Analyzing, locating, and repairing circuits is the basic work of hardware engineers and there will always be all kinds of strange problems. We need to gradually locate and solve the problems one by one to reduce the failure rate, improve the production line yield, and improve the average Trouble-free time and reduce after-sales problems.  This section introduces several common analysis ideas, which are common in hardware circuits such as mobile phones, tablets, and computers. 1.Poor soldering - short circuit. The factory may cause partial tin connection during SMT, and the amount of tin connection is not much....

  Gemology microscopes come with advanced features, though they’re easy to use. Some also include the ability to assign saving folders which helps with organizing images, or features that allow you to annotate images. Ring holders, gemstone and diamond stages, and light boxes are specially designed accessories you can find on some gemology microscopes that help aid in delivering the best imaging results. Below are some of the salient features of a good gemology microscope. Zoom adjustment The location of this feature can be at the top or on the sides of the microscope’s head. It...

Digital Microscope Bomb Is Coming! With long-term reseach and development, our new star - Andonstar AD206S, a great tool for for SMT/SMD/THT/PCB Soldering, finally come on the scene!As an upgraded version of AD206, Andonstar AD206S digital microscope have been improved a lot in terms of function. There's a great noticeble hightlight of this upgradation, namely its double lens and double screen, which aren't covered by AD206.   With double lens and double display, AD206S can be connected with an endoscope and display images of endoscope when the screen is showing the microscope's images. That allows soldering engineers...
