A soldering system for processing at least one printed circuit board. The system comprises a first solder pot and a second solder pot, each configured to move within a movement plane. At least one of the first solder pot and the second solder pot is further configured to rotate about a solder pot axis extending transverse to the movement plane. The first solder pot and the second solder pot can be moved relative to the at least one printed circuit board, and at least one of the first solder pot and the second solder pot can be rotated about its solder pot axis relative to the at least one printed circuit board, to simultaneously process the at least one printed circuit board using both solder pots. The soldering system may thus be used to process either a single printed circuit board with both solder pots simultaneously or a pair of printed circuit boards simultaneously with each solder pot processing one of the pair of printed circuit boards. A corresponding soldering method is also disclosed.

A wave soldering station includes a solder pot having a reservoir of solder material, a flow duct positioned in the reservoir of the solder pot, and a wave soldering nozzle assembly coupled to the flow duct. The wave soldering nozzle assembly has a solder distribution baffle configured to create a solder wave, a throttle gate coupled to the flow duct and configured to move from an open position to enable complete flow of solder through the solder distribution baffle and a closed position to inhibit a portion of flow of solder through the solder distribution baffle, and an exit wing coupled to the flow duct and configured to move from a lowered position to enable increased solder flow and a raised position to decrease solder flow. A controller is configured to control the movement of the throttle gate and the exit wing to control the flow of solder.

The present application provides a position detection apparatus, comprising a bottom plate, an abutting member, a trigger member, a trigger member, and a distance sensor. The abutting member is movably disposed on the bottom plate. The trigger member is connected to the abutting member. The induction member is disposed on the trigger member. The distance sensor is disposed on the bottom plate. The induction member and the distance sensor are disposed such that: the distance sensor is capable of detecting a movement distance of the induction member when the abutting member drives the induction member to move, and wherein the trigger member bypasses the distance sensor. The position detection apparatus of the present application has a higher detection accuracy of relative movement of the induction member to the distance sensor.

A solder supplying method for maintaining the Bi content contained in a solder alloy in a solder bath at a predetermined amount even after soldering a large number of printed circuit boards with a Bi-containing solder alloy. A solder supplying method includes supplying an additionally supplied solder, which is Sn and/or a low-Bi solder alloy having a lower Bi content than a Bi-containing solder alloy, to a solder bath into which the Bi-containing solder alloy has been introduced, thereby adjusting the Bi content in the solder bath to the Bi content of the Bi-containing solder alloy when it has been initially introduced in the solder bath.
