Abstract
An apparatus for disconnecting solder joints between two welded surfaces includes a laser device for emitting laser beams to a solder joint, and a solder material removal device. And the solder material removal device includes a nozzle device having a first passage, a holder holding the nozzle device and having a second passage communicated with the first passage, and at least two pumping devices connected to the holder to pump the melted solder material out from the nozzle device and the holder. The laser device and the solder material removal device are separated, a glass cover with a hole formed thereon is covered on the top of the holder, and the laser device is located above the glass cover and separated from the holder. The present invention can shorten maintenance time and maintenance workload and improve work efficiency, furthermore reduce and stabilize the laser energy.
