SMD installation
Surface mounting is called SMT (Surface Mount Technology).
SMD is a Surface Mount Device, that is, a component or device mounted on a surface. Sometimes SMD elements are called chip components, for example, a capacitor chip or a resistor chip.
The whole point of SMT technology is to install electronic components on the surface of the circuit board.
Compared to the technology of mounting components into holes (called THT - Throuth Hole Technology), this technology has many advantages.
Production of semiconductor case SMD LEDs for lighting and decorative lighting
High quality materials for production from European suppliers
Air cleaning and ventilation system for organization without dusty production
Automated machines and other industrial equipment
Antistatic floor with graphite impurities
The procedure for cleaning the working form in a special air shower with dust-collecting flooring
