Introduction Application Specification Advantage Of Using Nanotechnology Manual And Maintenance Safety And Package

ArcaJet is an inkjet printer capable of printing different conductive and semi-conductive inks. By using this printer different types of electric circuits can be printed on various kinds of substrates that are wettable by colors.

Inkjet printing can be defined as the ability to form a steam of fluid droplets with a desired size along a certain path. Inks used for inkjet printing include a wide range of materials such as metals, ceramics, synthetic polymers, and also biomaterials, like alive cells.

ArcaJet incorporates a three-axis mechanism for the positioning of the head, moving it in a 40×40 cm range and maintaining a user-defined distance between the print head and the substrate. This device is equipped with 4 different heads for various types of inks, and it can print copper, silver, carbon and other conductive inks in multiple layers for various applications. Thickness of the printed layers can be adjusted by changing the color intensity of the print.

To make a circuit in each sub-layer, the sub-layer has to be fixed on the glass surface of the printing chamber, and then the image of the circuit (saved as a JPEG file with 1:1 scale) is printed on the substrate. Each material must be saved as a mask in a separate file. Care must be taken in the design process to overlap the layers properly. Thus, a circuit can easily be printed in no time.

This printer is compatible with oil-based, solvent-based or UV inks. The ink is placed in a special tank and fed to the ink supply system. Selection of the ink must be done carefully, and curing process of the ink needs to be performed based on the type of the ink and the necessary measures.

This device can be used for production of:

  • RFID tags
  • Biomedical sensors (blood glucose sensors, etc.)
  • Heaters (clothing heaters, heater films, car seat heaters, etc.)
  • Pressure-sensitive and touch circuits
  • Strain gauges
  • Shield circuits
  • Electromagnetic wave absorbing circuits
  • Flexible circuits
  • Light panels using electroluminescent paints

ArcaJet is an inkjet printer equipped with 4 heads for using four different types of ink. These inks can be UV, oil-based or solvent-based. Details of technical specifications are presented in the following Table.

 

The inks used in this device are based on nanoparticle inks. The particles used in the inks are under 20 nanometer in size, and larger particles can cause serious damage to the head and ink supply systems.

  • The device must be installed on a flat and sturdy surface. During installation, the device must be precisely leveled using the height-adjustment leveling glides. This process must be verified using a 2-axis precision level with 0.01 degree accuracy. Misalignment of the device can result in variations in the droplet size (in very small dimensions) and therefore prevent high-accuracy printing.
  • Proper cleaning and ventilation systems need to be installed in the environment.
  • The device must be placed as close to the UV and heater curing systems as possible.
  • Using an isolating transformer or UPS to power the device is recommended.
  • Printing images must be saved as JPEG, with each material designed and saved as a separate mask.
  • If multiple printing phases are needed (due to multiple layers), alignment markers must be added in the design.
  • The distance between the head and the substrate must not exceed 1 mm.
  • Head height must be adjusted based on laser distance sensor measurements.
  • Sublayers need to be fixed on the printer surface using magnet or adhesive tapes.
  • The curvature of the sublayer needs to be tightly controlled so as to prevent any wrinkles in the sublayer surface.
  • The curing process must be done in accordance with the technical specifications of the ink.
  • The UV source must be turned off when UV ink is not in use.
  • After the printing process, the ink must be fully discharged and the printing system needs to be cleaned using the appropriate solvents.
  • If the printer is not going to be used for more than three days, the head must be filled with oil.
  • For more details on how to use the device, refer to the device catalog and user guide.
  • A separate electrical panel must be used for the device.
  • The device must be placed close to the cleaning system.
  • The environment must be properly ventilated to prevent poisoning of the personnel from vapors of paint thinners and other solvents.
  • The device must be mounted on the fixed legs and raised until the wheels are not touching the ground.
