The physical properties of the cables and related components are tested in the test room for comprehensive performance, including tensile strength, structural dimension, density, and plating thickness, etc. The X-ray tester in the test room for comprehensive performance can measure the plating thickness of the metal stuecture of the printed circuit boards (PCBs) and components according to the X-ray spectroscopy method adopted by ISO 3497, ASTM B568-98 and GB/T 16921. The fully automatic image tester can accurately measure the size of devices with complex structures, greatly improving the accuracy of the measuring dimensions or thickness parameters per IEC 60512-1-2, IEC 60811-20x series, EIA-364-18, etc.
Test programs in Zhaolong's test room for comprehensive performance seem to be simple, but the data analysis are highly demanded. The uncertainty analysis of the dimension or thickness measuring results in the test room for comprehensive performance are strictly conducted in accordance with the requirements of ISO Guide 98 series and JJF 1059 series standards, and then a rigorous declaration of conformity will be given.
