Electronic components must be interconnected to form an electronic circuit with specific functions, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is to weld them to printed circuit boards. Electronic components may be packaged separately (resistors, capacitors, inductors, transistors, diodes, etc.) or groups of different complexity, such as integrated circuits (operational amplifiers, rejection, logic gates, etc.).
Widely used in buttons, chargers, electrical appliances, stationery, lampshades, instrument housing, chassis, furniture, sporting goods, gears, tableware, surface, decorations, glue, small building materials, soles, color plates, hoses, hard pipes, soft boards, hard boards, mechanical accessories, tool housing, lens, automobiles, meters, electronic parts, sockets, power lines, headphone wires, telecommunications, key chains. Toys, plugs, sockets, connectors, USB cables, switches, etc.
