Our goal is to achieve the highest level of reliability for your products, under all operating conditions
Micro Systems implemented a quality-control system in 1996, leading to ISO 9001 certification.
This path, involving continuous improvement and growth, allowed us to achieve the highest levels of reliability for our electronics by incorporating tests, procedures and other measures which all reflect great attention to detail.
ELECTROMAGNETIC COMPATIBILITY TESTING
Electromagnetic disturbances are one of the main causes for unreliable electronics. Unexpected resetting, loss of data, measurement errors, UI malfunctions and failure of IC components are all possible damage caused by electromagnetic disturbances. The repercussions on the operations of the machine controlled by the affected electronics can be serious, with serious consequences for the end customer. We made the choice to create electronics which are first and foremost totally reliable under all operating conditions, even in the presence of strong electromagnetic disturbances, whether these come from the exterior or are generated inside the machine itself. For this reason we chose to equip ourselves with all the equipment required for electromagnetic compatibility testing, in order to have direct control over this crucial phase for obtaining highly reliable electronics.

SELECTING THE BEST ELECTRONIC COMPONENTS
In order to ensure that the components we use meet the high quality standards we have set for ourselves, they undergo a type-approval procedure. The type approval of new components consists of a complete series of laboratory tests and close monitoring of their behaviour in the field for at least a year.
STORING COMPONENTS AT CONTROLLED HUMIDITY LEVELS
Storing SMD electronic components in normal warehouses, where the levels of relative humidity are not controlled, can irreversibly compromise their long-term reliability.
The water molecules can penetrate the components, and then by expanding following the soldering process can cause malfunctions even well into the future.
In order to avoid this and ensure high levels of reliability, SMD components which are liable to absorb moisture are kept in a special storage system which completely eliminates atmospheric humidity.
DUAL PRODUCT OPERATING TESTS
This important procedure is performed on all electronic boards we manufacture, not just samples.
Functional testing is performed on all products via the use of automatic workstations which are able to minimise human error.
As well as testing their operation, the electronic boards are left running for a sufficient number of hours to test all critical components.
For further information, see: Testing
The application of a protective coating which protects the surface of the circuit board from dust, corrosive agents or atmospheric humidity.
Without such protection, the combination of dust and moisture could create unwanted connections between the PCB tracks and electronic components, leading to inevitable malfunctions.
THERMAL TESTS IN A CLIMATE CHAMBER
The climate chamber tests the behaviour of the electronics as the temperature and the humidity they are exposed to are varied.
The test can be performed over a range of temperatures from -20 to + 70°C, with humidity ranging from 10 to 90%.
INFRA-RED CAMERA THERMAL TESTING
The operating temperature of the board’s various components influences their average lifetime. Excessively high temperatures can significantly reduce the lifespan of the components and compromise their general reliability. Thermal analysis highlights the system components with the highest operating temperatures. Subsequent analysis of the board’s design checks that these temperatures are within the design operating range.
