Standard AdvancedMC modules pass ruggedized tests

In applications such as railway and transport technology, traffic engineering, mechanical engineering and security and defence technology, the definitions of the MicroTCA specification are insufficient for the higher demands of these fields. Consequently a PICMG working group has been active since 2007 in creating solutions that meet these higher demands of the so-called ruggedized sector, with particular emphasis given to shock and vibration resistance and to efficient cooling. The first mechanical tests have now been carried out by Schroff using AdvancedMC modules.

The mechanical design proposed by Schroff for the MicroTCA.1 specification fulfils the higher mechanical demands of the ruggedized sector. The tests that have been performed focus primarily on shock and vibration resistance to IEC 61587-1, level DL3, as described in chapter 10 of the specification. In one defined test of resistance to vibration, Standard MicroTCA guide rails and Standard AdvancedMC modules by Schroff had weights built into them of up to 525 grammes. These were then subjected to the prescribed vibrations and accelerations. Without any additional steps being taken, the ordinary Standard AdvancedMC modules and guide rails from Schroff passed the test. This means that these AdvancedMC modules, with their standard interlocking, are also suitable for use in raw industrial environments (the ruggedized sector).
