Technologies, mounting types, and features
Mounting types
- Wave soldering
- Reflow soldering
- Press-in technology
The specifications and possible applications of these methods are explained in more detail below. The direct plug-in method must be used if you wish to connect connectors to the PCB without using a mounting method.

Contact systems
In addition, the contact system plays an import role with regard to contact resistance and insertion/withdrawal cycles.

Ex approvals
The requirements placed on electrical equipment for use in areas with a danger of gas explosions are described in the IEC/EN 60079 series of standards.
