ELECTRICAL TESTS:
Electrical testing being one of our original core activity, the CERB company disposes of a wide range of high-performance electrical measuring equipment that can be used for various applications such as :
- Passive component qualifications:
Qualifications of: Inductors, Capacitors, Resistors…
Semi-automatic measurements.
- Reliability and qualification tests:
• Continuous electrical monitoring:
Monitoring of the electrical resistance of various component assemblies during accelerated ageing tests using ANATECH test benches and according to the IPC-9701 standard.
Test measurements conditions:
Record of opens >200ns on 256 channels per test bench (we dispose of 5 ANATECH test benches). Static electrical measurements before and after tests in order to check for possible drifts of the resistance values of tested assemblies.
• SIR tests (Surface Insulation Resistance) :
Electrical monitoring of the insulation resistance of comb patterns or component assemblies under 85°C/85%HR temperature/humidity to evaluate the compatibility of materials/processes like solder paste/cleaning process, solder paste/solder mask …
Test conditions :
Measurements sampled every 20 minutes with a 256-channel test bench internally developped by CERB. Validation of the results after completion of the tests.
• Detection of nano opens on connectors during vibration tests
• ON/OFF power cycling test bench for electronic components.
Setting options of:
ON/OFF dwell time
Number of cycles
Monitoring of times of charge and discharge to validate the compliance to the
manufacturer's specifications.
• Development of specific test benches adapted to customer needs.
