Communication electronics industry (including chips)

In the field of communication, we provides product testing technology services for equipment manufacturers and customers, provides strong support for their product development, production and market access, provides base station electromagnetic environment testing and base station electromagnetic radiation testing for operators, and provides technical support for base station site selection and base station environmental protection management and control.

Services include PCB, PCBA, electronic materials (accessories), electronic devices, semiconductor chips.

Failure analysis of board-level process

Printed circuit board (PCB) and its components are the core components of electronic products, and the reliability of PCB and PCBA directly determines the reliability of electronic products. We carry out a comprehensive physical and chemical analysis of the failure to confirm the internal mechanism of the failure, so as to put forward targeted improvement measures.

Test standard:SJ/T 11399、GB/T 4937.1-36

PCB quality evaluation

We can provide end-to-end closed-loop work for the whole process of PCB board test scheme to improvement measures analysis, including PCB interlayer alignment, solder mask alignment, line width accuracy, back drilling depth, impedance test, thermal stress (tin immersion test), withstand voltage test, cold and hot shock, temperature cycling, CAF evaluation, etc.
