Today, we will present a detailed test report for the XTL65XTL-165 zoom stereo microscope, which features a zoom ratio of 1:6.5. This versatile tool is widely utilized in industries such as machinery and electronics, industrial detection, instrumentation, and jewelry detection, among others. The microscope's working range is from 0 to 150 mm.

Additionally, we employed a Digital Caliper, a device with a digital display that accurately measures an object's dimensions. This tool is essential for checking the thickness of workpieces or the depth of mortises.

The tests conducted were in accordance with the GJB 548B-2005 standard, which outlines the environmental, mechanical, and electrical test methods and procedures for military microelectronic devices. This standard ensures the quality and reliability of microelectronic devices intended for military and space applications.

The specific device tested was manufactured by Intel, with the part number 5M240ZT100I5N. The date code is 2319, and the package type is TQFP-100. The ambient temperature during testing was 23.3 °C, and the relative humidity was 63 %RH.

The full label inspection revealed that the silk screen on the chip's surface was clear and complete, with no signs of secondary coating, grinding, chips, or damage. The pins were also found to be normal.

In terms of dimensions, the measured parameters aligned with the nominal range specified in the original specifications. The package size measurements were also within the expected range.
