 Products

  • marco Hot Melt System
    The marco hot melt system is designed for dispensing of reactive polyurethane-based hot met adhesives. It is composed of a modular dispensing valve and a special tank for hot melt media with a capacity of 30 ccm....

  • The system is divided into three heating zones to ensure optimum medium processing. The medium melts progressively as it passes through the zones of increasing temperature. Once it has reached the dispensing area, the medium is at the perfect temperature. This careful processing is further improved by the optional use of a desiccant cartridge to reduce contact with humidity. The media tank is fitted with an ultrasound based level measurement system which can determine the filling level of the medium.

    These features ensure high process reliability. Like all systems from marco's mts range, the hot melt system is a modular system. This modular design has a crucial advantage: all parts which are in contact with the medium can be removed, cleaned or replaced individually. The modular dispensing valve can be operated with a continuous dispensing frequency of up to 500 Hz to allow for high path speed when dispensing hot melt media, achieving line widths or dot diameters of 0.4 mm depending on the adhesive.

    The marco melt system is suited for applications in the field of electronics manufacturing.

  • marco StepDot System for Solder Paste
    The marco StepDot valve enables high speed dispensing of solder paste and other viscous materials, such as silver-filled epoxies and non-conductive bonding adhesives....

  • The “macro” movement of the machine head with the “micro” movement of the StepDot
    valve creates an innovative hybrid drive. The z axis movement of the nozzle over the dispensing point
    is executed by the valve allowing continuous movement of the robot head during the dispensing process.This “on the fly” capability is 15 times faster than traditional needle dispensing and achieves speeds of 100 dots per second at a dot pitch of 0.2 to 0.4 mm.

    The small shifts in the x, y and z axes allow the valve to “step” in multiple directions (sideways, forwards, backwards) and to perform the critical dispensing movement at high frequencies. Both symmetrical and
    asymmetrical BGA patters can be achieved as well as discrete dot patterns for passive devices. “Dot on demand” parameters allow for dynamic adjustment of dot size for different sized components and optimisation of PCB dispensing patterns where warping and planarity are issues.

    The marco StepDot system provides smaller dot size, greater precision and improved repeatability. This breakthrough technology guarantees optimum solder paste dispensing for next generation miniaturised
    components and assembly packaging.

  • marco 2K Jet System
    The 2K Jet system contains one pump with one piston for each component A and B (ratio 1:1, 1:3, 1:10 and more, stepless), a mixing element and a modular dispensing valve. It is used to convey, mix and dispense (jet) two-component adhesives....

  • Both components must be liquid and without fillers. All parts which come into contact with the medium can be replaced quickly and easily, the use of disposable mixing elements ensures a smooth process flow.

    A large variety of valve inserts are available for the 2K Jet system depending upon the application. Diameter or shape can be selected depending on customer requirements.

    The mtv/dpa/* pump with integrated position measurement system generates a feed pressure of up to 72 bar and allows precise volume monitoring of both components.

    The system comes with a 10" touch-screen terminal with user-friendly software for monitoring and visualisation.

  • marco Filling of White LEDs System
    For the filling of white LEDs marco offers two systems. The system mts/led/w is composed of a dispensing valve and a media tank with a pneumatic pressure booster, the system mts/led/svwa contains a slider valve....

  • Adhesive with filler, usually two component adhesive (2K) is conveyed to the dispensing valve and applied to the LED. To make full use of the pot life of the 2K adhesive, it is filled into 30 ccm cartridges which can easily be replaced once they are past their pot life. The cartridge is mounted horizontally and rotatable in order to avoid the sedimentation of the filler material in the cartridge.

    The mechanically generated pressure in the media tank, which provides up to 18 bar feed pressure, ensures there is no contact with air so that no gas is absorbed by the medium. marco uses a special piston to optimise  pressure transfer to the fluid. A static mixer homogenises the medium once again as it passes through the fluid body, shortly before it is dispensed, ensuring sufficient mixing in the finished product to avoid light scattering and maintain constant and equal converter content. The mts/led/w system was specially developed by marco for use with highly abrasive media. The modular valve system mts/led/w does not close completely during the dispensing process. As a further advantage the slider valve system mts/led/svwa is lesss vulnerable for abrasion due to the principle of the slider valve.

    The advantages of both systems are twofold: the product life increases due to less friction on the sealing seat and the filler particles are not destroyed.

  • marco Bubble-free System with Volumetric Control
    The position sensors in the media supply tank of this marco system mounted either in the piston of the special cap or in the high pressure pump, provide an extremely precise reading of the dispensed volume....

  • The direct correlation between dispensing parameters (cycles, opening time, supply pressure) and dispensed volume means the dispensed volume can be kept at a constant level over a long period even if the media properties change over time. The deviation to the target volume does not exceed 1%. With media where viscosity increases over time for example, a readjustment of the opening time or of supply pressure will ensure that the volume set at the start of the process remains constant throughout the whole production shift (contents of one cartridge).
