FORCED-FEED PRESSURE CONTROL DEVICE AND FORCED-FEED PRESSURE CONTROL METHOD

摘要

A forced-feed pressure control device according to an embodiment includes a pressure detection nozzle, a pressure detector, and a controller. One end of the pressure detection nozzle is inserted into a casing member from which molten solder is forcibly fed to a solder jet nozzle of a jet-flow soldering device. The pressure detector is connected to another end of the pressure detection nozzle to detect a pressure of molten solder forcibly input from the one end into the pressure detection nozzle by using gas that exists between the molten solder inside the pressure detection nozzle and the pressure detector. The controller adjusts a forced-feed pressure of the molten solder to the solder jet nozzle so that the pressure of the molten solder to be detected by the pressure detector becomes a reference pressure.
