An electronic unit includes at least one component and a printed circuit board, wherein the at least one component has at least one terminal. The printed circuit board has at least one first contact surface and at least one second contact surface, wherein the at least one first contact surface and the at least one second contact surface are spaced apart from one another. The at least one terminal is joined to the at least two contact surfaces by at least one solder joint. A method for testing at least one state of an electronic unit is also disclosed.

Electronic unit and method for testing at least one state of an electronic unit

An automation field device comprises a first, a second, and a third connection pin; and a field device electronics designed to be operated either in a two-conductor mode or in a three-conductor mode. The field device electronics have an energy supply unit designed to provide internal energy supply exclusively by means of the fed current in the two-conductor mode. In the three-conductor mode, an additional auxiliary current is to be fed to the field device electronics via an additional single-wire line connected to the third connection pin, and the energy supply unit is also designed to provide the internal energy supply via the fed current and the fed additional auxiliary current. Furthermore, the field device electronics are designed to use the additionally fed auxiliary current for internal energy supply only if the current fed by means of the two-wire line is not sufficient for the internal energy supply.

The invention relates to a method for mechanical connecting especially of a potting frame to a printed circuit board of an electrical/electronic module. The potting frame includes a metal contact area. The printed circuit board includes a surface area structured metallically corresponding to the contact area. The method includes positioning the mechanical component with the contact area facing the corresponding surface area, and soldering the mechanical component to the printed circuit board via the contact area and the surface area. The method the advantage that a material saving encapsulation can be provided for electrical/electronic modules in explosion endangered regions. An additional process step for mechanical connecting of the encapsulation to the printed circuit board can be omitted, since the mechanical connecting of the potting frame can be performed in one process step together with the soldering of the additional electrical/electronic components to the printed circuit board.

The present disclosure relates to an explosion resistant electronic module having a high-speed interface and a method for electronic contacting of such electronic module via such interface. The electronic module includes an electronic component, an electrical contact area for electrical contacting the electronic component and an encapsulation, which encapsulates at least the electrical contact area. The encapsulation is embodied such that the contact area is contactable through the encapsulation by an electrical contact pin, wherein the encapsulation is filled at least in a portion with a self-healing gelatinous potting compound, which enables the encapsulation to be re-sealed after removal of the contact pin.

A circuit configuration for monitoring and/or for regulating supply voltages. The circuit enables at least two supply voltages (U) or (U) that are produced by means of two feed-ins (Q, Q) and that are provided for consumer circuits (V, V) to be monitored and limited simultaneously. To this end, the circuit configuration comprises a corresponding voltage monitoring electronics unit which detects the supply voltages (U, U) and compares them with associated tolerance values (&#x394;U, &#x394;U). The voltage monitoring electronics unit also provides a control signal (y) which signals whether the first supply voltage (U) is lower than the associated tolerance value (&#x394;U). The control signal (y) is used to control a shunt electronics unit through which a shunt current (I) passes temporarily. Said shunt current (I) is fed by feed-in (Q) and by feed-in (Q) and passes through the shunt electronics unit at least when the control signal (y) signals that at least the supply voltage (U) is greater than the associated tolerance value (&#x394;U).
