Microflame head

mta’s microflame soldering head is typically selected for robots in two extreme applications. At one extreme, it solders high-mass joints similar to the induction system. At the other extreme, it solders relatively small joints that require a very quick soldering process.

We can integrate the microflame head for soldering robots on any of our standard soldering platforms including: MRC500, TR300 OEM and station.

The main features of our microflame head include:

• Patented pivoting flame tip
• Electrolysis providing gas from distilled water
• Non-contact soldering process
• Jam-free wire feeder mounted directly on the head provides tight process control
• Flame detection and automatic lighting are available as options
• Compatible with RoHS (lead-free) solder

8 reasons to choose the mta microflame soldering head 

1. The patented pivoting flame tip rotates very quickly to precisely control heat exposure.
2. The flame burns around 3000° C, but it is extremely small. It quickly focuses intense heat in small isolated areas to avoid damaging nearby components or plastic housings. In many cases, we use it to solder joints that other soldering technologies would damage. For example, the microflame can solder small diameter wire terminals before the wire insulation has a chance to melt.
3. There are no stamped sheet metal or die-cast parts. We machined the robust head structure from solid material to provide a rigid platform for the iron and wire feeder.
4. The clamping system provides easy adjustment and precise alignment. Once tightened, the position will not change until loosened – there is no risk of accidental misalignment as a result of heavy use or while changing tips.
5. We mounted our precise jam-free wire feeder directly on the head – at the solder joint. This provides tight process control of the wire feed. Solder wire does not kink or get jammed since there is no long feed tube. Once the correct amount is fed, the wire feeder pulls the wire out of the solder pool to prevent solder spatter.
6. We integrated the fume extraction nozzle into the head itself. Therefore, it is mounted directly above the solder joint to safely remove fumes.
7. In addition to the microflame, wire feeder and fume extraction nozzle, the head can support several optional devices such as: cameras, flux dispensers, dual feeders, dual irons and the list goes on.
8. Electrolysis provides gas from distilled water. Consequently, there are very low consumables – no iron tips or cleaning sponges.
