With electronic devices getting smaller and much more expensive, it means there’s a new challenge for us. From laptops to smart phones to game consoles, components are getting smaller.  These small components usually consist of resistors, capacitors, inductors, connectors, microchips, etc. Because these components are too small, we call it Microsoldering, means soldering microscopic materials. Micro-soldering is necessary to fix these tiny problems that cause large issues. For the these tiny components in mobile phones and computers, including iPhones, iPads, Macs, PCs, and Android Devices, special equipment is used to diagnose and repair these PCB's and its common we have...

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....

First of all, make sure your microscope can work with external devices. Among all Andonstar products, models that work with both PC and an HDMI monitor are ADSM201, ADSM301, ADSM302, AD409, AD246S-M, AD249S-M, AD246S-P, AD249S-P.   To work your digital microscope with a computer We collected feedback from many end users, the most common issue they met is their computer couldn’t detect the device change after plugging the microscope to the PC. If you've met the same issue, please check if the connections are as follow: Please be aware that： the dimmer cable is only to...
