or ½ of the exposed length of the terminal (which ever is closer). This test verifies that pre-assembly lead finish provides a solderable surface and sufficient quality to make an acceptable solder joint. By passing, it proves that the device can withstand the heat applied during the solder operation.

The purpose of stabilization bake is to determine the effect on the device storage at elevated temperatures without electrical stress applied. Devices are placed into the Blue-M, Model CC-041-P-B-HP Environmental Chamber and subjected to 24 hours of dwell time at +150OC per MIL-STD-883, method 1008, Condition C.

This test proves the resistance of a device to extreme high and low temperatures. Fre-tech uses Blue-M Thermal Shock ovens, Model WAP-109-D with full data capture. Tests are compliant to MIL-STD-202, method 107. Typical tests can be 1000 cycles of temperature shock for a total of 100 hours with a low temperature of -650ºC and a high of +150ºC with each cycle held for 15 minutes between the extremes with a transfer time of 15 minutes. When this testing is complete, devices are removed and electrically tested to search out any failures.
