Our Group has had its own Verification and
Validation Center for many years, where teams of passionate and highly
qualified professionals in testing and validation engineering, specialized in
different areas of expertise, carry out their activities in sophisticated
laboratories. Starting from the setting up of the DV/PV Design Verification
& Product Validation test plan, to diagnosis and problem solving, and then
Our laboratories are equipped to simulate,
through consolidated methodologies that follow the guidelines of the reference
standards, any operating condition; each product is subjected to a qualification phase during which numerous tests are carried out:
electromagnetic compatibility tests; electrical tests; mechanical tests, both
static and dynamic; environmental and material tests. These are time-consuming
and thorough procedures that produce excellent results.
The execution of qualification tests takes place in different locations of the Group in an autonomous way, a necessary condition to provide customers with the complete know-how from design to validation, as well as clearly improving the time to market.
In the laboratory in Italy we have a wide
and complete range of environmental conditioning systems such as 4 shaker
vibration systems with climatic chambers, 8 climatic chambers, 3 thermal shock chambers,
2 salt spray chambers, 6 thermostatic chambers, advanced instrumentation for
the execution of electrical and electromagnetic compatibility tests (required
by international directives and specific test specifications of automotive
manufacturers) and a metrology room recently equipped with a new automatic CMM
The EMC quality requirements provided for by the regulations in force and by the specifications of the OEM customers are achieved with tests carried out in an anechoic chamber and, with the aid of full compliant instrumentation, tests of radiated and conducted emission according to CISPR25, tests of immunity to radiated electromagnetic field according to ISO 11452-2 and conducted with Bulk Current Injection method according to ISO 11452-4 are carried out.
With the aid of a compact anechoic chamber
and a radio communications tester, products developed by MTA and equipped with
wireless capabilities (Bluetooth and Wi-Fi) are subjected to pre-certification
emission tests and the necessary diagnostic measurements via radio (OTA - Over
Tests of immunity to electrical transients on power and signal lines, in accordance with ISO 7637 and customer specifications, are performed on test benches fully equipped for this purpose.
The impact of ESD electrostatic discharge on devices is evaluated with immunity tests performed in accordance with ISO 10605 and variants introduced by the specific requirements of automotive manufacturers.
A specific test environment and a precision spectroradiometer allow the analysis of the photometric characteristics of dashboards and displays.
The new lab in MTA Morocco is equipped to
do all electrical, mechanical and environmental testing for the power
distribution units assembled on site and supplied directly to customers.
The instrumentation in Morocco is larger than that in Codogno to cope with the fact that the PDUs are increasingly important in size, more powerful, heavier and must be tested in greater numbers because of the higher levels of reliability required today.
Worth mentioning are the 2 600 l and 1000 l climatic chambers, a 1200 l salt spray test chamber, a thermal shock chamber, a 600 l chamber for vibrating system, a vibrating system with 22 kN slip table.
In MTA Brasil, the laboratory, which has
been set up for several years now, has been updated during the many
interventions carried out in 2020.
It is equipped with two climatic chambers from -70°C to +150°C; a 600-liter salt spray test chamber; a 350-liter chamber for thermal shocks from -70°C to -180°C, as well as numerous electrical and electronic equipment.
The laboratory in China was set up as soon
as the entire business moved to its current site. Since 2017, in a dedicated
area, the main tests are carried out, such as those on dimensional, electrical,
mechanical, environmental aspects, mainly aimed at quality tests of connectors
The laboratory is also equipped to cope with an expected increase in the product range that will be supplied from China to some important OEMs and that needs the guarantee of all the tests required by the customer.
In fact there are 2 environmental simulation systems: a climatic chamber compatible with the implementation of a vibrating system and a controlled ventilation oven; a SmartScope for dimensional measurements; a dynamometer; a nanovoltmeter; a digital oscilloscope; a melt flow tester.
The laboratory in Slovakia, developed over
the years in parallel with the growth of the site, ensures the control and
continuous testing of production processes in particular of plastic molding and
the necessary support for the periodic requalification of the product as well
as the activity of problem solving.
It is equipped with basic equipment for the main mechanical and leak tests and a metrology room with optical measurement systems and profile projectors for dimensional measurements.
