MLH45 Laser Soldering Head

With the growing demands of miniaturization, the mta® laser soldering head MLH45 offers precise and powerful circular laser microspots. By focusing the laser diodes beam through an optical system, this contactless soldering technique guarantees a uniform solder joint heating and a maximum repeatability.

The laser head has an integrated monitoring camera and a laser pointer which ensures an easy teaching.

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 dispenser in order to guarantee a perfect mastery of the complete process.

For bigger applications, the wire feeder is mounted on a rotatory axis and provides high feeding accuracies, optimal accessibilities and simple adjustments. It includes wire presence checking and feeding control.
