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...

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....

A printed circuit board is a panel or plate made up of one or a pair of conductive patterns. They are located on the surface of the dielectric base. In some cases, a system of conducting patterns located on the surface and in the volume of the dielectric base is used. The main purpose of printed circuit boards is to mechanically fasten quantum electronics and electronic technology, as well as to connect them electrically. Varieties of printed circuit boards The simplest option is a plate with copper conductors on one side, connecting the elements of the conductive pattern only...
