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 on its surface. Such products...

In the early days of the electronics industry, before SMT (Surface Mount Technology) was fully developed, almost all circuit board assemblies had to go through this type of "wave soldering" process in order to solder electronic parts to the circuit board.The reason why it is called "wave soldering" is that it involves the use of a barrel of tin furnace which is heated to a temperature that melts the tin strip and forms a molten tin liquid.With the advances in industrial technology, most electronic components are getting smaller and smaller and can meet SMT reflow requirements (e.g., small size and...
