MRC500 soldering robotic cell

The mta MRC500 soldering platform for robotic soldering from above is a free-standing machine cell. Our design engineers purposes-built the MRC500 for soldering applications then standardized the design. We built our own platform so we would not need to compromise functionality based on the limitations of third-party equipment. Standardizing the design offers three primary advantages: it is well-proven, available faster and costs less than-off custom designs.

Although the design is standard, it is highly flexible. We designed the mechanical structure to work with a wide range of process equipment, material handling and guarding systems. In its basic configuration, the MRC500 is a free-standing, semi-automated machine. At the other extreme, we can outfit it with SMEMA conveyors, collaborative robots, rotary tables and many other systems. Likewise, our software engineers included flexible modules in our MotionEditor software to quickly integrate a wide range of standard and special options.

We can equip the MRC500 with any of our soldering heads: soldering iron, induction, or microflame. In the case of the MLH45 laser head, we equip the MRC500 specific to laser soldering with laser-safe guarding.

As properly designed heads are fairly heavy, the MRC500 is equipped with large DC stepper motors to provide sufficient strength to actuate the head quickly. The X, Y, and Z axis use robust ball-screw actuators for precise actuation. Repeatability of 20 microns assures the solder process is accurate and delivers consistent quality.

The main features of our MRC500 platform include: welded frame construction, 3-axis Cartesian robot with optional rotary axis at the head, 500x500mm working area, industrial PC controller with Embedded Windows® operating system and intuitive menu-driven mta MotionEditor software.

Available heads

  • Classic soldering iron

    mta’s classic iron head for soldering robots is our most popular soldering technology. Probably because most customers are upgrading from hand soldering with the iron.

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

    The main features of our classic iron head for soldering robots include:

    • Multiple adjustments allowing easy configuration for specific applications
    • Robust structure guaranteeing that tip and wire feeder do not get misaligned accidentally
    • Soldering tips have a long life span and users can change them quickly and easily
    • Extensive tip selection to suit a wide variety of applications
    • Jam-free wire feeder mounted directly on the head provides tight process control
    • Lead free compatible

    7 reasons to choose the mta classic soldering iron

    1. The soldering tip is separate from the heating element, so users do not need to change the heating element as frequently as the tip. This reduces consumable cost.
    2. A pneumatically-dampened spring lowers the tip to allow compliance between the tip and part. This provides good thermal transfer while protecting the parts and tip. Also, the robot does not use the z-axis to move the iron tip.
    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 iron, 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.

  • Induction head

    mta’s induction head is appropriate for robots soldering joints that have a high thermal mass and require more heat to solder. Other heating methods must allow time for the heat to migrate from outside-in; whereas, the induction system is able to create heat within the part to greatly reduce process time.

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

    The main features of our induction head include:

    • Quickly heats parts with high thermal mass
    • We can shape the coil to meet specific application requirements
    • Solid-state control
    • Non-contact soldering
    • The jam-free wire feeder mounted directly on the head provides tight process control
    • Suitable for brazing (hard alloy)
    • Non-conductive parts of the components to be soldered are not heated by the induction
    • Lead-free compatible

    8 reasons to choose the mta induction soldering head

    1. Inductive soldering quickly heats high-mass parts. Therefore, it is an excellent technology for heavy/multi-layer boards, large cable terminals, non-electronic parts, and many others.
    2. Inductive fields heats without damaging the product. Inductive fields penetrate the material to create heat form inside the board. This uniform heating method does not burn the outer surface. By contrast, technologies that push heat from the outside-inward, can damage the outer surface before the joint reaches reflow temperature.
    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 inductor, 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. Very low consumables – no iron tips or cleaning sponges.

  • 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.
