It is mostly used in jewel store to prevent theft and to catch intruders.

These machines are tailored to suit the needs of small PCB assembly areas.The entire assembly is passed through a reflow oven that has an infrared lamp.
The components will be held onto the board by the surface tension of the solder paste.Solder PasteBefore applying the solder paste.Thermal SoakOnce you have brought the board to the required temperature.
It is most commonly used for assembling PCBs in mass production.The temperature of the board is gradually increased before the soldering process to prevent thermal shocks.
some parts of the board will have a lower temperature.
the board is subjected to controlled heat to prevent thermal shock.org/wp-content/uploads/2021/03/best-java-books.
