Which Microscope Should You Use to Inspect Metal Surfaces?
10/09/y 14:25:39

A stereo microscope is suitable for visual inspection, 3D surfaces, and applications that require direct manipulation of the specimen. A metallurgical microscope is better suited to flat, prepared metal samples and applications that require high-magnification analysis of microstructures.

Soi PCB nên dùng kính hiển vi phóng đại bao nhiêu lần ?
10/09/y 11:37:29

Kiểm tra PCB bằng kính hiển vi không đơn giản là chọn mức phóng đại càng lớn càng tốt. Khi phóng đại tăng, trường nhìn thu hẹp và vùng quan sát thay đổi. Với công việc sửa chữa, người dùng còn cần khoảng trống đủ lớn để đưa mỏ hàn, nhíp hoặc dụng cụ vào dưới vật kính.

Should You Choose a Binocular or Trinocular Stereo Microscope?
10/09/y 10:47:33

A binocular model is primarily intended for direct observation and hands-on work through two eyepieces. A trinocular model adds an optical port for connecting a camera, allowing users to capture images or record videos for training, documentation, or research.

Signs of bearing wear via rotational speed fluctuations
09/09/y 16:08:34

Worn bearings do not cause an immediate drop in the engine's average speed. What changes first is speed stability slight fluctuations in speed occur from one rotation to the next even though a standard tachometer continues to display a seemingly normal RPM reading. This is precisely what many people overlook. While the average figure looks fine, detecting instantaneous fluctuations reveals that the bearings had actually begun to develop play quite some time earlier
