Solder paste dispensing heads
Solder paste dispensers for laser and induction
The soldering market is heading towards smaller and smaller applications. Therefore, the size of the solder wire and the influence of its contact with the components become a limit for the achievable process accuracy.
In order to ensure the excellence of its laser and induction processes with the smallest parts, Unitechnologies now has the capability to integrate solder paste jet dispenser or traditional solder paste dispenser. This is integrated directly next to the soldering head, and within the same equipment.
The proximity between the solder paste dispenser and the soldering process ensures a perfect mastering of the complete process. Moreover, due to the complete integration of both process steps within the same automated equipment, the investment costs can be optimized.
3 reasons to choose the solder paste jet dispenser
- No accessibility problems due to non-contact solder paste dispensing process.
- Dedicated to very small dispensed solder paste quantity.
- No solder wire positioning or adjustment.
2 reasons to choose the traditional solder paste dispenser
- Used for medium up to large quantities of solder paste.
- Optimized cycle time and more effective process through combined solder paste dispensing and soldering operation.

MRC500 laser robotic cell
Learn more Read moreThe laser MRC500 is the larger robotic cell that supports point to point laser soldering from above. The standardized platform has a flexible and modular concept that can be adapted to a range of processes from fully-automated in-line to stand-alone semi-automated processes.
The frame of the laser MRC500 is designed to ensure the safety of the operator during the laser soldering process. Furthermore, it also provides maximum accessibility to the working area. The laser robotic cell is only equipped with mta MLH45 laser head.
The main features of our laser MRC500 include:
- Welded frame construction
- 3-axis Cartesian robot
- 500x500mm working area
- Industrial PC controller with Embedded Windows® operating system
- Intuitive menu-driven mta MotionEditor software
4 reasons to choose the mta MRC500 laser soldering cell
- The laser MRC500 is both purposes-built and standardized. The advantage of being purpose-built is that there was no need to compromise functionality around pre-defined limitations. The advantage of standardizing the design is that it does not come with the heavy cost associated with one-off custom machines.
- The X, Y, and Z axis use ball-screw actuators for precise actuation with a repeatability of 20 microns to assure the process is accurate and delivers consistent quality.
- Properly designed heads are fairly heavy, so large DC stepper motors are used that provide the strength needed to actuate the head quickly.
- The laser MRC500 can be combined with a solder paste jet dispenser.

MRC500 soldering robotic cell
Learn more Read moreThe 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.
6 reasons to choose the mta MRC500 soldering platform
- You need a larger work area (500x500mm).
- You need the y-axis overhead (the y-axis is in the base of the TR300).
- Your process is semi-automated, but you need a free-standing station.
- The production is inline and requires conveyors.
- Your process is offline, but you need another form of material handling (rotary table, collaborative robot, etc.).
- The enclosure is large enough to support additional process such as automatic optical inspection.

TR300 soldering table-top robot
Learn more Read moreThe mta TR300 is a table-top soldering robot platform. This robot is purpose-built and standardized for semi-automated applications that require point-to-point soldering.
The table-top platform is a cost-effective solution to automate existing hand-soldering processes without the cost of fully-automated systems. Automating the solder process has several advantages over hand soldering. It produces highly consist joints, improved quality, higher throughput and it requires less skill and training than hand soldering.
This table-top soldering robot platform is also ideal for applications where human dexterity is required to position the parts. Indeed, operators can load and unload the parts in offline fixtures to minimize machine downtime.
The main features of our TR300 platform include: sturdy aluminum frame, 4-axis soldering robot, 300x300mm working area, 0.02mm repeatability, industrial PC controller with Windows 10 operating system, intuitive menu-driven mta MotionEditor software and air preparation & selectable 110/220VAC power connections.
Mechanical features
As the TR300 is a purpose-built solution, it can support any of mta’s soldering heads without compromise. The ball-screw axis and motors provide fast repeatable motion. Likewise, they are strong enough to support our heads that include our anti-jam wire feeder system and solder wire spool. There is no need to push solder wire through lengthy and problematic feed tubes. Therefore, the solder process is more accurate and reliable wire feed than feeding the wire long distances. Similarly, we pre-plumbed a large fume extraction hose with the nozzle located directly above the solder joint. Furthermore, light curtains and safety guarding are standard features. Lastly, the TR300 platform includes metal sides and door to protect operators with the laser soldering head.
5 reasons to choose the mta TR300 table-top robot
- The TR300 is the ideal platform for companies looking to automate current hand soldering processes.
- Your process is difficult to fully automate (e.g. you need human dexterity to load the parts.).
- Volume or product life do not justify fully automated production.
- The remaining processes are also off-line.
- The parts fit inside a 300x300mm work area.
