DES Increases Combined Temperature & Vibration Testing Capabilities

DES added another larger AGREE Chamber to perform Combined Temperature and Vibration Testing. This gives DES additional capability to perform combined environmental testing on larger products. DES has performed Combined Temperature and Vibration Testing on car engine sensors, helicopter sensors and outdoor heavy industrial products. Some of the test specifications include MIL-STD-810 and General Motors GMW 3172.

The Equipment Capabilities Are:

Combined shock or sinusoidal, random, mixed mode vibration and temperature
Temperature range from -80°C to +180°C (-112°F to +356°F)
Temperature rate of change up to 20°C/minute
9 cubic feet interior work space, cvo

Recent Testing Projects

We had many interesting test projects at Delserro Engineering Solutions this past month:

We completed a Pyroshock test on our Mechanical Impact Pyroshock Simulator (MIPS) on equipment that will fly into outer space.
On the other end of the altitude spectrum, we completed environmental testing of components that will be used in submarines to MIL-E-917. MIL-E-917 is a military specification for Naval shipboard electric power equipment.
In the middle of the altitude range, we performed combined temperature and vibration testing on sensors that will be used in automobile engines to specification GMW 3172. GMW 3172 is a General Motors Specification for electronic component durability.

The following is a sample of some additional testing projects we have completed recently:

Lead Free Solder Reliability Issues and Test Methods

This article discusses the reliability challenges of switching over to lead-free solder and the test methods used to demonstrate reliability, written by Gary Delserro and published in Evaluation Engineering Magazine. Click on the link to download the article in PDF, Lead Free Solder Reliability Issues & Test Methods.

Environmentally friendly is a term rapidly invading the electronics industry.

The electronic industry will be facing great challenges over the next few years as the solder used in electronic products is migrating toward lead-free. This is being driven by mandates in Europe such as Waste Electrical and Electronic Equipment (WEEE) and Restrictions of Hazardous Substances (RoHS) and similar ones in Japan. There also is a great deal of pressure in the US to do the same.
