MLH45 laser head

The mta MLH45 laser soldering head is used in a variety of applications: joints that are too small for the iron i.e. <1mm, the part is delicate and requires a non-contact heat source, or the joints are in tight places that physical heating units cannot reach. For the smallest applications, and especially in case the wire size is too large to reach optimal results, the head can be combined with a solder paste jet dispenser in order to guarantee a perfect mastery of the complete process.

The MLH45 laser head can be integrated on our standard specific soldering platforms including: laser MRC500 and TR300 on which the laser system is guarded with metal sides and mechanical door to protect operators from the laser.

The main features of our MLH45 laser head include:

  • Uniform solder joint heating
  • Easy teaching with integrated monitoring and laserpointer
  • Diode laser with optical fiber
  • Non-contact soldering
  • Jam-free wire feeder is mounted directly on the head to provide tight process control
  • Lead free compatible

3 reasons to choose the mta MLH45 laser soldering head

  1. Can be combined with solder paste jetting system.
  2. Dedicated to very small solder joints.
  3. No accessibility problems due to non-contact soldering process.
