Applicable components include SOIC, CHIP, QFP, PLCC, BGA, SMD. On top of that, the station is especially suitable for desoldering in-line sockets, transformers, LCD screens, nixie tube screens, IC chips, and in-line headers. The unit's applications include heat shrinking, drying, paint removal, glue removal, defrosting, pre-heating, glue soldering, and more. Before using the sniffer nozzle, you need to turn the machine on, and the tin gun handle heats up to dissolve the tin of tip and then suck the tin
