A solder pot comprising a soldering nozzle and a de-bridging gas outlet is further disclosed. The de-bridging gas outlet is arranged relative to the soldering nozzle such that de-bridging gas is directed between a plurality of soldered parts after they exit a solder outlet.

Provided are a jet solder bath and a jet soldering apparatus using the jet solder bath. The jet solder bath contains first and second jet nozzles which inject molten solder by first and second pumps and a bridge member arranged between the first and second jet nozzles. The bridge member includes a guide portion that guides at least one of flows of the molten solder injected from the first jet nozzle and flowing on the downstream side of the first jet nozzle and of the molten solder injected from the second jet nozzle and flowing on an upstream side of the second jet nozzle, and side members which controls the flow of the molten solder, the side members being arranged near opposite ends of the guide portion across a direction that is perpendicular to the carrying direction of the substrate.

A soldering system includes a temperature measurement device that measures a temperature distribution of a surface of a substrate. The soldering system also includes a driver that drives the soldering system based on a control parameter obtained from the temperature distribution measured by the temperature measurement device.

The invention relates to a soldering nozzle for the simultaneous selective wave soldering of at least two spaced-apart rows of solder joints in a soldering installation, with a base portion which can be arranged on a nozzle plate, and with a wave portion which forms the solder wave during operation and which has a peripheral wall having a free upper side, and with at least one separating strip which can be inserted into the wave portion and which can be wetted with solder, wherein the at least one separating strip is formed as a frameless separating strip.
