The soldering iron is a common electronic tool used for soldering and repairing various electronic devices such as electronic components and circuit boards. Before using a soldering iron, there are some important precautions and steps to follow to ensure the job is done safely and effectively, which will hopefully help you better understand how to use it properly.   The electric soldering iron mainly consists of the following parts:  Soldering Tip: This is the front-most part of the soldering iron and is usually made of copper. The soldering iron tip is heated and used to...

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....
