Vibration test chambers

When further combined with functional electrical testing you can be sure that products leaving the factory are to the highest standard. Specific application for printed circuit boards provides an effective method for detecting poor solder joints as well as manufacturing errors prior to delivery. Typical ESS test profiles have temperature ramping rates of 5K/10K/15K per minute. Large amounts of circulating air improve the thermal transfer and ensure that the specimens are homogeneously stressed. Test chambers vary in size from 600 litres up to 2200 litres. The precise height of the system can be altered to accommodate most shaker types. During testing the specimens are protected by a separate independent temperature sensor. The water in the system is automatically replenished without interruption to the operation. The vapour-tight welded, stainless steel test enclosure with integral shelf support gives the test chamber a high level of stability during shaker operation. This design also makes the inside of the test space easy to clean. The machine unit with large cooling units is located below the test chamber in a maintenance friendly position. The control and power unit is located in a switch cabinet at the back of the test chamber. Every electronic circuit has it's own safety mechanism which switches off the relevant function circuit and/or the entire test chamber when faults occur.
