Whether in the development laboratory, in series production, in special applications or for the extension of existing production lines - the dispenseALL420 offers the solution for your dispensing challenge.
The dispenseALL420 automatic dispensing unit is in the tradition of the successful SMT placement systems from FRITSCH SMT. As a flexible system with many options and short set-up times, it is suitable for dispensing and jet tasks in electronics and mechanics. The manufactured quantities range from prototypes over small up to medium lots.
The universal carrier unit allows the use of up to three different dispensing valves simultaneously. Each dispensing head has its own motor drive with integrated encoder for position control. This allows any height on the workpiece carrier approach.
Its modular design, shortest set-up times for various products and easy programming with a graphical user interface make the dispenseALL420 a highly economical investment. The dispensing machine offers a great deal of flexibility thanks to numerous standard options. In addition, the dispenseALL420 forms a universal platform on which customer-specific requirements can be easily implemented.

The dispenseALL420 automatic dispensing unit is equipped as standard with a carrier unit for up to two dispensing heads. Optionally, it can be equipped with a carrier unit for three dispensing heads.
Each dispensing head has its own final drive. The DC motor with encoder allows free positioning of the head at any height. With the aid of the motor axis, the dispensing valves can be positioned both quickly and extremely precisely. The particularly slim design of the dispensing valves makes it possible to use all three positions of the carrier unit at the same time.
The dispensing machine software supports the use of all three dispensing heads simultaneously. The valves are arranged on the carrier unit in a row. This means that recurring dosages of up to three uses are possible in parallel. In series production, the dispensing capacity can be approximately tripled. Only the distances between the dispensing valves must be adjusted accordingly.
Structured, clear and optimized for the daily needs of production - this is how the user interface of the dispenseALL420 presents itself. Step by step, the user reaches his destination. Detailed help information is available for each function.
Dispensing programs can be created on the basis of CAD files or simply in the virtual editor. To make programming even easier, CAD drawings or scans of the workpiece carrier can be read in as background. The graphical interface makes programming as easy as in a drawing program.
To create a dispensing program the user drives with the integrated head camera to the actual position. Standard elements like dots, lines, curves and circles are available. Time-consuming pattern like for example meandering shapes on surfaces are possible by prepared forms. The virtual display of the camera image enables the exact alignment of the dispensing on workpiece or PCB. Therefore times of programming and runs for testing are shortened.
By means of a format editor, files from all CAD systems can be adapted with a few self-explanatory operating steps. The conversion process takes very little time and can be done offline on a separate PC.
Common Gerber files are used to create dispensing points using template thickness and SMD pad information. Dot size, size and shape are easy to set and optimize for each component and pad on the board.
By means of the X/Y-center coordinate and the drawing layer the allocation of the dosing position and quantity takes place.
The integrated library contains over 450 component models. This is one of the largest component library which is in this class available on market. All content items can be edited or new created.
If components, which are not part of the default library, need to be placed, a graphical editor is used to create a new component body in just a few steps.
With a series of software modules, the dispenseALL420 dispensing machine fully demonstrates its efficiency.
To correct the position of workpiece carriers, reference marks such as crosses, circles or diamonds can be read in automatically. In addition, it is possible to use the corners of a workpiece for alignment. Depending on the application and workpiece carrier, one to three reference marks can be used.
All system messages are transmitted to a separate PC in the network and displayed there. The user is informed automatically at the end of production.
The dispensing machine dispenseALL420 has been thoughtfully designed and optimized for cost-effective use. This is revealed by detailed solutions.
Inside, the dispenseALL offers a tidy, freely accessible working area. Workpiece carriers, laying devices and similar structures can be easily integrated. As a base, the interior offers a standard steel plate. Holder with magnetic feet can be adapted without tools to the current product. Further fixtures such as vacuum plates can be integrated in factory or retrofitted on site.
For fast conversion to other applications, the dispenseALL420 comes as standard with a set of magnet holders that can be freely positioned on the base plate. It offers sufficient height so that even double-sided printed circuit boards or 3D workpieces can be dispensed.
When applying varnishes or activators, some media produce fumes that can be explosive or harmful to health. Typical examples are media with solvents such as alcohol. For safe operation, the dispenseALL420 comes as standard with a connection for an extraction system.
The dispenseALL420 automatic dispensing machine adapts to a wide range of different tasks. The flexible design of the machine allows to integrate the supplements quickly and easily on site. Subsequent extensions also only lead to minimal downtime.
The exact positioning of the dispensing tip contributes to a high-precision dispensing result. But especially with one-way syringes or plastic nozzles the position of the dispensing changes significantly when the cartridge is changed.
The nozzle compensation measures all three directions (X, Y and Z) depending on the used dispensing tip and determines the required correction values. Thus, the nozzle moves after a cartridge change again exactly to the same position.
The laser height sensor is used for quick and precise measurement of the dispensing height on workpiece carriers or PCBs. The very compact design of the sensor allows integration directly on the dispensing head.
Solder pastes, glues and other dispensing media change their viscosity with temperature. In order to achieve consistent results, the temperature of the dispensing medium should be kept as constant as possible.
For this purpose, a media heating or media cooling is available, which can be integrated, for example, in the precision dispenser valve.
The suck-back module prevents the leaking or dripping of media from the syringe. Both low-viscosity media such as oil or water and extremely viscous media such as pastes that are applied at high pressure tend to form drops on the dispensing nozzle after dispensing. The suck-back module generates a retention vacuum in the dispensing pauses.
Dispensing media change their viscosity at elevated temperature. The up to 200°C controllable electric heating plates are used to heat assemblies, substrates, etc.
For flexible or thin circuit boards, a vacuum table can be integrated. The vacuum holder is simply inserted into the existing dispensing area. The integrated magnet holders allow a quick conversion without tools. In addition to standard sizes, customer-specific solutions are also available, for example for connecting workpiece carriers.
For integration in production lines, a transport system can be used. Numerous variants and options for different systems are available.
When entering, a pneumatic lifting plate brings the PCB or the workpiece carrier into position. The connection is made via a standardized SMEMA interface, READY contacts or customer-specific interfaces.
The module allows the user to control various options and features that are mounted in the machine room of the dispenseALL420. Whether for contactless nozzle compensation or customer-specific extensions, the automation interface provides the necessary control.
To prevent doors with standard widths of 80 cm from becoming an obstacle upon delivery, it is possible to install dispenseALL420 in a divisible manner. Both items are smaller than 80 cm.
