Case Studies

Industrial Inkjet


Inkjet printers are used in a wide variety of industrial applications: labelling, carpets, clothing, furniture manufacture, and many more.

Cambridge is a centre for inkjet development, and we have been involved with several different companies within the area.

A recent multi-board system for the inkjet industry required the following from us:

Design Process - from specification to production

Circuit Board
  • Hardware and firmware specification.
  • System management and functional partitioning.
  • Schematic layout of all system pcbs ( 6 in total ).
  • responsibility for liason with pcb layout engineer, component placement and layout verification.
  • generation of 'bill of materials' specifying all components and suppliers.
  • Testing of prototype boards and implementing design changes required for productionisation.
  • Firmware design & coding for prototype system.
  • Producing documentation required for production test engineers.
  • Assisting end-customers with installation of finished system, and interfacing to their factory production line.
Head Control PCB

Design Elements

  • Power supply and signal conditioning.
  • development of high-speed ( 250Mb/s ) communications protocols to allow multiple print heads to be controlled at the same time.
  • Hardware to implement the proprietary protocols, using Xilinx FPGAs and CPLDs, to allow them to be used to control several different print heads, from different manufacturers.
  • Implementation of USB 2.0 protocol for main system control, via Cypress USB processor.
  • System grounding and electrical isolation management.
  • VHDL firmware for Xilinx FPGAs and CPLDs.
